These drawings and textual descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed implementation manners

[0035] In order to make the objectives, technical solutions, and advantages of the present application clearer, the technical solutions in the present application will be clearly and completely described below in conjunction with the drawings in the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present application.

Rather, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific manner.

[0037] As mentioned in the background art: The display board is usually fixed on the base. After use, the display board can only be stored upright, which is large in volume. When moved back and forth, it is easy to be bumped. The uncovered display board will also accumulate dust, resulting in aging and damage of the display board, affecting the display effect and reducing the service life.

[0038] To solve the above-mentioned technical problems, this application provides a display board. By using a driving component, after the display board body is used, it can be stored in the storage box body, and at the same time, the storage board component covers the display board outlet at the top of the storage box body, achieving the purpose of protecting the display board body. When the display board is moved, it can avoid damage to the display board body after being collided. At the same time, the sealed storage box body can prevent the display board body from getting dusty, and avoid damage caused by dust accumulation after the display board body is stored for a long time, making it difficult to write or display.

[0039] The technical solution of this application and how the technical solution of this application solves the above technical problems will be described in detail below with specific embodiments. These several specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will be described below in conjunction with the drawings.

[0040] As Figure 1-2 shown, a display board provided by an embodiment of this application includes a storage box body 100 and a display board body 200, and is characterized in that it further includes a storage board component 120 and a driving component 300.

[0041] A storage cavity is provided in the storage box body 100, a display board outlet 110 is opened at the top of the storage cavity, the display board body 200 enters and exits the storage cavity through the display board outlet 110, and the driving component 300 is used to drive the display board body 200 and the storage board component 120 to move so that the display board body 200 and the storage board component 120 can be switched between a storage state and a display state.

[0042] Wherein, in the storage state, the display board body 200 is located in the storage cavity of the storage box body 100, and the storage board assembly 120 covers the display board outlet 110; in the display state, the display board body 200 extends out of the storage box body 100 through the display board outlet 110, and the storage board assembly 120 opens the display board outlet 110.

[0043] By using the driving assembly 300, after use, the display board body 200 can be stored in the storage box body 100, and the storage board assembly 120 can also cover the display board outlet 110 at the top of the storage box body 100, achieving the purpose of protecting the display board body 200. When the display board is moved, it can prevent the display board body 200 from being damaged after being collided. At the same time, the sealed storage box body 100 can prevent the display board body 200 from getting dusty, and avoid damage caused by dust accumulation after the display board body 200 is stored for a long time, making it difficult to write or display.

[0044] In some embodiments, the driving assembly 300 includes a display board moving assembly and a driving member 311. The display board moving assembly includes a first threaded rod 312, a first threaded sleeve 313, and a base 314. The first threaded rod 312 is arranged on one side of the storage cavity, the driving member 311 is used to drive the first threaded rod 312 to rotate, the first threaded sleeve 313 is sleeved on the first threaded rod 312, the internal thread of the first threaded sleeve 313 matches the external thread of the first threaded rod 312, the base 314 is fixed on the first threaded sleeve 313, and the display board body 200 is fixed on the top of the base 314.

[0045] In some embodiments, the display board moving assembly further includes a limiting rod 315. The limiting rod 315 is fixed at one end of the storage cavity far from the first threaded rod 312. A sliding sleeve 316 is sleeved on the limiting rod 315, the sliding sleeve 316 is slidably connected with the limiting rod 315, and one end of the base 314 far from the first threaded rod 312 is fixedly connected with the sliding sleeve 316.

[0046] By adopting the above technical solution, when the base 314 rises and falls along the first threaded rod 312, the limiting rod 315 can fix the direction of one end of the base 314 far from the first threaded rod 312 through the sliding sleeve 316, preventing the base 314 from rotating during movement, causing instability of the display board body 200, and avoiding shaking when the display board extends out of the display board outlet 110.

[0047] Such as Figure 3As shown, in some embodiments, the driving assembly 300 also includes a sealing plate moving assembly, which includes a linkage, a second threaded rod 322 and a second threaded sleeve 323. The linkage is used to drive the second threaded rod 322 to rotate. The second threaded rod 322 is arranged at the display board outlet 110 along the long side direction of the display board outlet 110. The second threaded sleeve 323 is sleeved on the second threaded rod 322. The internal thread of the second threaded sleeve 323 matches the external thread of the second threaded rod 322. The second threaded sleeve 323 is fixed with a connecting block 325, and the storage plate assembly 120 is fixedly connected to the connecting block 325.

