Description

Technical Field

[0001] The present invention relates to the field of display technology, and more particularly, to a display device. Background Art

[0002] At present, in many occasions such as exhibition halls, entertainment venues, monitoring and command centers, it is necessary to use display panels with ultra-large screens to display images. Since the direct production process of ultra-large display panels is very difficult, the existing technology for ultra-large area display devices mostly uses multiple small-size display units to splice displays. Spliced ​​display is a feasible solution to achieve large-size, high-resolution display.

[0003] In practice, the complex assembly and disassembly structure of spliced ​​display devices often requires screen replacement, requiring a large number of personnel, lengthy replacement processes, and significant installation and disassembly difficulties. Furthermore, the relative instability of adjacent spliced ​​screens can cause them to be unevenly aligned or tilted relative to each other, leading to issues such as low overall flatness and poor viewing quality.

[0004] Therefore, it is a technical problem that needs to be urgently solved by those skilled in the art to provide a splicing display device that can not only greatly simplify the disassembly and assembly process, which is conducive to improving the disassembly and assembly efficiency, but also improve the stability between the spliced ​​screens, and has a high level of overall flatness, which is conducive to improving user experience satisfaction. Summary of the Invention

[0005] In view of this, the present invention provides a display device to solve the problems in the prior art of complex disassembly and assembly structure of splicing display devices, a large number of disassembly and assembly personnel required during the disassembly and assembly process, a long replacement time, great difficulty in disassembly and assembly, and poor splicing effect, which affects the viewing effect.

[0006] 14. The swiftly and minutely adjusting device for a wood-planer working table as claimed in claim 1, wherein the first and second ends of the user's manual are connected along the longitudinal direction of the display screen, and the second end of the user's manual is connected along the longitudinal direction of the display screen.

[0007] Compared with the prior art, the display device provided by the present invention achieves at least the following beneficial effects:

[0008] The display device provided by the present invention can be a spliced ​​display device, which includes a frame, a first display module, and a second display module. The first display module and the second display module can be spliced ​​together through the frame to form a large-sized display device. The display device includes a first state, which can be understood as the state after the first display module and the second display module are spliced ​​together. When the display device is spliced ​​from the disassembled state to the first state, the first display module is nested in the second slide groove of the first display module through the first firmware, so that the first display module is fixed to the first frame unit through the first firmware. The support rod in the second slide groove included in the first display module is inserted into the cavity of the first firmware, and the support rod can push out the sliding rod of the first firmware. At this time, due to the stretching effect of the elastic member, although the sliding rod is pushed out of the cavity of the first firmware, it still maintains a state of active connection with the elastic member. After the slide bar is ejected out of the cavity of the first fixture, it can continue to be inserted into the first slot of the second display module along the first direction, thereby allowing the second display module to be spliced ​​and fixed to the first display module through the insertion of the slide bar, which has been ejected out of the cavity of the first fixture, into the first slot. The present invention adopts the above-mentioned splicing assembly structure to form an interlocking structure, which can minimize the gap between the first and second display modules after splicing, increase the stability between the first and second display modules after splicing, and help improve the overall flatness and enhance the viewing experience of the user. In addition, the disassembly between the modules of the display device can be assisted by the rebound force of the elastic member. When the elastic member resets and retracts, it can cause the slide bar to retract into the cavity, enabling the disassembly between the modules of the display device, saving time and effort. The present invention can achieve a splicing effect with a simple structure, is simple to operate, and takes less time, greatly reducing the time required for corresponding adjustments between the display modules. The smooth coordination between the mechanical components can effectively reduce the difficulty of splicing, ensure the splicing effect, and improve assembly efficiency. In addition, the display device utilizes the frame structure to realize the splicing of at least two display modules and the first frame unit at one time. Compared with first splicing the frame unit with a single display module and then splicing the structure formed by the at least two display modules and the frame unit, the step of step-by-step assembly is saved, which can further improve the assembly efficiency.

[0009] Of course, any product implementing the present invention does not necessarily need to achieve all of the above-mentioned technical effects at the same time.

Figure 6 yes Figure 2 A schematic cross-sectional structural diagram of the second slide groove included in the first display module, Figure 7 yes Figure 2 Schematic diagram of the cross-sectional structure of the first chute included in the second display module (it can be understood that in order to clearly illustrate the structure of this embodiment, Figure 1-Figure 5 The display device 000 provided in this embodiment includes: a frame 00, a first display module 10 and a second display module 20;

[0054] The frame 00 comprises at least a first frame unit 001 , which comprises a first fixture 40 , which comprises a cavity 401 , in which a slide bar 403 is movably connected via an elastic member 402 ;

[0055] The first display module 10 includes a second slide groove 101, which extends along a first direction Y. The second slide groove 101 includes a first end 1011 and a second end 1012 that are opposite to each other in the first direction Y. The first end 1011 is connected to the end portion 10L of the first display module 10. The second slide groove 101 includes a support rod 1013, one end of which is fixed to the second end 1012. The support rod 1013 extends along the first direction Y.

[0056] The second display module 20 includes a first slide groove 201 . The first slide groove 201 is a hollow structure, and at least one end of the first slide groove 201 is connected to the end portion 20L of the second display module 20 .

[0057] The display device 000 includes a first state; optionally, the first state can be understood as a state after the first display module 10 and the second display module 20 of the display device are spliced ​​together;

[0058] In the first state, the first fixture 40 is nested in the second slide groove 101 of the first display module 10, the support rod 1013 of the first display module 10 is inserted into the cavity 401 of the first fixture 40, the support rod 1013 of the first display module 10 pushes out the slide rod 403 of the first fixture 40, and the slide rod 403 of the first fixture 40 is inserted into the first slide groove 201 of the second display module 20.

[0059] Specifically, the display device 000 provided in this embodiment can be a spliced ​​display device. The display device 000 includes a frame 00, a first display module 10, and a second display module 20. The first display module 10 and the second display module 20 can be spliced ​​together through the frame 00 to form a large-sized display device 000. Optionally, the first display module 10 and the second display module 20 can both be module structures including display panels. The assembly structure provided on the display module only needs to meet the requirements of not affecting the normal display effect of the display panel. The frame 00 includes at least a first frame unit 001. Optionally, the first frame unit 001 can be designed according to the shape of the first display module 10. For example, if the first display module 10 is a rectangular display module as shown in the figure, the first frame unit 001 can also be a rectangular frame structure. A first fixture 40 is fixedly provided on the first frame unit 001, and the first display module 10 can be mounted on the first frame unit 001 through the first fixture 40. The first fixture 40 has a cavity 401 formed therein. The cavity 401 can be a cavity that passes through the first fixture 40. A slide bar 403 is movably connected to the cavity 401 via an elastic member 402. The slide bar 403 can be extended and retracted in the cavity 401 by the elastic force of the elastic member 402. For example, when the elastic member 402 is stretched under an external force, the slide bar 403 can be extended to the outside of the cavity 401 (e.g., Figure 1 As shown), when the elastic member 402 is reset and retracted, the slide rod 403 can be retracted into the cavity 401. This embodiment is only an example of the structure in which the slide rod 403 is movably connected to the elastic member 402 in the cavity 401. When it is implemented specifically, it includes but is not limited to this and can also be other stretching structures.

