Description

Technical Field

[0001] The present application relates to the field of display devices, and particularly to an intelligent blackboard, a display device, and a splicing device. Background Art

[0002] Due to the large volume of the intelligent blackboard, the main screen and the secondary screen of the intelligent blackboard are usually disassembled and carried separately, and then the main screen and the secondary screen are spliced into one body by a splicing device such as a buckle or a screw during installation.

[0003] However, the existing splicing devices such as buckles or screws are generally arranged at the top and bottom of the rear shell of the intelligent blackboard, which results in difficulties for users to operate the buckles or screws when installing and disassembling, as they need to climb to the top of the intelligent blackboard and lie on the bottom of the device. Summary of the Invention

[0004] The purpose of the present application is to provide an intelligent blackboard, a display device, and a splicing device, which can facilitate the quick disassembly and assembly of the main screen and the secondary screen.

[0005] To achieve the above purpose, on the one hand, the present application provides an intelligent blackboard, which includes a main screen, a secondary screen, a locking component, and a plugging component; the locking component includes a first base and an elastic clamping member, the first base is connected to the main screen, a limiting hole is formed on one side of the first base close to the plugging component, the elastic clamping member is connected to the first base, and a part of the elastic clamping member protrudes from the hole wall of the limiting hole; the plugging component is connected to the secondary screen, the plugging component includes a plugging part, a clamping groove is formed on the side surface of the plugging part, and the plugging part is located on the center line of the limiting hole; when the main screen and the secondary screen are spliced, the plugging part is inserted into the limiting hole, and the plugging part cooperates with the limiting hole, and the plugging part forces the elastic clamping member to retract in a direction away from the limiting hole, so that the elastic clamping member is clamped in the clamping groove; when the main screen and the secondary screen are separated, the plugging part forces the elastic clamping member to retract in a direction away from the limiting hole, so that the elastic clamping member is disengaged from the clamping groove.

[0006] To achieve the above object, on the other hand, the present application further provides a display device, which at least includes an adjacent first display unit and a second display unit; a limiting hole is formed on one side of the first display unit close to the second display unit, an elastic clamping member is connected to the first display unit, and a part of the elastic clamping member protrudes from the hole wall of the limiting hole; a plug-in portion is provided on one side of the second display unit close to the first display unit, the plug-in portion extends from the second display unit towards the first display unit, a clamping groove is formed on the side surface of the plug-in portion, and the plug-in portion is located on the center line of the limiting hole; when the first display unit and the second display unit are spliced, the plug-in portion is inserted into the limiting hole, and the plug-in portion cooperates with the limiting hole, and the plug-in portion forces the elastic clamping member to retract in a direction away from the limiting hole, so that the elastic clamping member is clamped in the clamping groove; when the first display unit and the second display unit are separated, the plug-in portion forces the elastic clamping member to retract in a direction away from the limiting hole, so that the elastic clamping member is disengaged from the clamping groove.

[0007] To achieve the above object, on the other hand, the present application further provides a splicing device, which at least includes a locking component and a plugging component; the locking component includes a first base and an elastic clamping member, a limiting hole is formed on one side of the first base, the elastic clamping member is connected to the first base, and a part of the elastic clamping member protrudes from the hole wall of the limiting hole; the plugging component includes a plug-in portion, a clamping groove is formed on the side surface of the plug-in portion, when the plug-in portion is inserted into the limiting hole, the plug-in portion cooperates with the limiting hole, and the plug-in portion forces the elastic clamping member to retract in a direction away from the limiting hole, so that the elastic clamping member is clamped in the clamping groove; when the plug-in portion is disengaged from the limiting hole, the plug-in portion forces the elastic clamping member to retract in a direction away from the limiting hole, so that the elastic clamping member is disengaged from the clamping groove.

