Abstract
Description
Technical Field
[0001] This application relates to the field of display device technology, and in particular to a splicing device, a splicing interactive flat panel, and a smart blackboard. Background Technology
[0002] For ease of transport, the size of interactive displays is usually specified. In venues such as classrooms, offices, conference rooms, or outdoors, two or more interactive displays are typically combined to create a larger display area for better visual effects and more content. The splicing structure and technology of multiple interactive displays have a significant impact on the viewing experience and image continuity between the different displays. Summary of the Invention
[0003] The main technical problem solved by the embodiments of this application is to provide a splicing device, a splicing interactive flat panel and a smart blackboard, which can effectively adjust the splicing gap between two adjacent devices, thereby improving the visual experience and the continuity of the image.
[0004] One technical solution adopted in this application embodiment is to provide a splicing device, including an adjustment component and a mounting component. The adjustment component is used to install on one device and includes a first bracket, a driving component, and a locking component. The driving component and the locking component are movably disposed on the first bracket. The driving component has a first guide portion, and the locking component has a second guide portion and a first fixing portion. The first guide portion and the second guide portion are connected in cooperation. When the adjustment component is adjusted, the first guide portion of the driving component drives the second guide portion of the locking component to move, thereby driving the first fixing portion to move. The mounting component is used to install on another device and has a second fixing portion. The second fixing portion is detachably connected to the first fixing portion. When the driving component drives the locking component to move, the mounting component and the locking component move synchronously to adjust the splicing gap between the two external devices. Through the above structural configuration, on the one hand, the adjustment component becomes the main stress point, and the structural stability and sufficient strength of the adjustment component reduce the probability of splicing failure of the two devices due to deformation of the adjustment component; on the other hand, it allows the splicing gap between the two devices after splicing to be quickly adjusted at any time, improving the visual experience and continuity of the image.
[0005] In some embodiments, the locking component reciprocates along a first direction, and the driving component reciprocates along a second direction, with the first and second directions being perpendicular. The extension directions of the first guide portion and the second guide portion are inclined relative to the first direction. With this structural arrangement, the driving component and the locking component can be approximately wedge-shaped. When the driving component moves along the second direction, it can drive the locking component to move in the first direction, thereby pulling the mounting assembly relative to the adjusting assembly to adjust the splicing gap between the two external devices in the first direction.
[0006] In some embodiments, the first guide portion includes a first slide groove and a first slide rail, and the second guide portion includes a second slide groove and a second slide rail. The first slide groove is engaged with the second slide rail, and the first slide rail is engaged with the second slide groove. With the above structural arrangement, the slide groove and the slide rail are interlocked, enabling the driving component and the locking component to guide each other, and the driving component to lock the locking component.
[0007] In some embodiments, the driving component includes a screw and a driving block. The screw is connected to a first bracket, one end of the screw is connected to the driving block, and the other end of the screw extends outside the first bracket. When the driving screw rotates relative to the first bracket, the first screw drives the driving block to move in a second direction, thereby driving the locking component to move in a first direction. With the above structural configuration, the user can adjust the splicing gap between two external devices by rotating the screw. The adjustment process is simple and quick, reducing the user's adjustment time.
[0008] In some embodiments, the screw is screwed to the first bracket, and one end of the screw abuts against the drive block. When the screw is rotated, it moves relative to the first bracket in a second direction to drive the drive block. By configuring the screw and the first bracket as a threaded connection, the force is mainly concentrated on the first bracket during the process of the screw driving the drive block, and the first bracket supports the screw, which can reduce wear between the screw and the drive block.
[0009] In some embodiments, the screw is connected to the first bracket, and one end of the screw is screwed to the drive block. When the screw is rotated, the screw only rotates relative to the first bracket, and the drive block moves in the second direction. With the above structural arrangement, rotating the screw can cause the drive block to reciprocate in the second direction. Even when the adjusting component is unloaded, the drive block is not affected by its own gravity and will not move, that is, the screw has a self-locking effect on the drive block.
[0010] In some embodiments, the adjusting assembly further includes an elastic element disposed inside the first bracket. The elastic element is connected to both the first bracket and the drive block, and is used to drive the drive block to connect with the screw. The elastic element is located at the lower end of the drive block, and its elastic support force can overcome the weight of the drive block, preventing it from moving downwards naturally. Simultaneously, the elastic element provides an elastic force to the drive block, which helps improve the smoothness of sliding between the drive block and the locking component.
