Description

Technical Field

[0001] This invention relates to the field of display technology, and in particular to a display ejection mechanism and a wave-shaped display screen. Background Technology

[0002] Traditional displays (such as advertising screens or exhibition hall displays) are generally flat structures. However, to achieve better visual effects, a wave-shaped display screen has emerged. This type of display screen consists of several extension mechanisms and display units. Each extension mechanism has one display unit. During operation, by controlling the extension mechanisms to extend and retract in a preset manner, the display units can undulate in a similar way. Combined with the images displayed on each screen, this creates a dynamic effect, producing a better visual experience. However, some extension mechanisms, when extending significantly, are prone to tilting downwards at the front due to the weight of the display units, causing the display units to tilt and affecting the display quality. Summary of the Invention

[0003] The main objective of this invention is to provide a display screen ejection mechanism that aims to reduce the risk of the front end tilting downwards when the support cylinder extends.

[0004] To achieve the above objectives, the present invention provides a display screen ejection mechanism comprising:

[0005] The mounting bracket has opposing front and rear plates, the front plate having a first opening;

[0006] A fixing assembly includes a fixing base and a first guide rail, the fixing base being fixed to the rear plate, and the first guide rail being fixed to the fixing base and extending from the rear plate toward the front plate;

[0007] The movable component includes a support cylinder, a mounting plate, and a second guide rail. The support cylinder is sleeved outside the first guide rail and mounted to the first guide rail via a first slider. One end of the support cylinder, away from the fixed base, extends from the first opening and connects to the mounting plate, which is used to mount the display screen. The second guide rail is mounted on the outside of the support cylinder and parallel to the first guide rail. The second guide rail is slidably connected to a second slider located at the edge of the first opening.

[0008] A drive assembly is installed between the fixed base and the support cylinder to drive the support cylinder to move relative to the fixed base.

[0009] Optionally, the first slider is disposed on the upper side wall of the support cylinder, and the second guide rail is disposed on the lower side wall of the support cylinder.

[0010] Optionally, the outer side of the support cylinder is provided with an inwardly recessed mounting groove, the mounting groove extending along the direction from the rear plate to the front plate, and the second guide rail is installed in the mounting groove.

[0011] Optionally, the fixing component includes a connector and at least two first guide rails, with the end of each first guide rail away from the fixing seat connected by the connector, and at least two first sliders are provided inside the support cylinder corresponding to each first guide rail.

[0012] Optionally, the drive assembly includes a drive motor, a drive pulley, a driven pulley, and a transmission belt. The drive motor is mounted on the fixed base and connected to the drive pulley to drive the drive pulley to reciprocate. The driven pulley is rotatably mounted on the connecting member. The transmission belt is sleeved on the drive pulley and the driven pulley. A fixing member is provided inside the support cylinder at a position between the drive pulley and the driven pulley, and the fixing member is fixed to the transmission belt.

[0013] Optionally, the first guide rail and the driven pulley are both located on the side of the connector opposite to the second guide rail, and the driven pulley and the driving pulley are both located between the two first guide rails.

[0014] Optionally, the fixed component, the movable component, and the driving component constitute an ejection module. The front plate has four first openings arranged in a matrix. The mounting bracket has an ejection module corresponding to each of the first openings. The mounting plate has a second opening that communicates with the inner cavity of the support cylinder.

[0015] The present invention also proposes a wave display screen, including a display screen unit and a display screen ejection mechanism as described above, wherein the display screen unit is mounted on a mounting plate of the display screen ejection mechanism.

[0016] Optionally, the display screen ejection mechanism further includes a control device, which includes a processing module, a storage module, and a motor drive module. The storage module, the motor drive module, and the display screen unit are all electrically connected to the processing module. The storage module stores the video to be played and the corresponding motor control program. The processing module executes the motor control program according to the timeline of the video to be played and transmits a first control signal to the motor drive module. The motor drive module controls the drive component in the display screen ejection mechanism to drive the support cylinder to move relative to the fixed seat according to the first control signal.