[0008] It can be seen that in the technical solution provided by this application, a locking component is installed on the main screen, and a plugging component is installed on the secondary screen. A limiting hole is provided on one side of the first base of the locking component close to the plugging component. The elastic clamping member of the locking component is connected to the first base, and a part of the elastic clamping member protrudes from the hole wall of the limiting hole. A clamping groove is provided on the side surface of the plugging portion of the plugging component, and the plugging portion is located on the center line of the limiting hole. When installing the main screen and the secondary screen, the plugging portion is inserted into the limiting hole, and the plugging portion forces the elastic clamping member to retract in a direction away from the limiting hole, so that the elastic clamping member is clamped in the clamping groove, thereby realizing the quick splicing of the main screen and the secondary screen. When disassembling the main screen and the secondary screen, the plugging portion can force the elastic clamping member to retract in a direction away from the plugging portion, so that the elastic clamping member is disengaged from the clamping groove, thereby realizing the quick separation of the main screen and the secondary screen. In other words, this application can not only achieve quick splicing when installing the main screen and the secondary screen, but also achieve quick separation when disassembling the main screen and the secondary screen. Thus, compared with the existing intelligent blackboard, when installing and disassembling, users need to climb to the top of the intelligent blackboard and lie on the bottom of the device to operate the pull buckle or screws. When installing and disassembling the main screen and the secondary screen of this application, there is no need to climb to the top of the intelligent blackboard and lie on the bottom of the device to operate, and the quick splicing and quick separation of the splicing part of the main screen and the secondary screen can be realized, so that the disassembly and assembly are more convenient and fast, and the installation and disassembly efficiency of the intelligent blackboard is improved.

[0009] Meanwhile, when the plugging portion is inserted into the limiting hole of the locking component, the plugging portion can cooperate with the limiting hole. In this way, the plugging portion and the limiting hole can also play a limiting role on the two display units, so as to limit the movement of the mutually spliced main screen and secondary screen in a direction other than the disassembly and assembly direction, thereby ensuring the splicing stability of the mutually spliced main screen and secondary screen. And, compared with the existing way of separately setting the locking structure and the limiting structure of the intelligent blackboard, the solution of this application is equivalent to integrating the locking structure and the limiting structure into one, reducing the manufacturing cost, and during assembly, there is no need to additionally assemble the limiting structure, and users only need one assembly operation on both the main screen and the secondary screen, simplifying the assembly process and reducing the production cost.

Detailed implementation manners

[0024] To make the objectives, technical solutions, and advantages of this application clearer, the following will further describe the embodiments of this application in detail with reference to the accompanying drawings. Relative spatial position terms used in this application, such as "upper", "above", "lower", "below", "first end", "second end", "one end", "the other end", etc., are used for the purpose of facilitating description to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. The relative spatial position terms may be intended to include different orientations of the device in use or operation other than the orientation shown in the figures. For example, if the device in the figure is flipped, the unit described as being "below" or "beneath" other units or features will be located "above" other units or features. Therefore, the exemplary term "below" can encompass both the upper and lower orientations. The device can be oriented in other ways (rotated 90 degrees or other orientations), and the spatially related descriptive terms used herein can be interpreted accordingly.

[0025] In addition, the terms "installed", "set up", "provided with", "connected", "slidably connected", "fixed", "socketed" should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or there can be internal communication between two devices, components, or parts. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0026] With the rapid development of technology, more and more schools have started to use smart blackboards for teaching, so that teachers can display teaching courseware, videos, audio and other multimedia content on the blackboard, enriching the teaching content and thus improving students' learning interest and comprehension ability.

[0027] A smart blackboard is usually composed of a main screen and a secondary screen spliced together. Considering the large volume of the smart blackboard, it is not convenient to carry and install it as a whole. Therefore, the main screen and the secondary screen of the smart blackboard are mostly disassembled and carried separately. Then, during installation, the main screen and the secondary screen are fixed or hung on the wall through the back, and the main screen and the secondary screen are spliced into one body through splicing devices such as buckles or screws.

[0028] However, the installation positions of existing splicing devices such as buckles or screws are generally at the top or bottom of the rear shell of the smart blackboard. This leads to difficulties in disassembly and assembly, as users need to climb to the top of the smart blackboard and lie on the bottom of the device to operate the buckles or screws.

[0029] In addition, in the process of implementing the present invention, the inventor found that when using a conventional fixed buckle limit structure (such as a hook and a slot) to splice the main screen and the secondary screen, although the main screen and the secondary screen can be quickly spliced and fixed together conveniently, during the disassembly process, the user still needs to climb to the top of the smart blackboard or lie on the bottom of the smart blackboard to separate the hook and the slot for disassembly.