[0011] In some embodiments, the locking component includes a first sliding block and a second sliding block, which are symmetrically connected to both sides of the driving block along a second direction. The driving block simultaneously drives the first and second sliding blocks to move towards each other or away from each other. The mounting component has a first sidewall and a second sidewall disposed opposite to each other, each with a second fixing part. The first sliding block is connected to the first sidewall, or the second sliding block is connected to the second sidewall. By symmetrically distributing the first and second sliding blocks on both sides of the driving block, the adjustment component can be directly mounted on either the left or right side of an external device in the first direction. This allows the device to be connected to other display devices or non-display devices with mounting components on both sides, improving the versatility of the adjustment component and the mounting component, avoiding the need for additional design of adjustment and mounting components, and reducing production costs.
[0012] In some embodiments, the first fixing part includes a first locking section and a first limiting section. The first limiting section is disposed on the side of the first locking section opposite to the second guide section. The cross-section of the first locking section is smaller than the cross-section of the first limiting section, wherein both the cross-section of the first locking section and the cross-section of the first limiting section are perpendicular to the first direction. With the above structural configuration, when the driving block drives the first sliding block to move, under the limiting action of the first limiting section, the mounting component moves toward the adjusting component until the two external devices come into contact, completing the adjustment of the splicing gap between the two external devices.
[0013] In some embodiments, the second fixing part includes a first slot and a first opening. Along a third direction, the width of the first slot is equal to the width of the first latching segment, wherein the third direction is perpendicular to both the first and second directions. By setting the widths of the first slot and the first latching segment to be equal in the third direction, the mounting component and the locking component have only one fixed position in the third direction, allowing the two external devices to be almost flush in the third direction. This avoids the need to readjust the relative positions of the locking component and the mounting component in the third direction; adjustment is only required in the first direction, reducing adjustment steps and times, and improving adjustment efficiency.
[0014] This application also provides an embodiment of a splicing interactive flat panel, including a splicing device, a first display device, and a second display device. An adjustment component is disposed on the first display device, and a mounting component is disposed on the second display device. When the first display device and the second display device are spliced together, the second fixing part of the mounting component is mounted on the locking part of the adjustment component, and the splicing gap between the first display device and the second display device is adjusted by driving the driving component to move.
[0015] This application also provides an embodiment of a smart blackboard, including a splicing device, a main screen, and a secondary screen. The main screen is used for display and interaction, and the secondary screen is used for writing on the blackboard. An adjustment component is disposed on the main screen, and a mounting component is disposed on the secondary screen. When the main screen and the secondary screen are spliced together, the second fixing part of the mounting component is mounted on the locking part of the adjustment component, and the splicing gap between the main screen and the secondary screen is adjusted by driving the driving component to move.
[0016] In some embodiments, the main screen has a first top and a first bottom, with an adjustment component disposed at the first top and a third fixing part at the first bottom. The secondary screen has a second top and a second bottom, with a mounting component disposed at the second top and a fourth fixing part at the second bottom for engaging with the third fixing part. This structure enhances the connection strength between the main screen and the secondary screen, while the third and fourth fixing parts can also bear part of the weight of the secondary screen, preventing excessive stress at the connection between the first and second fixing parts.
[0017] The beneficial effects of this application's embodiments are as follows: The splicing device of this application includes an adjustment component and a mounting component. The adjustment component is used to install on one device and includes a first bracket, a driving component, and a locking component. The driving component and the locking component are movably disposed on the first bracket. The driving component has a first guide portion, and the locking component has a second guide portion and a first fixing portion. The first guide portion and the second guide portion are connected in cooperation. When the adjustment component is adjusted, the first guide portion of the driving component drives the second guide portion of the locking component to move and drives the first fixing portion to move. The mounting component is used to install on another device and has a second fixing portion. The second fixing portion is detachably connected to the first fixing portion. When the driving component drives the locking component to move, the mounting component and the locking component move synchronously to adjust the splicing gap between the two devices. Through the above structural design, on the one hand, the adjustment component becomes the main stress point, and the structural stability and sufficient strength of the adjustment component reduce the probability of splicing failure of the two devices due to deformation of the adjustment component; on the other hand, it allows the splicing gap between the two devices after splicing to be quickly adjusted at any time, improving the visual experience and continuity of the image.