[0060] The first display module 10 of this embodiment includes a second slide groove 101. The second slide groove 101 includes a first end 1011 and a second end 1012 opposite to each other in its extension direction, i.e., the first direction Y. The second slide groove 101 at the first end 1011 is connected to the end 10L of the first display module 10. That is, the second slide groove 101 has a structure starting from the end 10L of the first display module 10 and gradually penetrates into the first display module 10 to reach the second end 1012 of the second slide groove 101. The second chute 101 includes a support rod 1013, one end of which is fixed to the second end 1012. The support rod 1013 extends along the first direction Y. The support rod 1013 is a long strip structure with one end fixed to the second end 1012 of the second chute 101. The other end of the support rod 1013 can extend to the end 10L of the first display module 10 without contacting the side wall of the second chute 101. Optionally, the outer diameter of the support rod 1013 is smaller than the inner diameter of the second chute 101, so that a first gap 101K is formed between the support rod 1013 and the side wall of the second chute 101.

[0061] The second display module 20 of this embodiment includes a first slide groove 201. The first slide groove 201 is a hollow structure, and at least one end of the first slide groove 201 is connected to the end 20L of the second display module 20. That is, the first slide groove 201 is a structure that starts at the end 20L of the second display module 20 and gradually penetrates into the second display module 20 to reach the bottom of the first slide groove 201.

[0062] The display device 000 of this embodiment includes a first state, which can be understood as a state in which the first display module 10 and the second display module 20 of the display device are spliced ​​together (e.g., Figure 1 As shown); the display device 000 is from Figure 2 The disassembled state shown is Figure 1 In the first state shown ( Figure 2 The arrows M1 and M2 in the figure indicate the disassembly direction), and the first display module 10 is nested in the second slide groove 101 of the first display module 10 through the first fixture 40, so that the first display module 10 is fixed to the first frame unit 001 of the frame 00 through the first fixture 40. Since there is a first gap 101K between the support rod 1013 in the second slide groove 101 and the side wall of the second slide groove 101, the first fixture 40 can be inserted into the first gap 101K, and the support rod 1013 in the second slide groove 101 included in the first display module 10 is inserted into the cavity 401 of the first fixture 40, and the support rod 1013 can push out the sliding rod 403 of the first fixture 40. At this time, due to the stretching effect of the elastic member 402, although the sliding rod 403 is pushed out of the cavity 401 of the first fixture 40, it still maintains a state of active connection with the elastic member 402 (such as Figure 3After the slide bar 403 is pushed out of the cavity 401 of the first fixture 40, the slide bar 403 can continue to be inserted into the first slide groove 201 of the second display module 20 along the first direction Y, thereby enabling the second display module 20 to be spliced ​​and fixed with the first display module 10 through the insertion of the slide bar 403 pushed out of the cavity 401 of the first fixture 40 into the first slide groove 201, forming a structure as shown in FIG. Figure 1 The splicing module structure shown. This embodiment adopts the above-mentioned splicing assembly structure to form an interlocking structure, which can minimize the gap between the first display module 10 and the second display module 20 after splicing, increase the stability between the first display module 10 and the second display module 20 after splicing, and is conducive to improving the overall flatness and improving the user's viewing effect. In addition, the splicing effect can be achieved by providing a second slide 101 on the first display module 10, providing a first fixture 40 on the frame 00, and providing a first slide 201 on the second display module 10. The operation is simple and time-saving, which greatly reduces the time for corresponding adjustments between the display modules. In addition, the coordination between the mechanical components is smooth, which can effectively reduce the difficulty of splicing, ensure the splicing effect, and improve the assembly efficiency.

[0063] The display device 000 of this embodiment utilizes the structure of the frame 00 to realize the splicing of at least two display modules and the first frame unit 001 at one time. Compared with first splicing the frame unit with a single display module and then splicing the structure formed by the at least two display modules and the frame unit, it saves the step-by-step assembly steps and can further improve the assembly efficiency.

[0064] It should be noted that the figure of this embodiment only illustrates the structure of the first display module 10 and the second display module 20. In specific implementation, the structure of the display module includes but is not limited to this, and may also include other structures that can achieve display effects and assembly effects. This embodiment will not be described in detail here, and the specific understanding can be referred to the structure of the display module in the relevant technology.

[0065] Optional, such as Figure 1-Figure 7 As shown, the display device 000 in this embodiment also includes a second state; when the display device 000 is in the second state, the support rod 1013 of the first display module 10 is pulled out from the cavity 401 of the first fixture 40, the first display module 10 is separated from the first fixture 40, and the sliding rod 403 of the first fixture 40 retracts from the first slide groove 201 of the second display module 20 to the cavity 401 of the first fixture 40, and the second display module 20 is separated from the first fixture 40.

[0066] This embodiment explains that the display device 000 also includes a second state; it can be understood that the second state can be understood as follows Figure 2 The display device 000 is shown in a disassembled state. Figure 1 The first state shown is split into Figure 2 In the second state shown, the support rod 1013 in the first slide groove 101 included in the first display module 10 can be pulled out from the cavity 401 of the first fixture 40 on the first frame unit 001, so that the first display module 10 is separated from the first fixture 40. After the support rod 1013 is pulled out from the cavity 401, under the reset and retraction action of the elastic member 402 connected to the cavity 401 of the first fixture 40, the slide rod 403 of the first fixture 40 can also be pulled back from the first slide groove 201 of the second display module 20 due to the elastic retraction action, and retracted into the cavity 401 of the first fixture 40, thereby separating the second display module 20 from the first fixture 40, completing the process of disassembling and separating the first display module 10 and the second display module 20 from the first frame unit 001. This embodiment adopts the above-mentioned disassembly structure that can be assembled and disassembled. It can not only form an interlocking structure between the first display module 10 and the second display module 20 after splicing, thereby minimizing the gap between the two, increasing the stability between the first display module 10 and the second display module 20 after splicing, improving the overall flatness, and improving the user's viewing effect, but also the disassembly process is simple to operate and time-saving, which is conducive to reducing the time for corresponding adjustments between each display module, and can greatly simplify the disassembly process. In addition, during the assembly and disassembly process, the various structural components cooperate smoothly, which can effectively reduce the difficulty of splicing and disassembly, ensure the splicing effect, and improve the disassembly efficiency.

[0067] Optional, such as Figure 1 and Figure 3 As shown, in this embodiment, the first frame unit 001 includes a crossbar 0011, and the first fixture 40 is fixed on the crossbar 0011; in the first state, the first display module 10 is located on one side of the crossbar 0011, and the second display module 20 is located on the other side of the crossbar 0011.

[0068] This embodiment explains that when the first display module 10 and the second display module 20 are spliced ​​through the frame 00, the first frame unit 001 for accommodating the first display module 10 may include a cross bar 0011, and the cross bar 0011 is used to fix the first fixture 40 included in the first frame unit 001. When the first display module 10 is assembled on the first frame unit 001, along the first direction Y, one end of the first fixture 40 is fixed on the cross bar 0011, and the other end of the first fixture 40 is facing the side away from the cross bar 0011. When the first fixture 40 is fixed to the cross bar 0011, the sliding rod 403 and the elastic member 402 of the first fixture 40 are not fixed to the cross bar 0011, and it is only necessary to ensure that the main body of the first fixture 40 is fixed to the cross bar 0011. Optionally, only part of the end of the first fixture 40 is fixed to the cross bar 0011, exposing the sliding rod 403 and the elastic member 402 of the first fixture 40 so that they can be inserted into the first slide groove 201 of the second display module 20 during splicing. Alternatively, a through hole can be opened on the cross bar 0011 so that the sliding rod 403 and the elastic member 402 of the first fixture 40 can pass through the through hole and be inserted into the first slide groove 201 of the second display module 20. This embodiment does not specifically limit the fixing structure of the first fixture 40 and the cross bar 0011. During specific implementation, the setting can be selected according to actual needs.