[0030] Therefore, in order to achieve rapid and convenient splicing installation and disassembly of the main screen and the secondary screen at the same time, the applicant proposes a splicing device, which is provided with a locking component and a plugging component. The locking component has the function of elastic limit. During rapid splicing, the plugging component is inserted against the elastic force. During rapid disassembly, the plugging component is pulled out against the elastic force, thereby realizing that the main screen and the secondary screen are very fast and convenient during splicing, installation and disassembly.

[0031] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments of the present application are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0032] Please refer to Figure 1 and Figure 2 As shown, the present application provides a smart blackboard, which at least includes a locking component 100, a plugging component 200, a main screen 300 and a secondary screen 400. Among them, the locking component 100 is installed on the main screen 300, the plugging component 200 is installed on the secondary screen 400, and the installation positions of the locking component 100 and the plugging component 200 correspond to each other. In this way, when installing the main screen 300 and the secondary screen 400, the plugging component 200 can be inserted into the locking component 100, and the locking component 100 automatically elastically locks the plugging component 200, thereby realizing the automatic splicing of the main screen 300 and the secondary screen 400. When disassembling the main screen 300 and the secondary screen 400, the plugging component 200 can overcome the locking force of the locking component 100 and disengage from the locking component 100, thereby realizing the rapid separation of the main screen 300 and the secondary screen 400.

[0033] During the actual installation process, hooks 500 should be installed on the back of the secondary screen 400, and a wall-mounted bracket corresponding to the hooks 500 should be installed on the wall. During installation, the main screen 300 can be fixed or suspended on the wall first. Then, the secondary screen 400 is hung on the suspension bracket through the hooks 500. Finally, the secondary screen 400 is moved closer to the main screen 300 by sliding along the wall-mounted bracket through the hooks 500 until the plug-in component 200 is inserted into the locking component 100, so as to use the locking force between the plug-in component 200 and the locking component 100 to prevent the main screen 300 and the secondary screen 400 from separating, thereby realizing the automatic splicing of the main screen 300 and the secondary screen 400. Correspondingly, during disassembly, the staff can apply force to make the secondary screen 400 slide along the wall-mounted bracket in a direction away from the main screen 300, so that the plug-in component 200 overcomes the locking force of the locking component 100, thereby realizing the automatic separation of the main screen 300 and the secondary screen 400.

[0034] In this embodiment, the main screen 300 is the core display screen of the intelligent blackboard, which is used to display teaching content, courseware, multimedia resources, etc. Teachers can write, mark, and display teaching materials on the main screen 300. At the same time, students can also watch and participate in teaching activities through the main screen 300. The main screen 300 usually has a touch function and can interact with the operations of teachers or students, such as writing, selecting, and dragging by finger or stylus. As an auxiliary display component of the intelligent blackboard, the secondary screen 400 is mainly used to assist teaching, such as displaying information such as the teacher's toolbar, teaching progress, student list, and class schedule. The secondary screen 400 allows teachers to view and manage teaching-related information while performing teaching operations on the main screen 300, improving teaching efficiency. At the same time, the secondary screen 400 can also be used for student interaction and display. For example, students can display their works and answer questions on the secondary screen 400.

[0035] In practical applications, the secondary screen 400 can be a display screen, a blackboard, or a whiteboard, etc., and this application does not make specific limitations. Among them, the number of secondary screens 400 of the intelligent blackboard can be one or two. When there is one secondary screen 400, the secondary screen 400 can be located on one side or below the main screen 300. When there are two secondary screens 400, the two secondary screens 400 can be located on both sides of the main screen 300 respectively.

[0036] Regarding the specific structures of the locking component 100 and the plug-in component 200, please refer to Figure 3 and Figure 4As shown, in an achievable implementation, the locking component 100 may include a first base 110 and an elastic clamping member 120. Among them, the first base 110 is connected to the main screen 300. A limiting hole 111 is provided on one side of the first base 110 close to the plugging component 200. The elastic clamping member 120 is connected to the first base 110, and a part of the elastic clamping member 120 protrudes from the hole wall of the limiting hole 111. The plugging component 200 includes a plugging portion 210. A clamping groove 211 is provided on the side surface of the plugging portion 210. The plugging portion 210 is located on the center line L of the limiting hole 111. When the main screen 300 and the secondary screen 400 are spliced, the plugging portion 210 is inserted into the limiting hole 111, and the plugging portion 210 forces the elastic clamping member 120 to retract in a direction away from the limiting hole 111, so that the elastic clamping member 120 is clamped in the clamping groove 211, thereby realizing the splicing and locking of the main screen 300 and the secondary screen 400. When the main screen 300 and the secondary screen 400 are separated, the plugging portion 210 forces the elastic clamping member 120 to retract in a direction away from the limiting hole 111, so that the elastic clamping member 120 is disengaged from the clamping groove 211, thereby realizing the separation and unlocking of the main screen 300 and the secondary screen 400.