[0026] To facilitate understanding of this application, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them.

[0027] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.
[0028] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.
[0029] For ease of transport, the size of interactive displays is usually specified. In venues such as classrooms, offices, conference rooms, or outdoors, to achieve better display effects and display more content, two or more interactive displays or non-display devices (such as blackboards, whiteboards, etc.) are typically combined to form a display device with a larger display area. The splicing structure and technology between multiple interactive displays, or between interactive displays and non-display devices, have a significant impact on the visual experience and continuity of the images across different displays.
[0030] Currently, related technologies use a locking buckle structure to splice two different devices. Specifically, a buckle is set on the edge of one device, and a locking buckle structure is set on the edge of the other device. The locking buckle and the buckle are fastened together to form a tight connection. However, the above structure has at least the following drawbacks: the locking buckle and the buckle have a single fastening position, making it impossible to adjust the splicing gap between the two devices after they are fastened together, which seriously affects the visual quality and continuity of the image; in addition, the buckle structure on one device is subjected to high stress and is prone to deformation, which may lead to splicing failure of the two devices.
[0031] Based on the above issues, please refer to Figure 1 This application provides a splicing device 100, which includes two separable parts: an adjustment component 10 and a mounting component 20. The adjustment component 10 is installed on one device 201, and the mounting component 20 is installed on another device 202. After the mounting slot on the mounting component 20 is fastened to the adjustment component 10, the splicing gap between the two devices is adjusted by adjusting the adjustment component 10. This structural design makes the adjustment component 10 the main stress point, and its stable structure and sufficient strength reduce the probability of splicing failure due to deformation of the adjustment component 10. Furthermore, the splicing gap between the two devices 201 and 202 after splicing can be quickly adjusted at any time, thereby improving the visual appeal and continuity of the image.
[0032] Please see Figures 2 to 4This application embodiment discloses a splicing device 100, which includes an adjustment component 10 and a mounting component 20, the latter being detachably mounted from the adjustment component 10. The adjustment component 10 is used to mount on one device, and the mounting component 20 is used to mount on another device. The adjustment component 10 includes a first bracket 11, a driving component 12, and a locking component 13. The driving component 12 and the locking component 13 are movably mounted on the first bracket 11. The driving component 12 has a first guide portion 1221, and the locking component 13 has a second guide portion 1311 and a first fixing portion 1312. The first guide portion 1221 and the second guide portion 1311 are both located inside the first bracket 11 and are connected in cooperation. The first fixing portion 1312 is located outside the first bracket 11 for connection with the mounting component 20. When the driving component 12 moves, under the connection of the first guide portion 1221 and the second guide portion 1311, the first guide portion 1221 of the driving component 12 drives the second guide portion 1311 of the locking component 13 to move, thereby driving the first fixing portion 1312 to move along the first direction X. The mounting assembly 20 is provided with a second fixing portion 211, which is used to detachably connect with the first fixing portion 1312. When the first fixing portion 1312 is connected to the second fixing portion 211, the mounting assembly 20 can move synchronously with the locking component 13, thereby adjusting the splicing gap between the two devices. With the above structural arrangement, after the adjustment assembly 10 and the mounting assembly 20 are connected, the splicing gap between the two devices can be quickly adjusted, thereby improving the visual experience and continuity of the image.
[0033] In some embodiments, please refer to Figure 4 The first bracket 11 limits and guides the driving component 12 and the locking component 13, allowing the locking component 13 to reciprocate along the first direction X. The driving component 12 reciprocates along the second direction Y, wherein the first direction X and the second direction Y are perpendicular, and the first direction X is the splicing direction of the two external devices. The extension direction of the first guide portion 1221 and the extension direction of the second guide portion 1311 are inclined relative to the first direction X. With the above structural arrangement, the driving component 12 and the locking component 13 can be approximately wedge-shaped. When the driving component 12 moves along the second direction Y, under the interaction of the first guide portion 1221 and the second guide portion 1311, the driving component 12 can drive the locking component 13 to move in the first direction X, thereby pulling the mounting assembly 20 relative to the adjusting assembly 10 to adjust the splicing gap of the two external devices in the first direction X.