[0069] After the first display module 10 is mounted on the first frame unit 001, Figure 3 As shown, the first display module 10 is located on one side of the crossbar 0011. After the first display module 10 and the second display module 20 are spliced ​​together, as shown in FIG. Figure 1 As shown, the second display module 20 is located on the other side of the crossbar 0011 , that is, in the first direction Y, the first display module 10 and the second display module 20 are located on opposite sides of the crossbar 0011 to form a splicing structure of the display device 000 .

[0070] Optionally, when disassembling the first display module 10 and the second display module 20, the support rod 1013 in the second slot 101 of the first display module 10 can be first pulled out from the cavity 401 of the first fixture 40, separating and disassembling the first display module 10 from the first frame unit 001. The elastic member 402 in the first fixture 40 then retracts and pulls back the slide rod 403 in the first slot 201 of the second display module 20. The slide rod 403 is then pulled out of the first slot 201 of the second display module 20, separating and disassembling the second display module 20 from the first frame unit 001, thereby completing the disassembly process of the display device 000. As can be seen from the above, the display device 000 can simplify the assembly and disassembly process by using the first frame unit 001 including the crossbar 0011, thereby ensuring a good splicing effect while also improving assembly and disassembly efficiency.

[0071] It can be understood that the first frame unit 001 of this embodiment includes a cross bar 0011. In specific implementation, the structure of the first frame unit 001 includes but is not limited to this, and may also include other structures. For example, the first frame unit 001 includes a structure other than the cross bar 001 to form a frame that matches the shape of the first display module 10. After the first frame unit 001 and the first display module 10 are assembled, they can be accommodated in the frame structure formed by the first frame unit 001.

[0072] In some optional embodiments, such as Figure 1-Figure 7 As shown, in this embodiment, the elastic member 402 includes a spring, one end 4021 of the spring is connected to the end of the cavity 401 away from the crossbar 0011, and the other end 4022 of the spring is connected to the end of the slide bar 403 toward the crossbar 0011 (as shown in FIG. Figure 2 and Figure 4 shown).

[0073] Optionally, the elastic member 402 may be a spring, and the arrangement structure of the spring and the sliding rod 403 may be an arrangement in which the spring is wound around the periphery of the sliding rod 403 .

[0074] Optionally, in the first state of the display device 000, the elastic member 402 is in a stretched state (eg Figure 1 As shown), in the second state of the display device 000, the elastic member 402 is in a compressed state (as shown Figure 2 As shown), the compressed state can be understood as the original state of the elastic member 402, that is, the spring can be a tension spring, such as Figure 2 and Figure 4 As shown, when the extension spring is not subjected to external load, the coils of the spring are generally tightly connected with no gap or the gap is relatively small; Figure 1 As shown, when the tension spring is subjected to an external force load, such as when the support rod 1013 presses against the slide rod 403, so that the other end 4022 of the spring is driven by the slide rod 403 to leave the cavity 401, a gap is generated between the coils of the spring or the gap is larger than the gap in the original state, so that the spring is in a tensioned state.

[0075] This embodiment explains that the specific structure of the first fixture 40 in which the cavity 401 is movably connected to the slide rod 403 through the elastic member 402 can be that the elastic member 402 includes a spring, and one end 4021 of the spring is connected to the end of the cavity 401 away from the crossbar 0011, such as Figure 4 As shown in the first connection position J1 on the inner wall of the cavity 401, one end 4021 of the spring is fixed to the inner wall of the cavity 401, and the other end 4022 of the spring is connected to the end of the slide bar 403 facing the cross bar 0011, as shown in FIG. Figure 4The other end 4022 of the spring at the second connection position J2 on the slide bar 403 is fixed to the end of the slide bar 403, and the springs at other positions are all arranged to be wound around the periphery of the slide bar 403. The elastic expansion and contraction of the spring can make the slide bar 403 extend and retract in the cavity 401. The original state of the spring provided in this embodiment can be a compressed state, so that when the display device 000 is in the disassembled state in the second state, the compressed spring is retracted in the cavity 401, so that the slide bar 403 is also located in the cavity 401 (as shown in FIG. Figure 4 When the display device 000 enters the first state, that is, the splicing state, as shown in FIG. Figure 1 As shown, the support rod 1013 in the second slide groove 101 of the first display module 10 is inserted into the cavity 401, pushing out the slide rod 403 in the cavity 401. As the support rod 1013 is further inserted, the slide rod 403 is pushed out of the cavity 401. The end of the slide rod 403 drives the other end 4022 of the spring to stretch, so that the entire spring gradually changes to a stretched state. Although the slide rod 403 is pushed out of the cavity 401 of the first fixture 40 and inserted into the first slide groove 201 of the second display module 20, one end 4021 of the spring is still connected to the inner wall of the cavity 401 at the first connection position J1 on the inner wall of the cavity 401, that is, the slide rod 403 can still be movably connected to the inner wall of the cavity 401 through the spring. When the display device 000 is disassembled and returned to the second state, as shown in FIG. Figure 2 As shown, the support rod 1013 is pulled out of the cavity 401, the external force on the sliding rod 403 is released, and the spring returns to its original position and retracts, that is, the other end 4022 of the spring drives the sliding rod 403 to retract into the cavity 401, and the sliding rod 403 is pulled out of the first slide groove 201 of the second display module 20, thereby separating the second display module 20 from the first display module 10. The specific structure of the sliding rod 403 movably connected to the elastic member 402 in the cavity 401 of the first fixture 40 of this embodiment can eliminate the need for other kinetic energy to splice and disassemble the first display module 10 and the second display module 20. It only requires the insertion of the support rod 1013 and the automatic expansion and contraction of the elastic member 402 of the spring structure itself, making the module disassembly process smoother, reducing the difficulty of disassembly for the disassembly personnel, and improving disassembly efficiency.

[0076] In some optional embodiments, please continue to refer to Figure 1-Figure 7 In this embodiment, the first fixing member 40 of the first frame unit 001 includes a main column 400, a cavity 401 is provided in the main column 400, and the first fixing member 40 is fixed to the crossbar 0011 through the main column 400;

[0077] The shape of the main column 400 matches the shape of the second sliding groove 101 .

[0078] This embodiment explains that the structure of the first fixture 40 may include a main column 400, which is the structure of the second slide groove 101 nested in the first display module 10. The shape of the main column 400 matches the shape of the second slide groove 101. For example, if the shape of the main column 400 is cylindrical, the shape of the inner wall of the second slide groove 101 is also cylindrical, thereby achieving the assembly effect of the first display module 10 and the first frame unit 001 in the first state, making the insertion of the first fixture 40 and the second slide groove 101 smoother. A cavity 401 is opened in the main column 400, and the cavity 401 can be a cylindrical groove structure that passes through the main column 400. The first fixture 40 is fixed to the cross bar 0011 through the main column 400. The elastic member 402 and the slide bar 403 set in the cavity 401 of the first fixture 40 can be not fixed to the cross bar 0011 to expose the slide bar 403 and the elastic member 402 of the first fixture 40, so that in the first state of splicing, the slide bar 403 can drive part of the elastic member 402 to be inserted into the first slide groove 201 of the second display module 20, thereby realizing the splicing effect of the first display module 10 and the second display module 20 and improving the splicing stability.