[0037] It is worth mentioning that through the structural settings of the locking component 100 and the plugging component 200 in this application, the main screen 300 and the secondary screen 400 can be quickly spliced during installation and can be quickly separated during disassembly. In this way, compared with the existing intelligent blackboard, when installing and disassembling, users need to climb to the top of the intelligent blackboard and lie on the bottom of the device to operate the pull buckle or screws. In this application, when installing and disassembling the main screen 300 and the secondary screen 400, it is not necessary to climb to the top of the intelligent blackboard and lie on the bottom of the device to operate, and the quick splicing and quick separation of the splicing part of the main screen 300 and the secondary screen 400 can be realized, so that the disassembly and assembly are more convenient and fast, and the installation and disassembly efficiency of the intelligent blackboard is improved.

[0038] In this implementation, the shapes and sizes of the plugging portion 210 and the limiting hole 111 should match, so that when the plugging portion 210 is inserted into the limiting hole 111, the plugging portion 210 can cooperate with the limiting hole 111, thereby playing a limiting role on the spliced main screen 300 and secondary screen 400, restricting the movement of the spliced main screen 300 and secondary screen 400 in directions other than the disassembly and assembly directions, and further ensuring the splicing stability of the spliced main screen 300 and secondary screen 400. And, compared with the existing way of separately setting the locking structure and the limiting structure of the intelligent blackboard, the solution of this application is equivalent to integrating the locking structure and the limiting structure into one, reducing the manufacturing cost, and during assembly, there is no need to additionally assemble the limiting structure, and users only need one assembly operation on both the main screen 300 and the secondary screen 400, simplifying the assembly process and reducing the production cost.

[0039] It should be noted that the elastic card member 120 defined in the present application refers to a component that has elasticity and can perform telescopic activities by utilizing its own elasticity. For the convenience of understanding, the part of the elastic card member 120 used for telescopic activities can be defined as the movable part. The movable part should have a curved surface that protrudes toward the limiting hole 111, and when the inserting part 210 is inserted into the limiting hole 111, the movable part should contact the card slot 211 through this curved surface. In this way, when the main screen 300 and the secondary screen 400 are separated, the movable part is retracted in the direction away from the inserting part 210 under the extrusion action of the inserting part 210 and the guiding action of the curved surface, so as to realize the detachment of the elastic card member 120 from the card slot 211. Of course, the above-mentioned movable part may not have a curved surface that protrudes toward the limiting hole 111. Correspondingly, the side wall and the bottom of the card slot 211 should form a continuous curved surface, and this curved surface is recessed from the periphery of the limiting hole 111 toward the center line L of the inserting part 210. In this way, when the main screen 300 and the secondary screen 400 are separated, the movable part can also be retracted in the direction away from the inserting part 210 under the extrusion action of the inserting part 210 and the guiding action of the curved surface of the card slot 211, so as to realize the detachment of the elastic card member 120 from the card slot 211.

[0040] Regarding the specific structure of the above-mentioned elastic card member 120, the present application provides three implementable embodiments for reference.

[0041] Embodiment 1: As Figure 5 shown, the elastic card member 120 includes an elastic member 121 and a card block 122. A receiving groove 112 is formed on the first base 110. The receiving groove 112 is communicated with the limiting hole 111. The receiving groove 112 extends along a first direction from the hole wall of the limiting hole 111, and the first direction intersects with the center line L. The elastic member 121 and the card block 122 are located in the receiving groove 112. The card block 122 is located at one end of the elastic member 121 close to the limiting hole 111. The card block 122 has an arc surface that protrudes toward the limiting hole 111. When the elastic member 121 is in the initial state, at least part of the arc surface protrudes from the hole wall of the limiting hole 111.