[0048] The second threaded rod 322 is parallel to the base 314 , so as to ensure the smooth lifting and lowering of the display board body 200 and the smooth opening and closing of the storage board assembly 120 .

[0049] like Figure 4 As shown, in some embodiments, the linkage includes a worm 321 and a worm wheel 324 , the worm 321 is fixed on the top of the first threaded rod 312 , the gear of the worm wheel 324 is meshed with the worm 321 , and the second threaded rod 322 is fixed on the worm wheel 324 .

[0050] By adopting the above technical solution, when the display board body 200 rises and moves from the storage state to the display state, the storage board assembly 120 also moves from the storage state to the display state. The storage board assembly 120 can cooperate with the lifting and lowering of the display board body 200 to timely open or close the display board outlet 110, thereby avoiding the display board body 200 and the storage board assembly 120 being driven separately, resulting in inaccurate cooperation and the display board body 200 being stuck at the display board outlet 110.

[0051] It is understandable that the second threaded rod 322 can be integrally formed with the worm gear 324, and the second threaded rod 322 can also be fixedly connected to the worm gear 324 by bolts. As long as the second threaded rod 322 and the worm gear 324 can be fixed, the present application does not limit the specific connection method between the second threaded rod 322 and the worm gear 324.

[0052] It is understandable that the linkage member can also be a motor, and the second threaded rod 322 is transmission-connected to the linkage member. As long as the linkage member can cooperate with the driving member 311 to work, the present application does not limit the specific structure of the linkage member.

[0053] In some embodiments, there are two storage plate assemblies 120 .

[0054] The second threaded rod 322 includes a first threaded segment 3221 and a second threaded segment 3222 . The first threaded segment 3221 and the second threaded segment 3222 are connected end to end in sequence. The first threaded segment 3221 and the second threaded segment 3222 have opposite threaded directions.

[0055] Two storage board components 120 are oppositely arranged on the top of the storage box body 100 and are slidably connected to the storage box body 100. There are two second threaded sleeves 323, which are respectively sleeved on the first threaded section 3221 and the second threaded section 3222. The connecting blocks 325 on the two second threaded sleeves 323 are fixedly connected to the storage board components 120 correspondingly to drive the two storage board components 120 to move synchronously in the direction of approaching or separating from each other.

[0056] Among them, when the storage board components 120 are in the storage state, the two second threaded sleeves 323 are closest to each other; when the storage board components 120 are in the display state, the two second threaded sleeves 323 are farthest from each other.

[0057] In some embodiments, the storage board component 120 includes a first storage board 121, a second storage board 122 and a rotating shaft 123. The first storage board 121 and the second storage board 122 are rotatably connected through the rotating shaft 123, and the bottom of the first storage board 121 is fixedly connected to the top of the connecting block 325.

[0058] When in the storage state, the two second threaded sleeves 323 approach each other on the first threaded section 3221 and the second threaded section 3222, so that the two first storage boards 121 abut against each other on the top of the display board outlet 110, thereby closing the display board outlet 110; when in the display state, the two second threaded sleeves 323 move away from each other on the first threaded section 3221 and the second threaded section 3222, so that the two first storage boards 121 are located on both sides of the display board outlet 110 to open the display board outlet 110.

[0059] When the storage board component 120 is in the display state, the second storage board 122 can be bent with the first storage board 121 through the rotating shaft 123.

[0060] In some embodiments, the widths of the first storage board 121 and the second storage board 122 are equal to the width of the display board outlet 110.

[0061] The total length of the two storage board components 120 is equal to the length of the display board outlet 110.

[0062] By adopting the above technical solutions, when the storage board component 120 is in the storage state, it is completely stored in the outer contour of the top of the storage box body 100, and at the same time can cover the display board outlet 110, which is not only more beautiful, but also can prevent the storage board component 120 protruding from the display board outlet 110 from being knocked.

[0063] In some embodiments, the first threaded section 3221 and the second threaded section 3222 are of equal length, and the position of the connecting block 325 is symmetric about the connection point of the first threaded section 3221 and the second threaded section 3222, so that the two storage board components 120 can symmetrically open and close the display board outlet 110.