[0079] In some optional embodiments, please continue to refer to Figure 1-Figure 7 In this embodiment, the shape of the sliding rod 403 matches the shape of the cavity structure of the first sliding groove 201, and the length H1 of the sliding rod 403 is equal to the depth H2 of the first sliding groove 201; the shape of the support rod 1013 matches the shape of the cavity 401, and the length H3 of the support rod 1013 is equal to the depth H4 of the cavity 401.

[0080] This embodiment explains that the shape of the cavity structure of the first chute 201 can be a cylindrical groove-like structure. Therefore, the shape of the sliding rod 403 of the first fixture 40 can also be a cylindrical structure. The length H1 of the sliding rod 403 is equal to the depth H2 of the first chute 201. This allows the sliding rod 403 to be smoothly inserted into the first chute 201 of the second display module 20 in the first state, facilitating assembly and disassembly operations. The shape of the support rod 1013 can be a cylindrical structure. Therefore, the shape formed by the inner wall of the cavity 401 of the first fixture 40 can also be cylindrical. The length H3 of the support rod 1013 is equal to the depth H4 of the cavity 401. In the first state, when the support rod 1013 of the first display module 10 pushes out the sliding rod 403 in the cavity 401, it can be smoothly inserted and removed from the channel formed by the inner wall of the cavity 401, facilitating assembly and disassembly operations of the module.

[0081] In some optional embodiments, please continue to refer to Figure 1-Figure 7 In this embodiment, along the length extension direction of the sliding rod 403 , that is, along the first direction Y, the length H1 of the sliding rod 403 is greater than 1 / 3 of the width H5 of the first frame unit 001 .

[0082] This embodiment explains that in the first direction Y, i.e., the length extension direction of the sliding rod 403, the length H1 of the sliding rod 403 included in the first fixture 40 is greater than 1 / 3 of the width H5 of the first frame unit 001. This can avoid the situation where the length H1 of the sliding rod 403 is too short, resulting in the sliding rod 403 being too short when inserted into the first sliding groove 201 of the second display module 20 after the modules are spliced. It can also avoid the situation where the length of the cavity 401 of the first fixture 40 in the first direction Y is too short, affecting the plug-in stability of the first display module 10 and the first fixture 40, thereby making the splicing of the first display module 10 and the second display module 20 more secure.

[0083] In some optional embodiments, please refer to Figures 8-11 , Figure 8 is another structural diagram of a display device provided by an embodiment of the present invention, Figure 9 yes Figure 8 A schematic diagram of the structure of the display device after disassembly, Figure 10 yes Figure 9 A schematic cross-sectional structural diagram of the first fixture included in the first frame unit, Figure 11 yes Figure 9 Schematic diagram of the cross-sectional structure of the first chute included in the second display module (it can be understood that in order to clearly illustrate the structure of this embodiment, Figures 8-10 Transparency is filled in. Figure 9 The arrows M1 and M2 in the figure indicate the disassembly direction. In this embodiment, the end of the slide bar 403 in the first fixture 40 facing the cross bar 0011 includes a first ball plug portion 4031, and the bottom of the first slide groove 201 includes a first spherical groove 2011;

[0084] In the first state, the first spherical groove 2011 of the second display module 20 is engaged with the first ball plug portion 4031 of the first fixture 40 .

[0085] This embodiment explains that the first fixture 40 on the first frame unit 001 can be designed to include a first ball plug portion 4031 at one end of the slide rod 403 facing the cross bar 0011. Optionally, the first ball plug portion 4031 can be a spherical structure, which is provided on the end of the slide rod 403 facing the cross bar 0011. The bottom of the first slide groove 201 includes a first spherical groove 2011 that matches the shape of the first ball plug portion 4031. The bottom of the first slide groove 201 can be understood as the bottom of the slide groove on the side of the first slide groove 201 away from the cross bar 0011 in the first state. Through the shape-matched first ball plug part 4031 and the first spherical groove 2011, in the first state of the display device 000, the sliding rod 403 of the first fixture 40 is pushed out to the outside of the cavity 401 by the support rod 1013 of the first display module 10 and inserted into the first sliding groove 201 of the second display module 20. The first ball plug part 4031 of the first fixture 40 can be engaged with the first spherical groove 2011 of the second display module 20, so that the first ball plug part 4031 is clamped in the first spherical groove 2011, thereby achieving a stable assembly of the sliding rod 403 of the first fixture 40 and the second display module 20, which is beneficial to improving the splicing stability of the first display module 10 and the second display module 20 in the first state, and thereby improving the flatness of the entire device.

[0086] Optional, such as Figure 8 、 Figure 10 and Figure 11 As shown, in this embodiment, the outer diameter D1 of the sliding rod 403 of the first fixture 40 is smaller than the maximum outer diameter D2 of the first ball plug part 4031, and the maximum outer diameter D3 of the first spherical groove 2011 is equal to the maximum outer diameter D2 of the first ball plug part 4031. In this embodiment, the maximum outer diameter D2 of the first ball plug part 4031 at the end of the sliding rod 403 is slightly larger than the outer diameter D1 of the rod body of the sliding rod 403, so that the first ball plug part 4031 can be interference fit with the first spherical groove 2011 at the bottom of the first sliding groove 201. When the first ball plug part 4031 is inserted into the first spherical groove 2011, a certain force is required, which is similar to an interference fit, thereby realizing the clamping of the sliding rod 403 of the first fixture 40 and the second display module 20, which also improves the splicing and stability effect of the first display module 10 and the second display module 20.

[0087] Optional, such as Figure 8 、 Figure 10 and Figure 11As shown, in order to facilitate the sliding rod 403 including the first ball plug part 4031 to slide in the cavity 401, the inner diameter D4 of the cavity 401 in the first fixture 40 can be set to be greater than or equal to the maximum outer diameter D2 of the first ball plug part 4031; and when the sliding rod 403 is pushed out of the cavity 401 by the support rod 1013 of the first display module 10 and inserted into the first slide groove 201 of the second display module 20, in order to facilitate the sliding rod 403 including the first ball plug part 4031 to slide in the first slide groove 201, the inner diameter D5 of the first slide groove 201 can be set to be greater than or equal to the maximum outer diameter D2 of the first ball plug part 4031.

[0088] Optional, such as Figure 8 、 Figure 10 and Figure 11 As shown, in this embodiment, the first spherical groove 2011 opened at the bottom of the second display module 20 may include a first place 20111 and a second place 20112. The second place 20112 is located on the side of the first place 20111 away from the end 20L of the second display module 20. The second place 20112 can be understood as the maximum outer diameter D3 of the first spherical groove 2011. The inner diameter D6 of the first spherical groove 2011 at the first place 20111 is smaller than D3, that is, the first ball plug part 4031 of the sliding rod 403 passes through the first place 20111 with a smaller inner diameter during the process of being inserted into the first spherical groove 2011, and then is completely embedded in the entire first spherical groove 2011, so as to ensure the interference fit effect between the first ball plug part 4031 at the end of the sliding rod 403 and the first spherical groove 2011 of the second display module 20.

[0089] It should be noted that the material of the slide rod 403 included in the first firmware 40 in this embodiment can be a material such as elastic rubber, so that in the second state, when the slide rod 403 retracts into the cavity 401, the elastic material structure of the slide rod 403 itself can facilitate the first ball plug part 4031 of the slide rod 403 to be detached from the first spherical groove 2011, thereby reducing the difficulty of disassembly.