[0042] In this embodiment, during the process of inserting the insertion portion 210 into the limiting hole 111, the clamping block 122 first retracts and gives way in a direction away from the insertion portion 210 under the extrusion of the insertion portion 210 and the guiding of the arc surface. As the card slot 211 moves to directly above the clamping block 122, the acting force of the insertion portion 210 on the top of the clamping block 122 disappears, and the clamping block 122 extends into the card slot 211 under the elastic force of the elastic member 121 to lock the insertion portion 210, thereby realizing the splicing and locking of the two display units. During the process of the insertion portion 210 disengaging from the limiting hole 111, the clamping block 122 retracts again in a direction away from the insertion portion 210 under the extrusion of the insertion portion 210 and the guiding of the arc surface, so that the clamping block 122 disengages from the card slot 211, thereby realizing the unlocking and separation of the two display units.

[0043] In practical applications, the clamping block 122 should be slidably connected in the receiving groove 112, and a limiting portion can be provided at the opening of the receiving groove 112 to block the clamping block 122 by the limiting portion to prevent the clamping block 122 from disengaging from the receiving groove 112. Among them, the elastic member 121 can be a spring or an elastic block with elasticity, etc.

[0044] Embodiment 2: Please refer to Figures 6 to 8 As shown, the elastic clamping member 120 can be a ball screw 123. A threaded hole 113 is formed on the first base 110, and the threaded hole 113 extends along the first direction from the hole wall of the limiting hole 111, and the first direction intersects with the center line L. The ball screw 123 is threadedly connected to the threaded hole 113, and the ball portion of the ball screw 123 protrudes from the hole wall of the limiting hole 111.

[0045] It should be noted that the specific structure of the ball screw 123 can refer to the prior art, and the present application will not elaborate here. However, it can be understood that the top of the ball of the ball screw 123 is usually an arc structure. During the process of inserting the insertion portion 210 into the limiting hole 111, the ball of the ball screw 123 first retracts and gives way in a direction away from the insertion portion 210 under the extrusion of the insertion portion 210 and the guiding of the arc structure at the top of the ball. As the card slot 211 moves to directly above the ball screw 123, the acting force of the insertion portion 210 on the ball of the ball screw 123 disappears, and the ball extends into the card slot 211 under the action of the spring inside the ball screw 123 to lock the insertion portion 210, thereby realizing the splicing and locking of the main screen 300 and the secondary screen 400. During the process of the insertion portion 210 disengaging from the limiting hole 111, the ball of the ball screw 123 retracts again in a direction away from the insertion portion 210 under the extrusion of the insertion portion 210 and the guiding of the arc structure at the top of the ball, so that the ball disengages from the card slot 211, thereby realizing the unlocking and separation of the main screen 300 and the secondary screen 400.

[0046] In practical applications, the threaded hole 113 is a through hole. In this way, during assembly and subsequent maintenance and replacement, the user can disassemble and assemble the bead screw 123 from the outside of the first base 110, and the operation is simpler and more convenient.

[0047] Embodiment 3: As Figure 9 shown, the elastic clamping member 120 can adopt a spring piece 124. A receiving groove 112 is formed on the first base 110. The receiving groove 112 communicates with the limiting hole 111. The receiving groove 112 extends along a first direction from the hole wall of the limiting hole 111, and the first direction intersects the center line L. The spring piece 124 is located in the receiving groove 112. The spring piece 124 has an arc section 1241. The arc section 1241 arches from the receiving groove 112 towards the limiting hole 111, and a part of the arc section 1241 protrudes from the hole wall of the limiting hole 111.

[0048] In this embodiment, during the process of inserting the insertion portion 210 into the limiting hole 111, due to the elasticity of the spring piece 124, the arc section 1241 first deforms and retracts in the direction away from the insertion portion 210 under the extrusion of the insertion portion 210 and the guiding action of the arc surface of the arc section 1241 to make way. As the card slot 211 moves to directly above the arc section 1241, the acting force of the insertion portion 210 on the top of the arc section 1241 disappears, and the arc section 1241 resets and extends into the card slot 211 under the action of its own elastic force to lock the insertion portion 210, thereby realizing the splicing and locking of the main screen 300 and the secondary screen 400. During the process of the insertion portion 210 disengaging from the limiting hole 111, the arc section 1241 deforms and retracts in the direction away from the insertion portion 210 again under the extrusion of the insertion portion 210 and the guiding action of the arc surface of the arc section 1241, so that the arc section 1241 disengages from the card slot 211, thereby realizing the unlocking and separation of the main screen 300 and the secondary screen 400.

