Description

[0001] The utility model relates to the technical field of electronic screen equipment, in particular to a magnetic attraction mechanism, a floor tile screen and a ground screen. Background Art

[0002] The floor screen is usually composed of multiple floor tile screens arranged in sequence. In order to ensure the flatness of the floor screen, a mounting frame is usually provided under the floor tile screen. The mounting frame can not only support the floor tile screen, but also ensure the accurate positioning of the floor tile screen when it is connected in sequence.

[0003] However, when installing a floor screen on a flat surface to be installed, such as an indoor tile surface or a flat cement floor, it is necessary to first install a mounting bracket on the surface to be installed, and then install the floor tile screen on the mounting bracket in sequence. Since the flat surface to be installed does not have the problem of installation leveling and the installation is unstable, the mounting bracket can only play a positioning role at this time. Therefore, the method of using the mounting bracket for positioning is not only difficult to install, but also time-consuming, labor-intensive and costly. Utility Model Content

[0059] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.

[0060] In the description of this utility model, unless otherwise specified or limited, the terms "connected," "connect," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0061] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0062] In the description of this embodiment, the terms "upper," "lower," "right," and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0063] Typically, floor screens are installed in well-decorated buildings such as stages or immersive venues to provide audiences or visitors with a good immersive experience. Therefore, floor screens are usually installed on a relatively flat surface to be installed. Typically, a mounting frame that supports and positions the screen is first installed on the surface to be installed, and then the screen is mounted on the mounting frame. However, this method, with the addition of a mounting frame, makes installation of floor screens more complicated and costly. It also increases the height of the floor screen, further reducing the space available for the installation and increasing the sense of oppression for the audience or visitors.

[0064] Therefore, please refer to Figure 1 As shown, the embodiment of the present application provides a floor screen that can be quickly installed without the need for additional positioning and supporting devices, saving time and effort, and having low costs. Moreover, since the mounting frame is reduced, only the floor tile screen 1 is laid on the surface to be installed, which reduces the height of the floor screen and does not take up too much space, thereby ensuring a good experience for the audience or visitors.

[0065] The ground screen can be laid on a flat concrete ground in an open-air square, or on a flat floor indoors. As long as the surface to be installed is flat, the ground screen of the embodiment of the present application can be laid. This embodiment does not make any specific restrictions on the surface to be installed.

[0066] Specifically, in some embodiments of this application, please refer to Figure 1 As shown, the floor screen includes a plurality of sequentially arranged floor tiles 1. The side walls of two adjacent floor tiles 1 are attracted together by magnetic force. After the previous floor tile 1 has been installed, the next floor tile 1 only needs to be placed in the approximate installation position. Under the action of the magnetic force, the side wall of the next floor tile 1 will be attracted and connected with the side wall of the previous floor tile 1, thus completing the installation of the next floor tile 1, which is easy to operate. When the floor screen needs to be removed, the two adjacent floor tiles 1 can be separated by applying a force greater than the attraction between the two adjacent floor tiles 1, which is simple and easy.

[0067] It is understood that, in general, the floor screen is installed on the entire floor surface of the room, and the indoor walls can serve as the boundaries of the floor screen, limiting the position of the floor tile screen 1. For floor screens installed in open outdoor areas or in a part of the room, L-shaped limit plates can be installed at the four corners of the surface to be installed to limit the floor tile screen 1 at the four corners of the floor screen, thereby achieving position control for the entire floor screen, with a simple structure and low cost.

[0068] For further information, please refer to Figures 2 and 3 As shown, in some embodiments of the present application, a possible structure of the floor tile screen 1 is that the floor tile screen 1 includes a frame 11 and a screen body 13 installed on the frame 11, a magnetic attraction mechanism 12 is provided on the circumferential side wall of the frame 11, and the magnetic attraction mechanism 12 includes a first magnetic group 121 and a second magnetic group 122 that attract each other, a first magnetic group 121 is provided on the side wall surface on one diagonal side of the frame 11, and a second magnetic group 122 is provided on the side wall surface on the other diagonal side of the frame 11. Figure 1 In the example of two floor tiles A and B, which are adjacent to each other on the left and right sides of the middle of the floor screen, after floor tile A is installed, the two first magnetic groups 121 on the diagonal side of floor tile A are attracted and aligned with the second magnetic group 122 on the right side wall of floor tile C and the second magnetic group 122 on the lower side wall of floor tile D, respectively. The second magnetic group 122 on the other side of the diagonal side of floor tile A is exposed. When floor tile B is installed, the first magnetic group 121 on the left and front sides of floor tile B are attracted to the second magnetic group 122 on the right side of floor tile A and the second magnetic group 122 on the rear side wall of floor tile E, respectively. Then, the second magnetic members 1212 on the right and rear side walls of floor tile B are exposed, and so on, thus completing the installation of the floor screen.