[0034] In some embodiments, please refer to Figure 4 and Figure 5The first guide portion 1221 includes a first slide groove a1 and a first slide rail a2, and the second guide portion 1311 includes a second slide groove b1 and a second slide rail b2. The first slide groove a1 is connected to the second slide rail b2, and the first slide rail a2 is connected to the second slide groove b1. Through this structural arrangement, the slide groove and slide rail are interlocked, which on the one hand allows the driving component 12 and the locking component 13 to guide each other, making their movement smoother; on the other hand, it enhances the linkage between the driving component 12 and the locking component 13, so that the movement of the locking component 13 is restricted by the movement of the driving component 12, that is, the driving component 12 has a locking effect on the locking component 13. Specifically, when the driving component 12 is stationary relative to the first bracket 11, the first slide rail a2 and the second slide rail b2 are interlocked and abut against each other in the first direction X, thereby restricting the movement of the locking component 13 along the first direction X. Only when the driving component 12 moves along the second direction Y, under the action of the first guide portion 1221 and the second guide portion 1311, can the locking component 13 move along the first direction X.
[0035] In some embodiments, please refer to Figure 4 The driving component 12 includes a screw 121 and a driving block 122. The screw 121 is connected to the first bracket 11, with one end screwed or abutting against the driving block 122, and the other end extending outside the first bracket 11 for user operation. The other end of the screw 121 has an operating part. When the user drives the screw 121 to rotate relative to the first bracket 11 via the operating part, the screw 121 drives the driving block 122 to move along the second direction Y, thereby driving the locking component 13 to move along the first direction X. This structural design allows the user to adjust the splicing gap between two external devices by rotating the screw 121 after they are joined together. The adjustment process is simple and quick, greatly reducing the user's adjustment time.
[0036] In some embodiments, please refer to Figure 4The first bracket 11 has a screw hole (not shown in the figure), and the screw 121 passes through the screw hole, that is, the screw 121 is screwed to the first bracket 11, and one end of the screw 121 abuts against the drive block 122. When the screw 121 is rotated, the screw 121 moves relative to the first bracket 11 in the second direction Y, thereby pushing the drive block 122 to move. When the mounting assembly 20 is fastened to the first fixing part 1312 of the locking component 13, the locking component 13 is pulled to the right and moves to the right. Under the action of the first guide part 1221 and the second guide part 1311, the drive block 122 moves upward and abuts against the end of the screw 121. When the screw 121 is rotated, the screw 121 moves downward relative to the first bracket 11, which pushes the drive block 122 downward. Under the action of the first guide part 1221 and the second guide part 1311, the locking part 13 moves towards the screw 121, that is, the locking part 13 pulls the mounting assembly 20 to the left, thereby bringing the two devices closer together to reduce the splicing gap between them.
[0037] In this embodiment, by configuring the screw 121 and the first bracket 11 with a threaded connection, the force is mainly concentrated on the first bracket 11 during the movement of the drive block 122 driven by the screw 121. The first bracket 11 supports the screw 121, reducing wear between the screw 121 and the drive block 122 and extending the service life of the drive block 122. In other embodiments, please refer to [the relevant documentation / reference]. Figure 4 The screw 121 and the first bracket 11 can be indirectly connected via a metal part 123. For example, the metal part 123 can be fitted onto the first bracket 11, and the metal part 123 can be provided with a screw hole. The screw 121 is screwed onto the metal part 123. In this way, the first bracket 11 can be made of lower-cost and lighter plastic. The connection between the metal part 123 and the screw 121 can also ensure the connection strength between the two and reduce the wear of the screw 121 on the first bracket 11.