[0049] The cross-sectional shape of the above-mentioned insertion portion 210 and the cross-sectional shape of the limiting hole 111 can both be circular, square, oval, triangular, etc. The present application does not make specific limitations in this regard. Taking the cross-sectional shape of the insertion portion 210 and the cross-sectional shape of the limiting hole 111 both being circular as an example, the insertion portion 210 can be generally cylindrical, and the limiting hole 111 is a circular hole. At this time, the above-mentioned center line L coincides with the axis of the limiting hole 111, and the side surface of the above-mentioned insertion portion 210 is the circumferential surface of the insertion portion 210. And considering the easy machinability of the cylinder and the circular hole, the present application preferably uses the insertion portion 210 as a cylinder and the limiting hole 111 as a circular hole, and subsequent descriptions will also be based on this.

[0050] In practical applications, since the elastic card 120 needs to be located on the moving path of the card slot 211 so that the elastic card 120 can be engaged with the card slot 211, thereby realizing the splicing and locking of the main screen 300 and the secondary screen 400. However, the insertion part 210 also needs to be connected to the secondary screen 400 during assembly, which results in relatively high requirements for the machining position accuracy of the card slot 211 and the assembly accuracy between the insertion part 210 and one of the display units. This indirectly increases the production cost of the intelligent blackboard.

[0051] To solve the above problems, in one implementation, please refer to Figure 4 As shown, the card slot 211 can be configured as a complete circular ring groove structure, and the card slot 211 is opened on the circumferential surface of the insertion part 210. That is to say, the card slot 211 is arranged around the circumferential surface of the insertion part 210. In this way, even if there are certain assembly errors and machining errors in the insertion part 210, as the insertion part 210 is inserted into the limit hole 111, the elastic card 120 can also be engaged in the card slot 211, thereby reducing the requirements for the machining accuracy and assembly accuracy of the insertion part 210 and reducing the production cost.

[0052] The elastic card 120 on the first base 110 can be provided with one, two, three, etc. The present application does not specifically limit the specific number of the elastic card 120. Taking the example that three elastic cards 120 are provided on the first base 110, please refer to Figure 8 As shown, the three elastic cards 120 can be arranged in a circular array along the center line L. Preferably, the included angle of the circular feature of the circular array should be 90°, and the telescopic direction of the elastic card 120 in the middle of the three elastic cards 120 is perpendicular to the main screen 300. In other words, one of the three elastic cards 120 is located between the limit hole 111 and the main screen 300, and the other two elastic cards 120 are respectively located on both sides of the limit hole 111. In this way, the thickness of the locking assembly 100 can be made as narrow as possible, and then the thickness of the intelligent blackboard can be made narrow, improving the aesthetics of the intelligent blackboard.

[0053] In a feasible implementation, the insertion assembly 200 further includes a second base 220. The insertion part 210 is connected to the secondary screen 400 through the second base 220, and the insertion part 210 extends from the second base 220 towards the first base 110.

[0054] In this embodiment, locking holes may be respectively formed in the first base 110 and the second base 220, so that the first base 110 is connected to the main screen 300 and the second base 220 is connected to the secondary screen 400 by locking members passing through the locking holes respectively. In practical applications, the insertion part 210 and the second base 220 may be integrally formed by injection molding or casting. Of course, the insertion part 210 and the second base 220 may also be designed separately and then connected into one body by welding, gluing, screw connection or other means.

[0055] In an implementable embodiment, as Figure 1 shown, the first base 110 is located on the back of the main screen 300, and the second base 220 is located on the back of the secondary screen 400. Among them, when the main screen 300 and the secondary screen 400 are in use, the side facing the user is the front of the main screen 300 and the secondary screen 400, and the opposite side is the back of the main screen 300 and the secondary screen 400.

[0056] In another implementable embodiment, as Figure 10 shown, the first base 110 includes a first horizontal section 114 and a first vertical section 115 that are connected to each other. The first horizontal section 114 is attached to the back of the main screen 300, and the first vertical section 115 is located in the frame groove of the main screen 300, and the first vertical section 115 is connected to the frame of the main screen 300 through a first locking member. The second base 220 includes a second horizontal section 221 and a second vertical section 222 that are connected to each other. The second horizontal section 221 is attached to the back of the secondary screen 400, and the second vertical section 222 is located in the frame groove of the secondary screen 400, and the second vertical section 222 is connected to the frame of the secondary screen 400 through a second locking member.