[0064] When the display board body 200 is in the storage state, the storage board assembly 120 is also in the storage state. When the driving member 311 drives the first threaded rod 312 to rotate, the display board body 200 on the base 314 moves from the storage state to the display state. At this time, the worm 321 on the first threaded rod 312 also rotates with the first threaded rod 312, and the first threaded rod 312 drives the worm wheel 324 to rotate, and the second threaded rod 322 on the worm wheel 324 also rotates accordingly. Since the second threaded rod 322 is divided into a first thread segment 3221 and a second thread segment 3222 with opposite thread directions, 22, the two second threaded sleeves 323 are respectively separated from each other on the first threaded segment 3221 and the second threaded segment 3222, and the storage plate assemblies 120 on the second threaded sleeves 323 are also separated from each other, gradually exposing the display board outlet 110; when the rotating shafts 123 on the two storage plate assemblies 120 exceed the top range of the storage box body 100, the second storage plate 122 is folded downward by gravity until the display board body 200 extends out of the display board outlet 110, the display board body 200 reaches the display state, the storage plate assembly 120 stops moving, and the storage plate assembly 120 reaches the display state position.

[0065] On the contrary, when the display board body 200 is in the display state position, the storage board assembly 120 is also in the display state position. When the driving member 311 drives the first threaded rod 312 to rotate, the display board body 200 on the base 314 moves from the display state to the storage state. At this time, the worm 321 on the first threaded rod 312 also rotates with the first threaded rod 312, and the first threaded rod 312 drives the worm wheel 324 to rotate, and the second threaded rod 322 on the worm wheel 324 also rotates accordingly. The two second threaded sleeves 323 are respectively The first thread segment 3221 and the second thread segment 3222 approach each other, and the storage plate assembly 120 on the second threaded sleeve 323 also approaches each other, gradually closing the display board outlet 110; when the rotating shafts 123 on the two storage plate assemblies 120 are within the range of the display board outlet 110, the second storage plate 122 rises along the edge of the display board outlet 110 until it is flush with the first storage plate 121, and the display board body 200 reaches the storage state position, and the storage plate assembly 120 stops moving and reaches the storage state position.

[0066] In some embodiments, the sealing plate moving assembly further includes a guide rod 326 , the guide rod 326 is parallel to the second threaded rod 322 , and the connecting block 325 is slidably connected to the guide rod 326 .

[0067] The guide rod 326 is parallel to the second threaded rod 322 .

[0068] By adopting the above technical solution, the guide rod 326 can limit the second threaded sleeve 323 to prevent the first threaded sleeve 313 from rotating when sliding on the second threaded rod 322, causing the storage plate assembly 120 to move and deviate.

[0069] In some embodiments, the driving member 311 is a motor, and the first threaded rod 312 is drivingly connected to the output end of the driving member 311.

[0070] Wherein, the driving member 311 can rotate forward or backward.

[0071] When the driving member 311 rotates forward, it drives the first threaded rod 312 to rotate. Since the base 314 cannot rotate within the storage box 100, the base 314 rises along the thread of the first threaded rod 312, and the display board body 200 rises from the storage state to the display state; when the driving member 311 rotates backward, the display board body 200 descends from the display state to the storage state.

[0072] It can be understood that when the driving member 311 rotates forward, the display board body 200 can also move from the display state to the storage state; when the driving member 311 rotates backward, since the base 314 cannot rotate within the storage box 100, the base 314 rises along the thread of the first threaded rod 312, and the display board body 200 rises from the storage state position to the state position.

[0073] In some embodiments, the driving member 311 is a manual rocker, and the first threaded rod 312 can be rotated by manual rotation.

[0074] It can be understood that as long as the driving member 311 can control the first threaded rod 312 to rotate, the specific structure of the driving member 311 is not limited in this application.

[0075] In some embodiments, the length of the first storage board 121 is less than the length of the second storage board 122.

[0076] By adopting the above technical solution, after the second storage board 122 is bent relative to the first storage board 121, the volume of the part of the first storage board 121 exceeding the display board outlet 110 is reduced, and more of the second storage board 122 is stored on both sides of the storage box 100, making it more beautiful.