[0090] In some optional embodiments, please refer to Figure 12-15 , Figure 12 is another structural diagram of a display device provided by an embodiment of the present invention, Figure 13 yes Figure 12 A schematic diagram of the structure of the display device after disassembly, Figure 14 yes Figure 13 A schematic cross-sectional structural diagram of the first fixture included in the first frame unit, Figure 15 yes Figure 13 Schematic diagram of the cross-sectional structure of the second chute included in the first display module (it can be understood that in order to clearly illustrate the structure of this embodiment, Figure 12-14 Transparency is filled in. Figure 13The arrows M1 and M2 in the figure indicate the disassembly direction. In this embodiment, the end of the sliding rod 403 in the first fixture 40 away from the crossbar 0011 includes a first spherical cavity 4032.

[0091] At the first end 1011 of the second chute 101 , the end of the support rod 1013 in the second chute 101 includes a second ball plug portion 10131 ;

[0092] In the first state, the second ball plug portion 10131 of the first display module 10 is engaged with the first spherical cavity 4032 of the first fixture 40 .

[0093] This embodiment explains that the first fixture 40 on the first frame unit 001 can be designed as follows Figure 13 In the second state shown, the first fixture 40 includes a sliding rod 403 at one end away from the cross bar 0011, and a first spherical cavity 4032 is provided. Optionally, the first spherical cavity 4032 can be a spherical structure, which is provided on the end of the sliding rod 403 away from the cross bar 0011. The support rod 1012 supports one end of the sliding rod 403, that is, at the first end 1011 of the second chute 101. The end of the support rod 1013 in the second chute 101 includes a second ball plug portion 10131 that matches the shape of the first spherical cavity 4032. A spherical cavity 4032 allows, in the first state of the display device 000, the support rod 1013 presses against the sliding rod 403, and when the sliding rod 403 is pushed out of the cavity 401, the second ball plug portion 10131 of the support rod 1013 can be engaged with the first spherical cavity 4032 of the sliding rod 403, that is, the second ball plug portion 10131 is clamped in the first spherical cavity 4032, thereby realizing a stable assembly of the support rod 1013 of the first display module 10 and the sliding rod 403 of the first fixture 40, which is beneficial to improving the splicing stability of the first display module 10 and the first frame unit 001 in the first state.

[0094] Optional, such as Figure 14 、 Figure 15 and Figure 16 As shown, Figure 16 yes Figure 12A partial enlarged structural diagram after the middle support rod and the sliding rod are engaged. In this embodiment, the maximum outer diameter of the second ball plug part 10131 is L1, and the inner diameter of the first spherical cavity 4032 at the end position of the first fixture 40 is L2; ​​wherein, L1>L2. In this embodiment, the inner diameter of the first spherical cavity 4032 opened at the end of the sliding rod 403 is L2 at the end position of the first fixture 40. The first spherical cavity 4032 may also include a maximum inner diameter L0. The position of the maximum inner diameter L0 is located on the side of the end away from the position of the inner diameter L2 of the first fixture 40. The maximum inner diameter L0 of the first spherical cavity 4032 may be equal to the maximum outer diameter L1 of the second ball plug part 10131, and the maximum outer diameter L1 of the second ball plug part 10131 is set to be greater than L2, so that the support rod When 1013 presses against the slide rod 403, the second ball plug part 10131 needs to pass through the first spherical cavity 4032 with a certain force during the process of inserting the second ball plug part 10131 into the first spherical cavity 4032, which is similar to an interference fit. It first passes through the position of the first spherical cavity 4032 with a smaller inner diameter and an inner diameter of L2, and then is completely embedded in the entire first spherical cavity 4032 to ensure the interference clamping effect of the second ball plug part 10131 at the end of the support rod 1013 and the first spherical cavity 4032 of the slide rod 403.

[0095] It should be noted that the material of the support rod 1013 arranged in the second slide groove 101 in this embodiment can be a material such as elastic rubber, so that in the second state, when the second ball plug part 10131 of the support rod 1013 is pulled out from the first spherical cavity 4032 of the sliding rod 403, the elastic material structure of the support rod 1013 itself can facilitate the detachment of the second ball plug part 10131 of the support rod 1013 from the first spherical cavity 4032, thereby reducing the difficulty of disassembly.

[0096] In some optional embodiments, please refer to Figure 12-16 、 Figure 17 , Figure 17 yes Figure 13 Schematic diagram of a partially enlarged structure of the first firmware (it can be understood that in order to clearly illustrate the structure of this embodiment, Figure 17 In this embodiment, a protrusion structure 404 is provided on the inner wall of the cavity 401 close to the cross bar 0011, and a blocking portion 405 is provided on the end of the cavity 401 away from the cross bar 0011.

[0097] This embodiment explains that when the first fixture 40 is fixed on the cross bar 0011 of the first frame unit 001, the structure of the cavity 401 inside the first fixture 40 for accommodating the elastic member 402 and the sliding rod 403 can be that a protrusion structure 404 is provided on the inner wall thereof close to the end of the cross bar 0011, and a blocking portion 405 is provided on the inner wall of the cavity 401 away from the end of the cross bar 0011. The first ball plug part 4031 of the sliding rod 403 and the protrusion structure 404 provided on the inner wall of the cavity 401 are an interference fit structure. In the process of the sliding rod 403 being pushed out of the cavity 401 by the support rod 1013, that is, in the process of splicing the display module, it is necessary to apply a certain force to make the sliding rod 403 slide along the first direction Y, and the first ball plug part 4031 of the sliding rod 403 passes over the protrusion structure 404 on the inner wall of the cavity 401 and slides out of the cavity 401 in the direction close to the second display module 20; in the process of the sliding rod 403 being pulled back into the cavity 401 by the elastic member 402, that is, in the process of disassembling the display module, the first ball plug part 4031 of the sliding rod 403 passes over the inner wall of the cavity 401 in the reverse direction. The protruding structure 404 on the wall returns to the cavity 401 above the protruding structure 404, which is conducive to ensuring that the sliding rod 403 cannot return to the outside of the cavity 401, and a blocking portion 405 is provided on the inner wall of the cavity 401 away from the end of the cross bar 0011. The blocking portion 405 can limit the sliding rod 403 to prevent it from continuing to ascend and slide out of the cavity 401. Even if the second ball plug portion 10131 of the support rod 1013 is pulled out of the first spherical cavity 4032 of the sliding rod 403 and the two are tightly stuck, the blocking portion 405 can also limit the sliding rod 403 and prevent it from being pulled out of the cavity 401 by the support rod 1013, which is conducive to ensuring the disassembly and assembly effect of the module.

[0098] Optionally, the surface of the protrusion structure 404 in this embodiment is a smooth surface, which helps to apply a certain force to make the slide rod 403 slide along the first direction Y during the process of splicing the display modules. The first ball plug portion 4031 of the slide rod 403 passes over the protrusion structure 404 on the inner wall of the cavity 401 and slides out of the cavity 401 in the direction close to the second display module 20 more smoothly, thereby facilitating the splicing of the modules.

[0099] Optional, such as Figure 15 and Figure 17 As shown, in this embodiment, the maximum outer diameter L1 of the second ball plug portion 10131 on the support rod 1013 is smaller than the inner diameter L3 of the cavity 401 at the position of the blocking portion 405, which can facilitate the smooth separation of the support rod 1013 from the first fixture 40 during the process of pulling out of the cavity 401, thereby facilitating disassembly.

[0100] In this embodiment, Figure 17As shown, the inner diameter L3 of the cavity 401 at the position of the blocking portion 405 is smaller than the outer diameter D1 of the rod body of the slide rod 403. The blocking portion 405 can limit the slide rod 403 and prevent it from being pulled out of the cavity 401 by the support rod 1013, thereby preventing the slide rod 403 from detaching from the cavity 401, which is beneficial to ensuring the disassembly and assembly effect of the module.