[0069] To ensure the strength of attraction, in some embodiments of the present application, the number of the first magnetic group 121 on the side wall of the frame 11 where the first magnetic group 121 is provided is at least one. When the number of the first magnetic group 121 is one, the first magnetic group 121 is located in the center of the side wall. When the number of the first magnetic group 121 is two, there is a first magnetic group 121 on each side of the side wall of the frame 11. When the number of the second magnetic group 122 is more than two, at least three first magnetic groups 121 are evenly distributed on the side wall of the frame 11. The number of the second magnetic group 122 on the side wall where the second magnetic group 122 is provided is also at least one. The arrangement position of the second magnetic group 122 is the same as that of the first magnetic group 121, and will not be repeated here.

[0070] If you want to present a preset graphic or pattern on a floor screen composed of multiple floor tiles 1 arranged in sequence, you need to couple the multiple floor tiles 1 that make up the floor screen together. Please refer to Figures 3 and 4 As shown, in some embodiments of the present application, the screen body 13 is coupled to the frame body 11, and support feet 114 are provided at the four corners of the side of the frame body 11 facing away from the screen body 13. The support feet 114 abut against the surface to be installed, so that there is an installation gap between the side of the frame body 11 facing away from the screen body 13 and the surface to be installed. An interactive line connector 111, a signal line connector 112 and a power line connector 113 are provided on the side of the frame body 11 facing away from the screen body 13. Two adjacent floor tile screens 1 are connected together by signal lines to respectively connect the interactive connector, the signal line connector 112 and the power line connector 113, thereby realizing the coupling of all floor tile screens 1, and the installation gap can ensure the installation space for all connecting wires.

[0071] Normally, various signal lines are connected together before two adjacent floor tile screens 1 are installed together. Since the signal lines are soft and their shapes can change to a certain extent, connecting the signal lines together first and then installing the two adjacent floor tile screens 1 together will not affect the installation of the floor tile screens 1.

[0072] Although the attraction of the first magnetic group 121 and the second magnetic group 122 can realize the magnetic attraction connection between two adjacent floor tile screens 1, it cannot guarantee the accurate installation of the downstream floor tile screen 1 when the first magnetic group 121 and the second magnetic group 122 are attracted. Therefore, in some embodiments of the present application, please refer to Figures 2 to 8 As shown, a limit sounder 1213 is provided on the first magnetic group 121, and a matching structure 1222 is provided on the second magnetic group 122. When the limit sounder 1213 matches the matching structure 1222, the first magnetic group 121 and the second magnetic group 122 are aligned and attracted, thereby limiting the position of the attraction connection between the downstream floor tile screen 1 and the upstream floor tile screen 1, ensuring the precise connection between the downstream floor tile screen 1 and the upstream floor tile screen 1. When the limit sounder 1213 matches the matching structure 1222, the limit sounder 1213 will also emit a prompt sound to remind the operator that the floor tile screen 1 has been installed in place, thereby facilitating the operator to identify the installation status of the floor tile screen 1 and ensuring that the floor tile screen 1 is accurately installed in place.

[0073] Specifically, in some embodiments of this application, please refer to Figures 5 to 8As shown, the first magnetic group 121 includes a first cover plate 1211 and at least one magnetic member 1212. The first cover plate 1211 has a first side surface 1201 and a second side surface 1202 opposite to each other. The first side surface 1201 is in contact with the frame 11. The magnetic member 1212 is located between the first side surface 1201 and the frame 11. The position limiting sound generator 1213 is disposed on the second side surface 1202. The second magnetic group 122 includes a second cover plate 1221 and at least one magnetic member 1212. The second cover plate 1221 has an inner side surface 1207 and an outer side surface 1204 opposite to each other. The inner side surface 1207 is in contact with the frame 11. The magnetic member 1212 is disposed between the inner side surface 1207 and the frame 11. A matching structure 1222 is disposed on the outer side surface 1204 to match the position of the position limiting sound generator 1213, thereby ensuring the positional installation accuracy of the floor tile screen 1 after the position limiting sound generator 1213 and the matching structure 1222 match. The first cover plate 1211 and the second cover plate 1221 can protect the magnetic member 1212 from damage caused by external influences. The magnetic member 1212 can be one, two, three, four, or even more, as long as the magnetic attraction requirements are met. This application does not impose specific restrictions. The first cover plate 1211 and the second cover plate 1221 are made of a magnetic member, such as alloy steel or other materials that can be attracted by magnetic force, and are used to install the magnetic member 1212 on the side wall of the floor tile screen 1.