[0057] In this embodiment, part of the thickness of the first base 110 coincides with part of the thickness of the main screen 300, and part of the thickness of the second base 220 coincides with part of the thickness of the secondary screen 400, which can significantly reduce the overall thickness of the smart blackboard and improve the aesthetics of the smart blackboard. At the same time, the first base 110 can also be positioned through the frame groove of the main screen 300. Similarly, the second base 220 can also be positioned through the frame groove of the secondary screen 400, which is convenient for assembly operations.

[0058] In practical applications, the first base 110 should not protrude from the edge of the main screen 300, and the second base 220 should not protrude from the edge of the secondary screen 400, so as to avoid interference between the first base 110 and the second base 220 resulting in a gap difference after the main screen 300 and the secondary screen 400 are spliced.

[0059] In an implementable embodiment, please refer to Figure 3 again and Figure 4As shown, chamfers or rounded corners may be formed at the openings of the limiting holes 111. And / or, chamfers or rounded corners are formed at one end of the insertion part 210 away from the second base 220. In this way, when the insertion part 210 moves towards the limiting hole 111, the insertion part 210 can be inserted into the limiting hole 111 by using the guiding effect of the chamfer / rounded corner, so as to reduce the requirements for the assembly accuracy and processing accuracy of the locking assembly 100 and the insertion assembly 200.

[0060] Based on the same inventive concept, as Figure 11 shown, the present application further provides a display device, which at least includes adjacent first and second display units. A limiting hole 111 is formed on one side of the first display unit close to the second display unit. An elastic clamping member 120 is connected to the first display unit, and a part of the elastic clamping member 120 protrudes from the hole wall of the limiting hole 111. An insertion part 210 is provided on one side of the second display unit close to the first display unit. The insertion part 210 extends from the second display unit towards the first display unit. A clamping groove 211 is formed on the side surface of the insertion part 210. The insertion part 210 is located on the center line of the limiting hole 111. When the first display unit and the second display unit are spliced, the insertion part 210 is inserted into the limiting hole 111, and the insertion part 210 cooperates with the limiting hole 111. The insertion part 210 forces the elastic clamping member 120 to retract in a direction away from the limiting hole 111, so that the elastic clamping member 120 is clamped in the clamping groove 211. When the first display unit and the second display unit are separated, the insertion part 210 forces the elastic clamping member 120 to retract in a direction away from the limiting hole 111, so that the elastic clamping member 120 disengages from the clamping groove 211.

[0061] In this embodiment, it is equivalent to integrating the above-mentioned locking assembly 100 and insertion assembly 200 with the first display unit and the second display unit into one body, without being exposed outside, and performing a hidden setting. At the same time, the overall thickness of the display device is reduced to improve the aesthetics of the display device. In practical applications, the limiting hole 111 can be directly formed on the frame of the first display unit, and the elastic clamping member 120 is connected to the frame of the first display unit. The insertion part 210 is connected to the frame of the second display unit.

[0062] It should be noted that the display device of the present application can be applied to scenarios such as education and teaching, lectures, or other scenarios that require displaying or presenting images to achieve content presentation. Both the first display unit and the second display unit are components for image display or presentation. The first display unit and the second display unit can be two identical or two different display components. In practical applications, the first display unit and the second display unit can be any one of a display screen, a smart screen touch screen, a whiteboard, and a blackboard.

[0063] For the specific structures of the limiting hole 111, the elastic clamping member 120, the insertion portion 210, and the card slot 211, reference can be made to the content described in detail in the above embodiments, and details will not be repeated here.