[0038] In some embodiments, please refer to Figure 4The adjusting assembly 10 also includes an elastic element 14, which is disposed inside the first bracket 11. The elastic element 14 is connected to both the first bracket 11 and the driving block 122, and is used to drive the driving block 122 to connect with the screw 121. As an example, the elastic element 14 is a spring that extends along the second direction Y. The two ends of the spring are connected to the first bracket 11 and the side of the driving block 122 away from the screw 121, respectively. Thus, the screw 121 and the spring are respectively disposed at the upper and lower ends of the driving block 122 along the second direction Y. Since one end of the screw 121 is abutted against the upper end of the drive block 122, when the adjusting component 10 is unloaded, i.e., when the mounting component 20 is not engaged with the adjusting component 10, the locking component 13 is not subjected to external tension. However, under the weight of the drive block 122 itself, the drive block 122 may move downwards, driving the locking component 13 to move closer to the screw 121. That is, when the adjusting component 10 is unloaded, the locking component 13 may retract into the first bracket 11. In this case, if it is necessary to splice the two devices, it will be difficult for the mounting component 20 to engage with the locking component 13 on the adjusting component 10. Therefore, an elastic element 14 is provided at the lower end of the drive block 122. The elastic support force of the elastic element 14 on the drive block 122 can overcome the weight of the drive block 122 and prevent the drive block 122 from moving downwards naturally. At the same time, the elastic element 14 provides an elastic force to the drive block 122, which helps to improve the smoothness of sliding between the drive block 122 and the locking component 13. Of course, in other embodiments, an elastic element 14 connected to the first bracket 11 can be provided at the upper end of the drive block 122, or an elastic element 14 connected to the first bracket 11 can be provided between the upper and lower ends of the drive block 122, as long as the force of the elastic element 14 can overcome the gravity of the drive block 122.
[0039] In other embodiments, please refer to Figure 4The first bracket 11 has a through hole (not shown in the figure). A portion of the screw 121 is not threaded, but a smooth portion passes through this through hole. The drive block 122 has a thread, and the threaded section of the screw 121 is screwed into the drive block 122. When the drive screw 121 rotates, it rotates relative to the first bracket 11 but does not move in the second direction Y. The drive block 122 moves in the second direction Y under the action of the thread. At this time, the drive block 122 and the screw 121 form a worm gear structure under the action of the first bracket 11. With the above structural configuration, rotating the screw 121 causes the drive block 122 to reciprocate in the second direction Y. Since the drive block 122 and the screw 121 form a worm gear structure, even when the locking component 13 of the adjusting assembly 10 is unloaded, the drive block 122 is not affected by its own gravity and does not move downwards. That is, in this embodiment, the screw 121 has a self-locking effect on the drive block 122. Of course, in other embodiments, based on the worm gear structure formed by the drive block 122 and the screw 121 under the action of the first bracket 11, an elastic element 14 can also be provided at the lower end of the drive block 122. The elastic element 14 provides an upward force to the drive block 122, so that the screw 121 drives the drive block 122 to move more smoothly.
[0040] In some embodiments, please refer to Figure 3 and Figure 4 The locking component 13 includes a first sliding block 131 and a second sliding block 132. Along the second direction Y, the first sliding block 131 and the second sliding block 132 are symmetrically connected to both sides of the driving block 122. The driving block 122 simultaneously drives the first sliding block 131 and the second sliding block 132 to move towards each other or away from each other. For example, when the screw 121 drives the driving block 122 downwards, the first sliding block 131 and the second sliding block 132 move towards each other; when the screw 121 drives the driving block 122 upwards, the first sliding block 131 and the second sliding block 132 move away from each other. The mounting assembly 20 has a first sidewall 21 and a second sidewall 22 arranged opposite to each other. Both the first sidewall 21 and the second sidewall 22 have a second fixing part 211. The first sliding block 131 is connected to the first sidewall 21, or the second sliding block 132 is connected to the second sidewall 22. With the first sliding block 131 and the second sliding block 132 symmetrically arranged on both sides of the driving block 122, the adjustment component 10 can be directly installed on the left or right side of the external display device in the first direction X. This allows a device to be spliced to be connected to another device with a mounting component 20 on both the left and right sides, improving the versatility of the adjustment component 10 and the mounting component 20, avoiding the need for additional design of the adjustment component 10 and the mounting component 20, and reducing production costs.
[0041] In some embodiments, please refer to Figure 4 and Figure 5 The first fixing part 1312 includes a first engaging section c1 and a first limiting section c2. The first limiting section c2 is disposed on the side of the first engaging section c1 opposite to the second guide part 1311. The cross-section of the first engaging section c1 is smaller than the cross-section of the first limiting section c2. Both the cross-sections of the first engaging section c1 and the first limiting section c2 are perpendicular to the first direction X. The first engaging section c1 is used to engage with the mounting component 20 to support the mounting component 20 in the second direction Y. The first limiting section c2 is used to abut against the mounting component 20 to prevent the mounting component 20 from separating from the locking member 13 in the first direction X, thereby realizing the connection between the adjusting component 10 and the mounting component 20. With the above structural configuration, when the second fixing part 211 of the mounting component 20 is fastened to the locking component 13, the driving block 122 drives the first sliding block 131 to move to the left. Under the limiting action of the first limiting segment c2, the mounting component 20 and the second housing move to the left synchronously until the second housing abuts against the first housing, thus completing the gap adjustment between the first housing and the second housing.