[0074] It is understandable that the thinner the material thickness of the first cover plate 1211 and the second cover plate 1221 is, the greater the magnetic force of the magnetic member 1212 is. Therefore, in some embodiments of the present application, please refer to Figure 6 、 Figure 8 As shown, at least one limiting groove 1206 is provided on each of the first side surface 1201 and the inner side surface 1207, and the magnetic member is installed in the limiting groove 1206, and the limiting groove 1206 and the magnetic member are arranged in a one-to-one correspondence. The limiting groove 1206 can not only limit the position of the magnetic member 1212, so that the magnetic member will not be separated when the first cover plate 1211 and the second cover plate 1221 are installed on the side wall of the frame 11, but also can reduce the thickness of the first cover plate 1211 and the second cover plate 1221 covering the magnetic member 1212, thereby increasing the magnetic attraction force of the first magnetic group 121 and the second magnetic group 122, and ensuring the connection strength between the two adjacent floor tile screens 1. Optionally, the thickness of the magnetic piece 1212 is the same as the depth of the limiting groove 1206, so that when the first cover plate 1211 and the second cover plate 1221 are connected to the frame 11, the magnetic piece 1212 will not be damaged by excessive pressure, and the magnetic piece 1212 will not be able to move relative to the limiting groove 1206 after the first cover plate 1211 and the second cover plate 1221 are connected to the frame 11.

[0075] Of course, in other embodiments of the present application, the first magnetic group 121 includes a first magnetic plate, which is arranged on the side wall surface of the clamp, and the position limiting sounder 1213 is arranged in the center of the side of the first magnetic plate facing away from the frame 11. The second magnetic group 122 includes a second magnetic plate, which is arranged on the side wall surface of the frame 11, and the matching structure 1222 is arranged on the side of the second magnetic plate facing away from the frame 11 to match the position of the position limiting sounder 1213. The first magnetic plate and the second magnetic plate can be one of a magnet, an electromagnet, and an electromagnetic coil, as long as they have magnetic force, and this application does not make specific restrictions. The direct attraction between the first magnetic plate and the second magnetic plate makes the magnetic force of attraction greater, thereby ensuring the reliability of the connection between the first attraction group and the second magnetic group 122.

[0076] In some embodiments of this application, please refer to Figure 5 and Figure 7 As shown, the limit sounder 1213 can be a wave bead, and the matching structure 1222 is a wave bead groove. When the first magnetic group 121 and the second magnetic group 122 abut, the round beads on the wave bead move inward to compress the spring. When the wave bead is aligned with the wave bead groove, the round beads are reset under the action of the spring elastic force. When the round beads are reset, they collide with the outer wall of the wave bead to make a sound, which is the prompt sound. Of course, the limit sounder 1213 can also be a first sensor, and the matching structure 1222 can be a second sensor. When the first sensor and the second sensor are aligned, one of the first sensor and the second sensor or both of them emit a prompt sound. As long as the attraction between the first magnetic group 121 and the second magnetic group 122 can be limited and the prompt sound can be emitted after alignment and attraction, this application does not make any specific restrictions.

[0077] It is understandable that when the operator installs the floor tile screen 1, the installation direction of the floor tile screen 1 is not fixed. The operator can first place the floor tile screen 1 in the approximate position from top to bottom and then align it magnetically, or move the floor tile screen 1 from left to back or from back to front to the approximate position and then align it magnetically. When the limit sounder 1213 is a wave bead and the matching structure 1222 is a wave bead groove, if the outer side surface 1204 of the second cover plate 1221 is directly pressed on the wave bead, the wave bead can be directly compressed. However, if the outer side surface 1204 of the second cover plate 1221 is aligned with the second side surface 1202 of the first cover plate 1211 by sliding, for example, sliding from top to bottom, or sliding from back to front, then the circumferential ridges of the outer side surface 1204 of the second cover plate 1221 will first abut against the wave bead. At this time, the circumferential ridges of the outer side surface 1204 of the second cover plate 1221 will apply a shear force to the wave bead at the abutment position with the wave bead, and the pressure of the shear force decomposed into the wave bead is relatively small, so the wave bead will hinder the sliding of the second cover plate 1221 relative to the first cover plate 1211. Therefore, please refer to Figure 7As shown, in some embodiments of the present application, a guide slope 1205 is provided on the circumference of the outer side surface 1204 of the second cover plate 1221 at the matching structure 1222. When the second cover slides relative to the first cover plate 1211, the ridge line of the outer side surface 1204 moves relative to the wave ball. When it moves to the guide slope 1205, the compression force applied to the wave ball by the guide slope 1205 increases, so that the round ball of the wave ball moves inward to compress the spring. As the second cover plate 1221 continues to slide relative to the first cover plate 1211, the wave ball is aligned with the wave ball groove, thereby realizing the alignment and attraction of the first magnetic group 121 and the second magnetic group 122, thereby ensuring the precise installation of the floor tile screen 1.