[0064] Based on the same inventive concept, the present application further provides a splicing device. The splicing device at least includes a locking component 100 and an insertion component 200. The locking component 100 may include a first base 110 and an elastic clamping member 120. Among them, a limiting hole 111 is provided on one side of the first base 110, the elastic clamping member 120 is connected to the first base 110, and a part of the elastic clamping member 120 protrudes from the hole wall of the limiting hole 111. The insertion component 200 includes an insertion portion 210, and a card slot 211 is provided on the side surface of the insertion portion 210. When the insertion portion 210 is inserted into the limiting hole 111, the insertion portion 210 cooperates with the limiting hole 111, and the insertion portion 210 forces the elastic clamping member 120 to retract in a direction away from the limiting hole 111, so that the elastic clamping member 120 is clamped in the card slot 211. When the insertion portion 210 is detached from the limiting hole 111, the insertion portion 210 forces the elastic clamping member 120 to retract in a direction away from the limiting hole 111, so that the elastic clamping member 120 is detached from the card slot 211.

[0065] Further, the elastic clamping member 120 is a beaded screw 123. A threaded hole 113 is provided on the first base 110. The threaded hole 113 extends along a first direction from the hole wall of the limiting hole 111, and the first direction intersects with the center line of the limiting hole 111. The beaded screw 123 is threadedly connected to the threaded hole 113, and the beaded portion of the beaded screw 123 protrudes from the hole wall of the limiting hole 111, so that when the insertion portion 210 is inserted into the limiting hole 111, the bead of the beaded screw 123 is clamped in the card slot 211.

[0066] It should be noted that for the specific structures of the locking component 100 and the insertion component 200, reference can be made to the content described in detail in the above embodiments, and details will not be repeated here. The splicing device is not limited to being applied to display devices, and the splicing device can also be applied to any other two components that need to be quickly disassembled and quickly spliced. For example, the splicing device can be provided between a sweeping robot and a cleaning base station. The locking component 100 can be installed on the cleaning base station, and the insertion component 200 can be installed on the sweeping robot. When the sweeping robot returns to the cleaning base station for operations such as replenishing water or charging, the locking component 100 can automatically lock the insertion component 200 to avoid problems such as movement or shaking of the sweeping robot during operations such as replenishing water or charging.

[0067] It can be seen that in the technical solution provided by the present application, a locking component is installed on the main screen, and a plugging component is installed on the secondary screen. A limiting hole is formed on one side of the first base of the locking component close to the plugging component. The elastic clamping member of the locking component is connected to the first base, and the elastic clamping member partially protrudes from the hole wall of the limiting hole. A clamping groove is formed on the side surface of the plugging portion of the plugging component, and the plugging portion is located on the center line of the limiting hole. When installing the main screen and the secondary screen, the plugging portion is inserted into the limiting hole, and the plugging portion forces the elastic clamping member to retract in a direction away from the limiting hole, so that the elastic clamping member is clamped in the clamping groove, thereby realizing the quick splicing of the main screen and the secondary screen. When disassembling the main screen and the secondary screen, the plugging portion can force the elastic clamping member to retract in a direction away from the plugging portion, so that the elastic clamping member disengages from the clamping groove, thereby realizing the quick separation of the main screen and the secondary screen. In other words, the present application can not only realize quick splicing when installing the main screen and the secondary screen, but also realize quick separation when disassembling the main screen and the secondary screen. Thus, compared with the existing intelligent blackboard, when installing and disassembling, the user needs to climb to the top of the intelligent blackboard and lie on the bottom of the device to operate the pull buckle or screw. When installing and disassembling the main screen and the secondary screen of the present application, there is no need to climb to the top of the intelligent blackboard and lie on the bottom of the device to operate, and the quick splicing and quick separation of the splicing part of the main screen and the secondary screen can be realized, so that the disassembly and assembly are more convenient and fast, and the installation and disassembly efficiency of the intelligent blackboard is improved.

[0068] Meanwhile, when the plugging portion is inserted into the limiting hole of the locking component, the plugging portion can cooperate with the limiting hole. Thus, the plugging portion and the limiting hole can also play a role in limiting the two display units, so as to limit the movement of the mutually spliced main screen and secondary screen in a direction other than the disassembly and assembly direction, thereby ensuring the splicing stability of the mutually spliced main screen and secondary screen. Moreover, compared with the existing intelligent blackboard in which the locking structure and the limiting structure are separately arranged, the solution of the present application is equivalent to integrating the locking structure and the limiting structure into one body, reducing the manufacturing cost. And during assembly, there is no need to additionally assemble the limiting structure. The user only needs to perform one assembly operation on both the main screen and the secondary screen, simplifying the assembly process and reducing the production cost.

[0069] The above are only the preferred embodiments of the present application, and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