[0077] In some embodiments, a remote controller 400 and a label bag 500 are attached to the outer surface of the storage box 100. The remote controller 400 is used to remotely control the opening and closing of the driving member 311; by setting the remote controller 400, it is convenient to control the start and stop of the driving member 311. By setting the label bag 500, it is convenient to draw a note from the label bag 500 for display when using the display board body 200.

[0078] In some embodiments, universal wheels 600 are fixedly installed at the bottom of the storage box 100.

[0079] Among them, four universal wheels 600 are symmetrically installed.

[0080] The display board can be conveniently moved by installing universal wheels 600.

[0081] This application can be applied to the scenario of project management progress tracking and display: taking the case where when the driving member 311 rotates forward, the display board body 200 moves from the storage state to the display state, and the storage board assembly 120 gradually moves from the storage state to the display state as an example.

[0082] When the display board needs to be used, when the driving member 311 rotates forward, the driving member 311 drives the first threaded rod 312 to rotate, and the base 314 rises along the thread of the first threaded rod 312. Under the guiding action of the limiting rod 315 on the sliding sleeve 316, the end of the base 314 connected to the sliding sleeve 316 slides upward along the sliding sleeve 316, and the display board body 200 gradually rises and moves from the storage state to the display state.

[0083] At the same time, the worm 321 rotates with the first threaded rod 312, the first threaded rod 312 drives the worm wheel 324 to rotate, and the second threaded rod 322 on the worm wheel 324 also rotates accordingly. The two second threaded sleeves 323 move away from each other on the first threaded section 3221 and the second threaded section 3222 respectively, and the storage board assemblies 120 fixedly connected to the second threaded sleeves 323 also move away from each other, gradually exposing the display board outlet 110.

[0084] When the rotating shafts 123 on the two storage board assemblies 120 exceed the top range of the storage box 100, the second storage board 122 folds downward under the action of gravity until the display board body 200 extends out of the display board outlet 110, the display board body 200 reaches the display state position, and the storage board assembly 120 reaches the display state position. At this time, information such as task completion status, milestone achievement status, and resource allocation status can be displayed using the display board. Labels in the label bag 500 are used to assist in marking the to-do, in-progress, or completed status of the project progress on the display board body 200, helping team members and stakeholders understand the latest situation of the project and promoting communication and decision-making.

[0085] When the display board is no longer used, the driving member 311 rotates in the reverse direction, the base 314 rises along the thread of the first threaded rod 312. Under the guiding action of the limiting rod 315 on the sliding sleeve 316, the end of the base 314 connected to the sliding sleeve 316 slides downward along the sliding sleeve 316, and the display board body 200 gradually descends and moves from the display state to the storage state.

[0086] Meanwhile, the worm 321 rotates with the first threaded rod 312. The first threaded rod 312 drives the worm gear 324 to rotate, and the second threaded rod 322 on the worm gear 324 also rotates accordingly. The two second threaded sleeves 323 approach each other on the first threaded section 3221 and the second threaded section 3222 respectively, and the storage plate assemblies 120 on the second threaded sleeves 323 also approach each other, gradually closing the display board outlet 110. When the rotating shafts 123 on the two storage plate assemblies 120 are within the range of the display board outlet 110, the second storage plate 122 warps along the edge of the display board outlet 110 until it is flush with the first storage plate 121. The display board body 200 reaches the position in the storage state, and the storage plate assemblies 120 stop moving and reach the display state. At this time, the display board body 200 is inside the storage box 100, and the display board outlet 110 at the top of the storage box 100 is covered by the storage plate assemblies 120. The display board has a smaller volume, and the display board body 200 will not be exposed outside the storage box 100 and be bumped, and the display board body 200 will not be eroded by dust and water vapor.

[0087] This application can be applied to the scenario of project management progress tracking and display. After the display board body 200 is used, it can be stored in the storage box 100, and the storage plate assemblies 120 can cover the display board outlet 110 at the top of the storage box 100, so as to achieve the purpose of protecting the display board body 200. When the display board is moved, it can avoid damage to the display board body 200 after being collided. At the same time, the sealed storage box 100 can prevent the display board body 200 from getting dusty and avoid damage caused by dust accumulation after the display board body 200 is stored for a long time, making it difficult to write or display.