[0017] Optionally, the display screen ejection mechanism further includes a control device, which includes a processing module, a storage module, a data acquisition module, and a motor drive module. The data acquisition module, the storage module, the motor drive module, and the display screen unit are all electrically connected to the processing module. The storage module stores the video to be played, and the data acquisition module acquires the brightness signal of the video played by the display screen unit in real time. The control device sends a second control signal to the motor drive module according to the video brightness signal and a preset rule. The motor drive module controls the drive component in the display screen ejection mechanism to drive the support cylinder to move relative to the fixed seat according to the second control signal.

[0018] The display screen ejection mechanism of this invention includes a mounting frame, a fixed component, a movable component, and a driving component. The movable component's support cylinder is fitted over the first guide rail of the fixed component. A first slider fixed inside the support cylinder is slidably mounted on the first guide rail. A second guide rail is provided on the outside of the support cylinder, and a second slider is positioned at the edge of the first opening on the front plate of the mounting frame, allowing the second guide rail to slidably mount on the second slider. This placement of the second slider on the front plate supports the support cylinder, allowing the support position to be forward, reducing the cantilever length when the support cylinder extends from the first opening, and mitigating the risk of the front end (the end furthest from the fixed seat) tilting downwards during extension. Simultaneously, the support positions of the first guide rail and the second slider are spaced apart along the length of the first guide rail. Even when the support cylinder is at its maximum extension length, the first guide rail restricts the upward movement of the inner end (the end closest to the fixed seat), further reducing the risk of the front end tilting downwards during extension. This ensures smooth sliding of the movable component and prevents it from "nodding" during extension. Furthermore, the first guide rail is fixed to the mounting bracket, thus avoiding the situation where the first guide rail is too long and increases the overall weight of the movable component. Therefore, the length of the first guide rail can be set according to the actual extension stroke of the support cylinder, and one end of the first guide rail can be extended to the first opening to make the extension stroke of the movable component longer.

[0033] This invention proposes a display screen ejection mechanism.

[0034] In the embodiments of the present invention, please refer to Figures 1 to 7 The display screen ejection mechanism includes a mounting bracket 10, a fixing component 20, a movable component 30, and a drive component 40. The mounting bracket 10 has a front plate 11 and a rear plate 12 facing each other, and the front plate 11 has a first opening 111. The fixing component 20 includes a fixing seat 21 and a first guide rail 22. The fixing seat 21 is fixed to the rear plate 12, and the first guide rail 22 is fixed to the fixing seat 21 and extends from the rear plate 12 toward the front plate 11. The movable component 30 includes a support cylinder 31, a mounting plate 32, and a second guide rail 33. The support cylinder 31 is sleeved on the outside of the first guide rail 22 and is mounted on the first guide rail 22 by a first slider 34. One end of the support cylinder 31 away from the fixing seat 21 extends from the first opening 111 and is connected to the mounting plate 32. The mounting plate 32 is used to mount the display screen. The second guide rail 33 is mounted on the outside of the support cylinder 31 and is parallel to the first guide rail 22. The second guide rail 33 is slidably connected to a second slider 13 located at the edge of the first opening 111. The drive assembly 40 is installed between the fixed base 21 and the support cylinder 31 to drive the support cylinder 31 to move relative to the fixed base 21.