[0101] In some optional embodiments, please continue to refer to Figure 1-Figure 7 In this embodiment, the first sliding groove 201 of the second display module 20 includes a third end 20101 and a fourth end 20102 opposite to each other in the first direction Y, and the third end 20101 is connected to the end 20L of the second display module 20;

[0102] In the first state, the first end 1011 of the second slide groove 101 of the first display module 10 and the third end 20101 of the first slide groove 201 of the second display module 20 are arranged opposite to each other, and along the first direction Y, the first end 1011 of the second slide groove 101 of the first display module 10 and the third end 20101 of the first slide groove 201 of the second display module 20 extend along the same straight line.

[0103] This embodiment explains that in the display device 000, the first display module 10 includes a second slide groove 101, the second slide groove 101 extends along the first direction Y, the second slide groove 101 includes a first end 1011 and a second end 1012 opposite to each other in the first direction Y, and the first end 1011 is connected to the end 10L of the first display module 10; the first slide groove 201 of the second display module 20 includes a third end 20101 and a fourth end 20102 opposite to each other in the first direction Y, and the third end 20101 is connected to the end 20L of the second display module 20; after the first display module 10 and the second display module 20 of the display device 000 are spliced ​​together by the first fixture 40 provided on the first frame unit 001, that is, in the first state, The first end 1011 of the second slide groove 101 of the first display module 10 and the third end 20101 of the first slide groove 201 of the second display module 20 are arranged opposite to each other, and along the first direction Y, the first end 1011 of the second slide groove 101 of the first display module 10 and the third end 20101 of the first slide groove 201 of the second display module 20 extend along the same straight line. The position of the second slide groove 101 of the first display module 10 is consistent with the position of the first slide groove 201 of the second display module 20. The support rod 1013 and the sliding rod 403 form a straight line structure inserted into the cavity 401 of the first firmware 40 and the first slide groove 201, which can ensure the stability and flatness of the first display module 10 and the second display module 20 in the spliced ​​state.

In this embodiment, the frame 00 further includes a second frame unit 002, and the second frame unit 002 includes a second fixture, and the second fixture has the same structure as the first fixture 40. It can be understood that since the second fixture has the same structure as the first fixture 40 in this embodiment, in order to clearly distinguish the structure included in the second fixture from the structure included in the first fixture 40 in the future, in this embodiment and subsequent embodiments, the structures included in the first fixture 40 are all denoted by A as a prefix, such as the first fixture A40, the first fixture A40 includes a cavity A401, an elastic member A402, and a sliding rod A403 for distinction, and the structures included in the second fixture are all denoted by B as a prefix, such as the second fixture B40, the second fixture B40 includes a cavity B401, an elastic member B402, and a sliding rod B403, so as to distinguish the first fixture on the first frame unit 001 and the second fixture on the second frame unit 002 by the numbering.

[0108] Since the structure of the second slide groove included in the first display module 10 is the same as the structure of the second slide groove included in the second display module 20, in order to clearly distinguish the structure of the second slide groove included in the second display module 20 from the structure of the second slide groove included in the first display module 10 in subsequent embodiments, in this embodiment and subsequent embodiments, the structure of the second slide groove included in the first display module 10 is indicated by the prefix A. For example, the first display module 10 includes a second slide groove A101, the second slide groove A101 includes a first end A1011 and a second end A1012 opposite to each other in the first direction Y, the first end A1011 is connected to the end 10L of the first display module 10, the second slide groove A101 includes a support rod A1013, and the support rod A1013 is provided in the second slide groove A101. One end of 1013 is fixed to the second end A1012, and the support rod A1013 extends along the first direction Y; the structure of the second slide groove included in the second display module 20 is indicated by a prefix B, such as the second display module 20 includes a second slide groove B101, the second slide groove B101 includes a first end B1011 and a second end B1012 opposite to each other in the first direction Y, the first end B1011 is connected to the end 20L of the second display module 20, the second slide groove B101 includes a support rod B1013, one end of the support rod B1013 is fixed to the second end B1012, and the support rod B1013 extends along the first direction Y, so as to distinguish the second slide groove on the first display module 10 and the second slide groove on the second display module 20 by numbers.

[0109] In the first state of the display device in this embodiment, i.e., the spliced ​​state, the first fixture A40 is nested in the second slot A101 of the first display module 10, the support rod A1013 of the first display module 10 is inserted into the cavity A401 of the first fixture A40, the support rod A1013 of the first display module 10 pushes out the slide bar A403 of the first fixture A40, and the slide bar A403 of the first fixture A40 is inserted into the first slot B201 of the second display module 20. The second fixture B40 is nested in the second slot B101 of the second display module 20, the support rod B1013 of the second display module 20 is inserted into the cavity B401 of the second fixture B40, the support rod B1013 of the second display module 20 pushes out the slide bar B403 of the second fixture B40, and the slide bar B403 of the second fixture B40 is inserted into the first slot A201 of the first display module 10.

[0110] This embodiment explains that the display device 000 includes a first state, which can be understood as a state after the first display module 10 and the second display module 20 of the display device are spliced ​​(eg, Figure 18 As shown); the display device 000 is from Figure 19 The disassembled state shown is Figure 18 In the first state shown, the first display module 10 is fixed to the crossbar 0011 of the first frame unit 001 of the frame 00 through the first fixture A40 by being nested in the second slide groove A101 of the first display module 10. Since there is a first gap A101K between the support rod A1013 in the second slide groove A101 and the side wall of the second slide groove A101, the first fixture A40 can be inserted into the first gap A101K, and the support rod A1013 in the second slide groove A101 included in the first display module 10 is inserted into the cavity A401 of the first fixture A40. The support rod A1013 can push out the sliding rod A403 of the first fixture A40. At this time, due to the stretching effect of the elastic member A402, although the sliding rod A403 is pushed out of the cavity A401 of the first fixture A40, it still maintains a state of active connection with the elastic member A402 (as shown in FIG. 1 ). Figure 18After the sliding rod A403 is ejected to the outside of the cavity A401 of the first fixture A40, the sliding rod A403 can continue to be inserted into the first slide groove B201 of the second display module 20 along the first direction Y, thereby enabling the second display module 20 to be spliced ​​and fixed to the first display module 10 through the insertion of the sliding rod A403 ejected to the outside of the cavity A401 of the first fixture A40 into the first slide groove B201; and at this time, the second display module 20 can be further nested in the second slide groove B101 of the second display module 20 through the second fixture B40, so that the second display module 20 is fixed to the crossbar 0011 of the second frame unit 002 of the frame 00 through the second fixture B40. Since there is a first gap B101K between the support rod B1013 in the second slide groove B101 and the side wall of the second slide groove B101, the second fixture B40 can be inserted into the first gap B101K, and the support rod B1013 in the second slide groove B101 included in the second display module 20 is inserted into the cavity B401 of the second fixture B40, and the support rod B1013 can push out the sliding rod B403 of the second fixture B40. At this time, due to the stretching effect of the elastic member B402, although the sliding rod B403 is pushed out of the cavity B401 of the second fixture B40, it still maintains a state of active connection with the elastic member B402 (such as Figure 18 After the slide bar B403 is pushed out to the outside of the cavity B401 of the second fixture B40, the slide bar B403 can continue to be inserted into the first slide groove A201 of the first display module 10 along the first direction Y, thereby enabling the first display module 10 to be spliced ​​and fixed with the second display module 20 through the insertion of the slide bar B403 pushed out to the outside of the cavity B401 of the second fixture B40 and the first slide groove A201, forming a structure as shown in FIG. Figure 18 The splicing module structure shown.