[0042] In some embodiments, please refer to Figure 3 The mounting component 20 has a first sidewall 21, and the first sidewall 21 has a second fixing part 211. The second fixing part 211 includes a first slot d1 and a first opening d2. Please refer to both. Figure 5 Along the third direction Z, the width of the first latching segment c1 is equal to the width of the first card slot d1, and the first latching segment c1 is used to latch and connect with the first card slot d1. The first direction X, the second direction Y, and the third direction Z are all perpendicular to each other, and the third direction Z can also be understood as the direction perpendicular to the screen. The first opening d2 communicates with the first card slot d1, and the first latching segment c1 of the locking component 13 enters the first card slot d1 through the first opening d2. The first limiting segment c2 abuts against the first side wall 21, and the first side wall 21 is located between the first limiting segment c2 and the second guide portion 1311. By setting the widths of the first slot d1 and the first latching segment c1 to be equal in the third direction Z, when the mounting component 20 is fastened to the locking component 13, the mounting component 20 and the locking component 13 have only one fixed position in the third direction Z. This allows the external device 201 and the external device 202 to be almost flush in the third direction Z. This avoids the need to readjust the relative positions of the locking component 13 and the mounting component 20 in the third direction Z. Adjustment is only required in the first direction X, reducing adjustment steps and times and improving adjustment efficiency.
[0043] In some embodiments, please refer to Figure 3 and Figure 4The first opening d2 is located at the bottom of the first slot d1 and communicates with it. Along the second direction Y, the position on the first slot d1 opposite to the first opening d2 is closed. When two devices are spliced together, the mounting component 20 is fastened to the locking component 13 from top to bottom, that is, the first locking segment c1 enters the first slot d1 from the first opening d2 along the second direction Y. With this structure, the upper end of the first slot d1 can abut against the first locking segment c1, and the locking component 13 can bear the weight of the other device. Thus, when the user mounts the mounting component 20 of the other device to the adjustment component 10 of one device, they can release their hand. At this time, the two devices can be relatively fixed. The gap between the two external devices can be adjusted simply by rotating the screw 121. The operation is simple, and when adjusting the splicing gap in the first direction X, the user no longer needs to lift and hold the other device.
[0044] In some embodiments, please refer to Figure 1 and Figure 2 This application also provides an embodiment of a smart blackboard 200, which is typically used in classrooms, conference rooms, and other scenarios requiring teaching demonstrations and explanations. The smart blackboard 200 includes the splicing device 100 described in any of the above embodiments, as well as a main screen 201 and a secondary screen 202. The main screen 201 is used to display content and interact with the user, while the secondary screen 202 is used for writing on the blackboard. The adjustment component 10 in the splicing device 100 is disposed on the main screen 201, and the mounting component 20 is disposed on the secondary screen 202, which is located on the side of the main screen 201. When the main screen 201 and the secondary screen 202 are spliced together, the second fixing part 211 of the mounting component 20 is mounted on the locking component 13 of the adjustment component 10, and the splicing gap between the main screen 201 and the secondary screen 202 is adjusted by driving the driving component 12 to move.
[0045] In some embodiments, please refer to Figure 1 and Figure 2Along the second direction Y, the main screen 201 has a first top 201a and a first bottom 201b, with the adjustment component 10 disposed on the first top 201a and the first bottom 201b having a third fixing part 2011. Along the second direction Y, the sub-screen 202 has a second top 202a and a second bottom 202b, with the mounting component 20 disposed on the second top 202a and the second bottom 202b having a fourth fixing part 2021, which is used to engage with the third fixing part 2011. With the above structural configuration, when the secondary screen 202 is spliced to the side of the main screen 201, the top of the main screen 201 is connected to the top of the secondary screen 202 through the adjustment component 10 and the mounting component 20, and the bottom of the main screen 201 is connected to the bottom of the secondary screen 202 through the third fixing part 2011 and the fourth fixing part 2021. The main screen 201 and the secondary screen 202 form a snap-fit connection at the top and bottom, further enhancing the connection strength between the two. At the same time, the third fixing part 2011 and the fourth fixing part 2021 can also bear part of the weight of the secondary screen 202, avoiding excessive stress at the connection between the first fixing part 1312 and the second fixing part 211.