[0035] In this embodiment, the mounting bracket 10 also includes a support structure connecting the front plate 11 and the rear plate 12. The first slider 34 is fixed to the inner side of the support cylinder 31 and slidably mounted on the first guide rail 22. The mounting plate 32 is located on the outer side of the first opening 111, and the mounting plate 32 is approximately perpendicular to the first guide rail 22. The side of the mounting plate 32 facing away from the fixing seat 21 is used to mount the display screen. In use, the second guide rail 33 extends horizontally, and the mounting plate 32, the front plate 11, and the rear plate 12 are all approximately vertically arranged, that is, the support cylinder 31 moves horizontally. The second slider 13 is fixed to the edge of the first opening 111. On the one hand, the second slider 13 can support the support cylinder 31, reducing the risk of the support cylinder 31 tilting. On the other hand, it can avoid the outer side of the support cylinder 31 contacting and rubbing against the edge of the first opening 111. Compared with fixing the first guide rail 22 to the support cylinder 31, the first slider 34 is smaller in size and lighter in weight, which can reduce the overall weight of the moving component 30 and improve the stability of the moving component 30.

[0036] The display screen ejection mechanism of this invention includes a mounting frame 10, a fixing component 20, a movable component 30, and a driving component 40. The movable component 30's support cylinder 31 is fitted over the first guide rail 22 of the fixing component 20. A first slider 34, fixed inside the support cylinder 31, is slidably mounted on the first guide rail 22. A second guide rail 33 is provided on the outside of the support cylinder 31. A second slider 13 is provided at the edge of the first opening 111 of the front plate 11 of the mounting frame 10, allowing the second guide rail 33 to slidably mount on the second slider 13. By providing the second slider 13 at the front plate 11 to support the support cylinder 31, the support position of the support cylinder 31 is positioned forward, reducing the cantilever length of the support cylinder 31 when it extends from the first opening 111, and lowering the risk of the front end (the end furthest from the fixing seat 21) tilting downwards when the support cylinder 31 extends. Simultaneously, the support positions of the first guide rail 22 and the second slider 13 on the support cylinder 31 are spaced apart along the length of the first guide rail 22. Even when the support cylinder 31 is at its maximum extension length, the first guide rail 22 can restrict the upward movement of the inner end of the support cylinder 31 (the end closest to the fixed base 21), thereby reducing the risk of the front end of the support cylinder 31 tilting downward when it extends. This allows the movable component 30 to slide smoothly and avoids the "nodding" situation when the movable component 30 extends. Moreover, since the first guide rail 22 is fixed to the mounting bracket 10, it avoids the situation where the first guide rail 22 is too long and increases the overall weight of the movable component 30. Therefore, the length of the first guide rail 22 can be set according to the actual extension stroke of the support cylinder 31, and one end of the first guide rail 22 can be extended to the first opening 111 to make the extension stroke of the movable component 30 longer.

[0037] In some embodiments, the first slider 34 is disposed on the upper side wall of the support cylinder 31, and the second guide rail 33 is disposed on the lower side wall of the support cylinder 31. Specifically, in use, the first slider 34 is located inside the upper side wall of the support cylinder 31, the second guide rail 33 is located outside the lower side wall, the second slider 13 is located below the second guide rail 33, and the first slider 34 is located above the first guide rail 22. This allows for better contact between the second slider 13 and the second guide rail 33, reducing the risk of deformation of the second slider 13. Of course, in other embodiments, the second slider 13 can also be disposed on the upper side wall of the support cylinder 31, and the first guide rail 22 can be disposed on the lower side wall of the support cylinder 31.

[0038] In some embodiments, the outer side of the support cylinder 31 is provided with an inwardly recessed mounting groove 311, which extends along the rear plate 12 toward the front plate 11, and the second guide rail 33 is installed in the mounting groove 311. Specifically, the portion of the support cylinder 31 corresponding to the mounting groove 311 is raised. In this way, on the one hand, the internal space of the support cylinder 31 can be utilized, avoiding the situation where the second guide rail 33 protrudes from the outer side of the support cylinder 31, which would increase the space occupied by the movable component 30 and improve the structural compactness. On the other hand, the portion forming the mounting groove 311 can act as a reinforcing rib, increasing the rigidity of the support cylinder 31 and reducing the risk of deformation of the support cylinder 31.