[0111] This embodiment utilizes the aforementioned splicing assembly structure to minimize the gap between the first and second display modules 10 and 20 after splicing, thereby increasing the stability of the spliced ​​first and second display modules 10 and 20, and thereby improving overall flatness and enhancing the user's viewing experience. Furthermore, the splicing effect can be achieved through a simple structure, such as providing the second chute A101 and the first chute A201 on the first display module 10, installing the first and second fixtures A40 and B40 on the frame 00, and providing the first and second chute B201 and B101 on the second display module 10. This simple operation and time-saving design significantly reduce the time required to adjust the display modules. Furthermore, the smooth coordination between the components effectively reduces the difficulty of splicing, ensuring a good splicing effect while also improving assembly efficiency. Furthermore, the provision of the first and second fixtures A40 and B40 makes the spliced ​​first and second display modules 10 and 20 more stable and secure, further enhancing the stability and flatness of the spliced ​​modules.

[0112] Optional, such as Figures 18-22 As shown, the display device 000 in this embodiment also includes a second state; in the second state, i.e., the disassembled state, the support rod A1013 of the first display module 10 is pulled out of the cavity A401 of the first fixture A40, separating the first display module 10 from the first fixture A40, and the sliding rod A403 of the first fixture A40 retracts from the first slide groove B201 of the second display module 20 into the cavity A401 of the first fixture A40, separating the second display module 20 from the first fixture A40. The support rod B1013 of the second display module 20 is pulled out of the cavity B401 of the second fixture B40, separating the second display module 20 from the second fixture B40, and the sliding rod B403 of the second fixture B40 retracts from the first slide groove A201 of the first display module 10 into the cavity B401 of the second fixture B40, separating the first display module 10 from the second fixture B40.

[0113] This embodiment explains that the display device 000 also includes a second state; it can be understood that the second state can be understood as follows Figure 19 The display device 000 is shown in a disassembled state. Figure 18 The first state shown is split into Figure 19 In the second state shown, the support rod A1013 in the second slide groove A101 included in the first display module 10 can be pulled out from the cavity A401 of the first fixture A40 on the first frame unit 001, so that the first display module 10 is separated from the first fixture A40. After the support rod A1013 is pulled out from the cavity A401, under the reset and retraction action of the elastic member A402 connected to the cavity A401 of the first fixture A40, the slide rod A403 of the first fixture A40 can also be pulled back from the first slide groove B201 of the second display module 20 due to the elastic retraction action, and retracted into the cavity A401 of the first fixture A40, thereby separating the second display module 20 from the first fixture A40. At the same time, the second slide groove B101 included in the second display module 20 is The support rod B1013 is pulled out from the cavity B401 of the second fixture B40 on the second frame unit 002, so that the second display module 20 is separated from the second fixture B40. After the support rod B1013 is pulled out from the cavity B401, under the reset and retraction action of the elastic member B402 connected to the cavity B401 of the second fixture B40, the sliding rod B403 of the second fixture B40 can also be pulled back from the first slide groove A201 of the first display module 10 due to the elastic retraction action, and retracted into the cavity B401 of the second fixture B40, thereby separating the first display module 10 from the second fixture B40, and completing the process of disassembling and separating the first display module 10 from the first frame unit 001 and the second display module 20 from the second frame unit 002.

[0114] This embodiment adopts the above-mentioned disassembly structure that can be assembled and disassembled. It can not only minimize the gap between the first display module 10 and the second display module 20 after splicing, increase the stability between the first display module 10 and the second display module 20 after splicing, improve the overall flatness, and improve the user's viewing effect, but also the disassembly process is simple to operate and time-saving, which is conducive to reducing the time for corresponding adjustments between each display module, and can greatly simplify the disassembly process. In addition, during the assembly and disassembly process, the various components cooperate smoothly, which can effectively reduce the difficulty of splicing and disassembly, ensure the splicing effect, and improve the disassembly efficiency.

[0115] It should be noted that although the first firmware A40 and the second firmware B40 in this embodiment have the same structure, during the splicing process of the first display module 10 and the second display module 20, the directions in which the sliding rods extend are opposite after being pushed out by the support rods, that is, the sliding rod A403 pushed out by the support rod A1013 extends in the direction close to the second display module 20, and the sliding rod B403 pushed out by the support rod B1013 extends in the direction close to the first display module 10, so as to realize the splicing of the first display module 10 and the second display module 20.

[0116] It should be noted that, in this embodiment, along the first direction Y, the cross bar 0011 includes a first side facing the first display module 10 and a second side facing the second display module 20. One end of the first firmware A40 is fixed on the cross bar 0011 on the first side, and the other end of the first firmware A40 faces a side away from the cross bar 0011 and away from the second display module 20. When one end of the first firmware A40 is fixed to the cross bar 0011 on the first side, the sliding rod A403 and the elastic part A402 of the first firmware A40 are not fixed to the cross bar 0011. It is only necessary to ensure that the main body of the first firmware A40 is fixed to the cross bar 0011 on the first side. One end of the second fixture B40 is fixed on the cross bar 0011 on the second side, and the other end of the second fixture B40 is facing the side away from the cross bar 0011 and away from the first display module 10. When one end of the second fixture B40 is fixed to the cross bar 0011 on the second side, the sliding rod B403 and the elastic part B402 of the second fixture B40 are not fixed to the cross bar 0011. It is only necessary to ensure that the main body of the second fixture B40 is fixed to the cross bar 0011 on the second side. Optionally, only part of the end of the first fixture A40 is fixed to the cross bar 0011, exposing the sliding rod A403 and the elastic member A402 of the first fixture A40 so that they can be inserted into the first slide groove B201 of the second display module 20 during splicing. Alternatively, a through hole can be opened on the cross bar 0011 so that the sliding rod A403 and the elastic member A402 of the first fixture A40 can pass through the through hole and be inserted into the first slide groove B201 of the second display module 20. Similarly, only part of the end of the second fixture B40 is fixed to the cross bar 0011, exposing the second fixture B 40, so that they can be inserted into the first slide groove A201 of the first display module 10 during splicing, or a through hole can be opened on the cross bar 0011, so that the sliding rod B403 and the elastic member B402 of the second fixture B40 can pass through the through hole and be inserted into the first slide groove A201 of the first display module 10. This embodiment does not make specific limitations on the fixing structure of the first fixture A40 and the cross bar 0011, and the fixing structure of the second fixture B40 and the cross bar 0011. During specific implementation, the settings can be selected according to actual needs.

The inner wall of the cylindrical groove can facilitate the insertion and removal of the slide rod more smoothly and reduce the resistance to disassembly and assembly. In this embodiment, the second slide groove A101 of the first display module 10 can be a cylindrical slide groove structure that matches the main body of the first firmware A40. The cylindrical inner wall of the groove and the cylindrical main body of the first firmware A40 can facilitate the insertion and removal of the main body of the first firmware A40 in the second slide groove A101. Similarly, the second slide groove B101 of the second display module 10 can be a cylindrical slide groove structure that matches the main body of the second firmware B40. The cylindrical inner wall of the groove and the cylindrical main body of the second firmware B40 can facilitate the insertion and removal of the main body of the second firmware B40 in the second slide groove B101, making the assembly action smoother and helping to reduce the resistance to disassembly and assembly.