[0078] Corresponding to the first magnetic plate and the second magnetic plate, a guide slope 1205 is provided at the matching structure 1222 on the circumferential direction of the side of the second magnetic plate facing away from the frame 11. The function of the guide slope 1205 is the same as that of the guide slope 1205 on the second cover plate 1221, and will not be repeated here.

[0079] Furthermore, in some embodiments of the present application, the limit sounder 1213 is located at the center of the second side surface 1202 or the side surface of the second magnetic plate facing away from the frame 11, thereby ensuring that the first magnetic group 121 and the second magnetic group 122 can be precisely aligned without deflection.

[0080] If both the first magnetic member 1212 and the second magnetic member 1212 protrude from the side wall of the frame 11, then after two adjacent floor tile screens 1 are connected, a gap equal to the thickness of the first magnetic member 1212 and the thickness of the second magnetic member 1212 will appear between the adjacent screen bodies 13, thereby affecting the aesthetics and display effect of the floor screen body 13. Therefore, in some embodiments of the present application, please refer to Figure 3 and Figure 4 As shown, a mounting groove 115 is provided on the side wall of the frame 11, and the first magnetic group 121 and the second magnetic group 122 are both located in the mounting groove 115. The first magnetic group 121 and the second magnetic group 122 are both flush with the side wall of the frame 11 on the side facing away from the frame 11. Of course, the round beads on the wave beads are protruding from the side wall of the frame 11 when the floor tile screen 1 is not installed, and the first cover plate 1211 on the first magnetic group 121 or the side of the first magnetic plate facing away from the frame 11 is flush with the side wall of the frame 11. Therefore, when the first magnetic group 121 and the second magnetic group 122 are aligned and attracted, the side walls of the two adjacent frames 11 fit together, and there will be no gap between the screen bodies 13 of the two adjacent floor tile screens 1, thereby ensuring the aesthetics and display effect of the ground screen body 13.

[0081] In order to facilitate the installation of the first magnetic group 121 and the second magnetic group 122 in the installation slot 115, in some embodiments of the present application, please refer to Figure 4As shown, a first limiting structure 116 is provided on the wall of the mounting groove 115, and a second limiting structure 1203 is provided on the side of the first magnetic group 121 and the second magnetic group 122 facing the frame 11. The first limiting structure 116 and the second limiting structure 1203 match to limit the position of the first magnetic group 121 in the mounting groove 115 and the position of the second magnetic group 122 in the mounting groove 115. This facilitates the installation of the connecting member 1215 connecting the first cover plate 1211 and the second cover plate 1221 to the frame 11 in the mounting hole in the mounting groove 115. The connecting member 1215 can be a screw or an adhesive. If the connecting member 1215 is adhesive, the first limiting structure 116 and the second limiting structure 1203 can ensure that the first cover plate 1211, the second cover plate 1221 or the first magnetic plate, the second magnetic plate are accurately bonded in the installation groove 115, thereby ensuring the accuracy of the installation position of the floor tile screen 1 when the first magnetic group 121 and the second magnetic group 122 are attracted.

[0082] In some embodiments of this application, please refer to Figure 4 、 Figure 6 and Figure 8 As shown, one of the first limiting structure 116 and the second limiting structure 1203 can be a cylinder, and the other can be a cylindrical groove that matches the cylinder. The cylinder can extend into the cylindrical groove to achieve the positioning function. Of course, the first limiting structure 116 and the second limiting structure 1203 can also be two interlocking columns that can be snapped together. As long as the limiting function of the first limiting structure 116 and the second limiting structure 1203 can be achieved after the matching, this embodiment does not make specific restrictions.

[0083] In some embodiments of the present application, the frame 11 is made of plastic material, so that only the first magnetic group and the second magnetic group on the entire frame 11 have magnetic force and magnetic attraction, preventing the first magnetic group from attracting other parts of the frame 11 than the second magnetic group, thereby ensuring the installation accuracy of the floor tile screen 1. Furthermore, in some embodiments of the present application, the frame 11 is integrally formed, thereby increasing the structural strength of the frame 11 and being able to bear greater weight.

[0084] Due to technical limitations, the maximum size of the small display modules 131 that currently make up the screen 13 is a square with a side length of about 300 mm. If the frame 11 is exactly matched with the small display modules 131, the number of frames 11 required will be large and the cost will be high. Therefore, in some embodiments of the present application, the screen 13 is composed of four small display modules 131, and the four small display modules 131 are installed on the frame 11 in sequence, thereby reducing the number of frames 11 and reducing costs. Of course, if the size of the display module 131 can be made larger in the future, the frame 11 can also be used alone to support a single display module 131. This application does not make specific restrictions on the size of the frame 11 and the number of small display modules 131 supported.

[0085] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