[0039] In some embodiments, the fixing component 20 includes a connector 23 and at least two first guide rails 22. The ends of each first guide rail 22 away from the fixing base 21 are connected via the connector 23. At least two first sliders 34 are provided inside the support cylinder 31 corresponding to each first guide rail 22. In this embodiment, there are two first guide rails 22. One end of each first guide rail 22 is fixed to the fixing component 35, and the other end is connected via the connector 23, thus forming an integral structure. This improves the support effect on the movable component 30, making the extension and retraction of the movable component 30 more stable. Of course, in other embodiments, the number of first guide rails 22 can also be one, three, or four, etc.

[0040] In some embodiments, the drive assembly 40 includes a drive motor 41, a drive pulley 42, a driven pulley 43, and a transmission belt 44. The drive motor 41 is mounted on the fixed base 21 and connected to the drive pulley 42 to drive the drive pulley 42 to reciprocate. The driven pulley 43 is rotatably mounted on the connecting member 23. The transmission belt 44 is sleeved on the drive pulley 42 and the driven pulley 43. A fixing member 35 is provided inside the support cylinder 31 and located between the drive pulley 42 and the driven pulley 43. The fixing member 35 is fixed to the transmission belt 44. Specifically, the transmission belt 44 is a synchronous toothed belt. When the drive motor 41 drives the drive pulley 42 to rotate, the drive pulley 42 drives the transmission belt 44 to move. The portion of the transmission belt 44 located between the drive pulley 42 and the driven pulley 43 moves linearly in the direction from the drive pulley 42 to the driven pulley 43, thereby driving the fixing member 35 and the support cylinder 31 to move. By employing a belt drive, the weight of the drive assembly 40 can be reduced, thereby reducing the overall weight of the display screen ejection mechanism. Of course, in other embodiments, the drive assembly 40 may use a linear motor or a rack and pinion system, which converts the rotational motion of the motor into linear motion.

[0041] Optionally, the fixing member 35 is connected between two opposite side walls of the support cylinder 31, that is, both ends of the fixing member 35 are fixed to the two opposite side walls of the support cylinder 31, so that the fixing member 35 can be installed stably. The drive motor 41 can be a servo motor to facilitate the determination of the extension length of the support cylinder 31.

[0042] In some embodiments, the first guide rail 22 and the driven pulley 43 are both located on the side of the connector 23 opposite to the second guide rail 33, and the driven pulley 43 and the driving pulley 42 are both located between the two first guide rails 22. This arrangement allows the support cylinder 31 to be subjected to uniform force when sliding, which can further improve the stability of the moving component 30.

[0043] In some embodiments, the fixed component 20, the movable component 30, and the driving component 40 constitute a push-out module. The front plate 11 has four first openings 111 arranged in a matrix. A push-out module is provided within the mounting frame 10 corresponding to each first opening 111. That is, each push-out module can mount one display screen, and one display screen push-out mechanism can mount four display screens. This simplifies the number of display screen push-out mechanisms and improves assembly efficiency when assembling wave-shaped display screens on-site. Of course, in other embodiments, the front plate 11 has only one first opening 111 or two first openings 111, and a push-out module is provided within the mounting frame 10 corresponding to each first opening 111.

[0044] In some embodiments, the mounting plate 32 is provided with a second opening 321, which communicates with the inner cavity of the support cylinder. This arrangement can reduce the weight of the mounting plate 32, and the heat generated by the display screen mounted on the mounting plate 32 during operation can be dissipated to the support cylinder 31 through the second opening 321, which is beneficial for heat dissipation of the display screen.

[0045] In some embodiments, the fixing base 21 includes a first plate 211, a second plate 212, and two triangular plates 213. The first plate 211 is mounted on the rear plate 12, the two triangular plates 213 are respectively disposed on opposite sides of the first plate 211, the second plate 212 is mounted above the two triangular plates 213 and extends from the first plate 211 toward the front plate 11, and a first guide rail 22 is mounted above the second plate 212. That is, the fixing base 21 is mainly assembled from the separately formed first plate 211, second plate 212, and two triangular plates 213, which facilitates the forming of the first plate 211, second plate 212, and triangular plates 213 and helps to reduce production costs.