Figure 27 (The arrows M1 and M2 in the figure indicate the disassembly direction.) In this embodiment, the first display module 10 includes a plurality of first chutes A201 and a plurality of second chutes A101. Along the longitudinal extension direction X of the crossbar 0011, the first chutes A201 of the first display module 10 are arranged alternately with the second chutes A101 of the first display module 10.

When the display device 000 includes multiple first fixtures A40 and multiple second fixtures B40, the first positions X1 and the second positions X2 are alternately arranged along the longitudinal extension direction X of the crossbar 0011. Since the first slide groove A201 of the first display module 10 and the second slide groove A101 of the first display module 10 are arranged alternately along the length extension direction X of the cross bar 0011, the second firmware B40 corresponding to the first slide groove A201 of the first display module 10 and the first firmware A40 corresponding to the second slide groove A101 of the first display module 10 also need to be arranged alternately along the length extension direction X of the cross bar 0011, so that the first position X1 where the first firmware A40 is connected to the cross bar 0011 and the second position X2 where the second firmware B40 is connected to the cross bar 0011 are not in the same position.

[0136] The third display module 30 includes a fifth slide groove 301 on the side facing the longitudinal rod 0012. The fifth slide groove 301 has the same structure as the first slide groove 201. It can be understood that although the fifth slide groove 301 of this embodiment has the same structure as the first slide groove 201, in order to facilitate the distinction between the first slide groove 201 provided on the second display module 20 and the fifth slide groove 301 provided on the third display module 30, the structure of the fifth slide groove 301 in this embodiment is separately named and numbered, such as Figure 30 and Figure 31 As shown, the fifth slide groove 301 is a cavity structure, and at least one end of the fifth slide groove 301 is connected to the end portion 30L of the third display module 30;

[0137] In the first state, the third fixture 50 is nested in the fourth slot 104 of the first display module 10, the fourth support rod 1043 in the fourth slot 104 is inserted into the third cavity 501 of the third fixture 50, the fourth support rod 1043 in the fourth slot 104 pushes out the third slide bar 503 of the third fixture 50, and the third slide bar 503 of the third fixture 50 is inserted into the fifth slot 301 of the third display module 50;

[0138] In the second state, the fourth support rod 1043 in the fourth slide groove 104 of the first display module 10 is pulled out from the third cavity 501 of the third fixture 50, and the first display module 10 is separated from the third fixture 50. The third slide rod 503 of the third fixture 50 retracts from the fifth slide groove 301 of the third display module 30 into the third cavity 501 of the third fixture 50, and the third display module 30 is separated from the third fixture 50.

[0139] This embodiment explains that the frame 00 also includes a third frame unit 003 and a third display module 30, and the third display module 30 can be further spliced ​​with the first display module 10 and the second display module 20 through the structure of the third frame unit 003 to further expand the display area of ​​the display device 000. Specifically, the display device 000 includes a first state, which can be understood as the state after the first display module 10, the second display module 20, and the third display module 30 of the display device are spliced ​​(such as Figure 30 As shown); the display device 000 is from Figure 31 The disassembled state shown is Figure 30In the first state shown, the first display module 10 is fixed to the first frame unit 001 of the frame 00 by the first fixture 40, by being nested in the second slot 101 of the first display module 10. Since there is a first gap 101K between the support rod 1013 in the second slot 101 and the side wall of the second slot 101, the first fixture 40 can be inserted into the first gap 101K, and the support rod 1013 in the second slot 101 of the first display module 10 is inserted into the cavity 401 of the first fixture 40. The support rod 1013 can push out the sliding rod 403 of the first fixture 40. At this time, due to the tensile effect of the elastic member 402, although the sliding rod 403 is pushed out of the cavity 401 of the first fixture 40, it still maintains a state of active connection with the elastic member 402. After the sliding rod 403 is ejected out of the cavity 401 of the first fixture 40, it can continue to be inserted into the first slot 201 of the second display module 20 along the first direction Y. This allows the second display module 20 to be spliced ​​and fixed to the first display module 10 through the insertion of the sliding rod 403, which has been ejected out of the cavity 401 of the first fixture 40, into the first slot 201. Furthermore, the third fixture 50 is nested in the fourth slot 104 of the first display module 10, further firmly securing the first display module 10 to the first frame unit 001 of the frame 00. Since there is a fourth gap 104K between the fourth support rod 1043 in the fourth slide groove 104 and the side wall of the fourth slide groove 104, the third fixture 50 can be inserted into the fourth gap 104K, and the fourth support rod 1043 in the fourth slide groove 104 included in the first display module 10 is inserted into the third cavity 501 of the third fixture 50. The fourth support rod 1043 can push out the third sliding rod 503 of the third fixture 50. At this time, due to the stretching effect of the third elastic member 502, although the third sliding rod 503 is pushed out of the third cavity 501 of the third fixture 50, it still maintains a state of active connection with the third elastic member 502. After the third slide bar 503 is pushed out to the outside of the third cavity 501 of the third fixture 50, the third slide bar 503 can continue to be inserted into the fifth slide groove 301 of the third display module 30 along the length extension direction X of the cross bar 0011, so that the third display module 30 is spliced ​​and fixed with the first display module 10 through the insertion of the third slide bar 503 pushed out to the outside of the third cavity 501 of the third fixture 50 and the fifth slide groove 301, forming a Figure 30 The splicing module structure shown.

[0150] It can be seen from the above embodiments that the display device provided by the present invention achieves at least the following beneficial effects:

[0151] The display device provided by the present invention can be a spliced ​​display device, which includes a frame, a first display module, and a second display module. The first display module and the second display module can be spliced ​​together through the frame to form a large-sized display device. The display device includes a first state, which can be understood as the state after the first display module and the second display module are spliced ​​together. When the display device is spliced ​​from the disassembled state to the first state, the first display module is nested in the second slide groove of the first display module through the first firmware, so that the first display module is fixed to the first frame unit through the first firmware. The support rod in the second slide groove included in the first display module is inserted into the cavity of the first firmware, and the support rod can push out the sliding rod of the first firmware. At this time, due to the stretching effect of the elastic member, although the sliding rod is pushed out of the cavity of the first firmware, it still maintains a state of active connection with the elastic member. After the slide bar is ejected out of the cavity of the first fixture, it can continue to be inserted into the first slot of the second display module along the first direction, thereby allowing the second display module to be spliced ​​and fixed to the first display module through the insertion of the slide bar, which has been ejected out of the cavity of the first fixture, into the first slot. The present invention adopts the above-mentioned splicing assembly structure to form an interlocking structure, which can minimize the gap between the first and second display modules after splicing, increase the stability between the first and second display modules after splicing, and help improve the overall flatness and enhance the viewing experience of the user. In addition, the disassembly between the modules of the display device can be assisted by the rebound force of the elastic member. When the elastic member resets and retracts, it can cause the slide bar to retract into the cavity, enabling the disassembly between the modules of the display device, saving time and effort. The present invention can achieve a splicing effect with a simple structure, is simple to operate, and takes less time, greatly reducing the time required for corresponding adjustments between the display modules. The smooth coordination between the mechanical components can effectively reduce the difficulty of splicing, ensure the splicing effect, and improve assembly efficiency. In addition, the display device utilizes the frame structure to realize the splicing of at least two display modules and the first frame unit at one time. Compared with first splicing the frame unit with a single display module and then splicing the structure formed by the at least two display modules and the frame unit, the step of step-by-step assembly is saved, which can further improve the assembly efficiency.