[0046] In some embodiments, there may be two secondary screens 202. Typically, the main screen 201 is located in the center of the viewing area, for example, the main screen 201 is installed in the middle of the podium, and the two secondary screens 202 are respectively located on both sides of the main screen 201. This can further increase the overall display area of the main screen 201 and the secondary screens 202, and the secondary screens 202 on the left and right sides provide more writing space for the user (teacher).
[0047] In some embodiments, please refer to Figure 6 The third fixing part 2011 includes a second latching section 20111 and a second limiting section 20112. The second limiting section 20112 is disposed on the side of the second latching section 20111 opposite to the main screen 201. The cross-section of the second latching section 20111 is smaller than the cross-section of the second limiting section 20112. Both the cross-sections of the second latching section 20111 and the cross-section of the second limiting section 20112 are perpendicular to the first direction X. The fourth fixing part 2021 includes a second slot 20211 and a second opening 20212 along the third direction Z. The width of the second latching section 20111 is equal to the width of the second slot 20211. The second latching section 20111 is used to latch with the second slot 20211. The second opening 20212 is located at the bottom of the second card slot 20211 and communicates with the second card slot 20211. The second card segment 20111 enters the second card slot 20211 through the second opening 20212 to support the second housing in the second direction Y. The second limiting segment 20112 abuts against the sub-screen 202. The second limiting segment 20112 is used to prevent the fourth fixing part 2021 from separating from the third fixing part 2011 in the first direction X, so as to realize the bottom fixed connection of the main screen 201 and the sub-screen 202.
[0048] In some embodiments, please refer to Figure 7 This application also provides an embodiment of a splicing interactive flat panel, which includes the splicing device 100 in any of the above embodiments, as well as a first display device 301 and a second display device 302. Both the first display device 301 and the second display device 302 are used to display content and interact with the user. The adjustment component 10 in the splicing device 100 is disposed on the first display device 301, and the mounting component 20 is disposed on the second display device 302. When the first display device 301 and the second display device 302 are spliced together, the second fixing part 211 of the mounting component 20 is mounted on the locking component 13 of the adjustment component 10. By driving the driving component 12 to move, the second display device 302 moves closer to the first display device 301, thereby adjusting the splicing gap between the first display device 301 and the second display device 302.
[0049] The splicing device 100 of this application embodiment includes an adjustment component 10 and a mounting component 20, which are detachably disposed from the adjustment component 10. The adjustment component 10 is used to be mounted on one device, and the mounting component 20 is used to be mounted on another device. The adjustment component 10 includes a first bracket 11, a driving component 12, and a locking component 13. The driving component 12 and the locking component 13 are movably disposed on the first bracket 11. The driving component 12 is provided with a first guide portion 1221, and the locking component 13 is provided with a second guide portion 1311 and a first fixing portion 1312. The first guide portion 1221 and the second guide portion 1311 are both located inside the first bracket 11 and are connected in cooperation. The first fixing portion 1312 is located outside the first bracket 11 for connection with the mounting component 20. When the driving component 12 moves, under the connection of the first guide portion 1221 and the second guide portion 1311, the first guide portion 1221 of the driving component 12 drives the second guide portion 1311 of the locking component 13 to move, thereby driving the first fixing portion 1312 to move along the first direction X. The mounting component 20 is provided with a second fixing portion 211, which is used to detachably connect with the first fixing portion 1312. When the first fixing portion 1312 is connected to the second fixing portion 211, the mounting component 20 can move synchronously with the locking component 13, thereby adjusting the splicing gap between the two external display devices. Through the above structural arrangement, on the one hand, the adjusting component 10 becomes the main stress point, and the structure of the adjusting component 10 is stable and has sufficient strength, reducing the probability of deformation of the adjusting component 10 causing the splicing of the two devices to fail; on the other hand, the splicing gap between the two devices after splicing can be quickly adjusted at any time, improving the screen viewing experience and screen continuity of the two external devices.