[0046] This invention also proposes a wave-shaped display screen, which includes a display screen unit (i.e., the "display screen" mentioned above) and a display screen extension mechanism. The specific structure of the display screen extension mechanism is as described in the above embodiments. Since this wave-shaped display screen adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The display screen unit is mounted on the mounting plate 32 of the display screen extension mechanism. Optionally, the wave-shaped display screen includes multiple display screen extension mechanisms, and each display screen extension mechanism has a display screen unit mounted on its mounting plate 32. All display screen units together form a display screen. In use, the extension and retraction of each active component 30 can be controlled simultaneously with video playback according to a preset method to achieve a stereoscopic display effect.

[0047] In some embodiments, the display ejection mechanism further includes a control device, which includes a processing module, a storage module, and a motor drive module. The storage module, the motor drive module, and the display unit are all electrically connected to the processing module. The storage module stores the video to be played and the corresponding motor control program. The processing module executes the motor control program according to the timeline of the video to be played and transmits a first control signal to the motor drive module. The motor drive module controls the drive component 40 in the display ejection mechanism to drive the support cylinder 31 to move relative to the fixed seat 21 according to the first control signal.

[0048] Specifically, the motor control program is pre-set according to the video to be played, and presets the push-out stroke corresponding to each display unit for the timeline of the video to be played. So when the video is actually played, the execution module can control the video playback and the movement of the display push-out mechanism according to the preset method. This can be customized according to the content of the video to be played to make the display effect better.

[0049] In some embodiments, the control device further includes a data acquisition module electrically connected to the processing module. The data acquisition module acquires the video brightness signal played by the display unit in real time. The control device sends a second control signal to the motor drive module according to the video brightness signal and a preset rule. The motor drive module controls the drive component 40 in the display ejection mechanism to drive the support cylinder 31 to move relative to the fixed seat 21 according to the second control signal. Specifically, the data acquisition module acquires the grayscale value of the video image played by each display unit in real time (when the display unit displays color blocks with multiple grayscale values, the average value is used). The preset rule is the rule between the grayscale value and the ejection stroke of the display unit. For example, when the grayscale value is 255, the drive component 40 drives the support cylinder 31 to extend with the maximum stroke. When the grayscale value is 0, the drive component 40 drives the support cylinder 31 to retract into the mounting bracket 10 (i.e., the extension length of the support cylinder 31 is 0mm). The grayscale value is divided into several levels between 0 and 255, and the support cylinder 31 is set according to different levels. The extension length can be set to 1; or the range of 0 to 255 can be divided into several levels, and the extension length of the support cylinder 31 can be set according to different levels. For example, the range of 0 to 255 can be divided into 15 levels, and the extension length of the support cylinder 31 can be divided into levels 1 to 15 (the extension length of the support cylinder 31 increases sequentially). When the grayscale value is between 0 and 17, the extension length of the support cylinder 31 is level 1; when the grayscale value is between 18 and 34, the extension length of the support cylinder 31 is level 2, and so on. When the grayscale value is between 239 and 255, the extension length of the support cylinder 31 is level 15 (that is, the support cylinder 31 extends at its maximum stroke). With this setting, the wave display screen can automatically control the extension and retraction of the display screen extension mechanism according to the video being played, which is convenient for displaying different videos. Of course, in other embodiments, the support cylinder 31 can also be set to only have a maximum extension state and a state where it is completely retracted within the mounting frame 10.

[0050] When the control device is equipped with a data acquisition module, it can also store the video to be played and the corresponding motor control program through the storage module. The processing module executes the motor control program according to the time axis of the video to be played and transmits the first control signal to the motor drive module. The motor drive module controls the drive component 40 in the display screen ejection mechanism to drive the support cylinder 31 to move relative to the fixed seat 21 according to the first control signal.
