Description

Technical Field

[0001] The invention relates to the technical field of protection of display screen housings, and in particular to an LCD screen with an anti-fall function. Background Art

[0002] LCD screens are made of multiple layers of precision components, including glass substrates, thin-film transistor arrays, color filter layers, and backlight sources. Many of these components are fragile. Once the screen is broken, it will cause display failures, such as bright spots or dark spots caused by pixel damage or affect the uniformity of color display. Repairing or replacing a new screen will be a considerable expense, so it is very necessary to take anti-drop protection measures for LCD screens.

[0003] At present, the anti-fall setting is mostly to set a rubber pad or spring similar to an airbag on the LCD screen shell for buffering. For example, the utility model with the announcement number CN212486963U discloses an LCD display screen with anti-fall function, which includes a display screen, the upper surface of the display screen is movably connected to the left end of the first telescopic rod through a hinge, the other end of the first telescopic rod is fixedly connected to the left side of the protective plate, a movable plate is arranged inside the protective plate, the left side of the first slider and the left side of the inner wall of the first slide groove are respectively fixedly connected to the two ends of the spring, and the right side of the display screen, the left side of the protective plate and the extension plate are all provided with rubber blocks. It buffers the force from the outside on the top of the display screen through the spring, and the impact force from the outside on the left and right sides of the display screen through the rubber block.

[0004] However, when a person falls, an airbag or a rigid rubber pad filled with gas will absorb energy quickly and intensively, which may cause the airbag to rebound quickly or the rubber pad to transfer a large instantaneous stress generated by the rigid impact to the LCD display screen, increasing the risk of damage. When a spring is used for buffering, it may also absorb the initial huge impact energy and then rebound quickly, causing the buffered LCD screen to rebound quickly, resulting in secondary damage when the LCD screen rebounds. To this end, the present invention provides an LCD screen with a fall-proof function. Summary of the invention

[0005] In order to overcome the disadvantage that a hard buffer causes secondary damage to an LCD screen, the present invention provides an LCD screen with an anti-fall function.

[0006] An LCD screen with an anti-fall function comprises a screen shell, wherein the screen shell is fixedly connected with a bracket, the screen shell is fixedly connected with a mounting shell symmetrically distributed along the screen shell, the mounting shell is slidably connected with buffer blocks symmetrically distributed along the mounting shell, the mounting shell is horizontally slidably connected with a longitudinally distributed pressure frame, a longitudinally distributed extrusion airbag is movably arranged on one side of the mounting shell close to the pressure frame, the extrusion airbag corresponds to the pressure frame one-to-one, the pressure frame is extruded and matched with the corresponding extrusion airbag, the buffer block contacts the adjacent extrusion airbag, the mounting shell is movably provided with a longitudinally distributed expansion airbag, the expansion airbag is located between adjacent buffer blocks, a longitudinally distributed connecting shell is fixedly connected with the mounting shell, the extrusion airbag and the expansion airbag are both connected to the adjacent connecting shells with an air guide tube, a pit is opened in the middle of the connecting shell, and a deflation ball valve is movably arranged in the connecting shell.

[0007] According to a further description, a rotating frame is symmetrically distributed along the screen housing, and the rotating frame is rotatably connected to the adjacent mounting housing.

[0008] It is further explained that the rotating frame is connected to the adjacent mounting shell via a rotating rod.

[0009] Further description, it also includes a weight block corresponding to the rotating frame, and the weight block is fixedly connected to the corresponding rotating frame.

[0010] Further description, it also includes a fixing frame symmetrically distributed along the screen shell, the fixing frame is fixed to the back side of the screen shell, and the fixing frame is fixed with an elastic buffer ring.

[0011] It is further explained that the width of the buffer ring decreases gradually in a spiral manner from the innermost ring to the outermost ring.

[0012] It is further explained that the buffer ring is set to be made of metal material for heat conduction and heat dissipation.

[0013] Further description, it also includes connecting blocks symmetrically distributed along the screen shell, the connecting blocks are fixedly connected to the back side of the screen shell, and the connecting blocks are fixedly connected with elastic strips.

[0014] It is further explained that the distance between the elastic strip and the screen housing increases from bottom to top.

[0015] Further description, it also includes a mounting plate frame symmetrically distributed along the screen shell, the mounting plate frame is fixedly connected to a side of the screen shell close to the rotating frame, the mounting plate frame is horizontally slidably connected to a counterweight, the mounting plate frame is horizontally slidably connected to a top block, the top block is extruded and fit with the adjacent counterweight, the top block is extruded and fit with the adjacent rotating frame, and an elastic telescopic component is fixed between the top block and the adjacent mounting plate frame.

[0016] Compared with the prior art, the present invention has the following advantages: the present invention adopts an inflatable airbag for cushioning and cooperates with the method of automatically opening the deflation ball valve to cushion when the LCD screen tilts. Compared with the method of directly using an airbag filled with gas for cushioning, this cushioning method can gradually release gas during the process of the inflated airbag being subjected to force, effectively avoiding a hard landing, thereby managing energy transfer more smoothly, reducing the bottoming rebound effect, further reducing the risk of secondary impact, and maintaining a relatively stable cushioning state.

[0017] The present invention can disperse the instantaneous stress generated during impact by gradually deflating the inflatable airbag, thereby avoiding the generation of dangerous stress peaks. The inflatable airbag will not become too rigid due to over-inflation, thereby better protecting the LCD screen and the supporting structure.

[0018] The present invention makes the tilted LCD screen finally flat by gradually deflation of the inflated airbag, which helps to ensure the stability of its performance and avoid uneven distribution of liquid crystal liquid caused by the tilted LCD screen being in a tilted state for a long time, thereby avoiding affecting its display effect.

[0019] By turning the rotating frame open, the rotating frame can be tilted to firmly support the left and right sides of the LCD screen, thereby enhancing its stability and preventing the LCD screen from tipping over. On the basis of adding weight blocks, the counterweight is pushed forward by the top block, which can balance the overall center of gravity of the screen and prevent the center of gravity from leaning to the rear and causing tipping, thereby reducing the possibility of tipping over.

[0020] The present invention utilizes a buffer ring to smoothly absorb impact force, avoids instantaneous huge reaction force, protects equipment or structures from damage, and the energy absorption distribution is more even during the entire buffering process. Compared with traditional springs that may reach maximum compression at a certain point and rebound instantly, the structure of the buffer ring can maintain the buffering effect for a longer time and improve the buffering efficiency.

[0021] The present invention sets a structure in which the distance between the elastic strip and the LCD screen increases from bottom to top, so that the upper side of the elastic strip lands first, reducing the impact on the upper side of the LCD screen. At the same time, due to the elastic setting of the elastic strip, a progressive buffering effect is achieved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1 To Attachment Fig.14 The technical solution of the present invention is further described.

[0038] Embodiment 1: An LCD screen with anti-fall function, combined with the attached Figure 1 To Attachment Figure 7 , including a screen shell 1, a bracket 11 is fixedly connected to the middle of the bottom of the screen shell 1, a mounting shell 12 is fixedly connected to the screen shell 1 and is symmetrically distributed along the left and right sides of the screen shell 1, the mounting shell 12 is horizontally slidably connected to three groups of buffer blocks 13 symmetrically distributed along the front and rear sides of the mounting shell 12, the front side of the mounting shell 12 is slidably connected to two longitudinally distributed pressing frames 14 along the front and rear directions, and two longitudinally distributed extrusion airbags 15 are movably arranged on one side of the mounting shell 12 near the pressing frame 14, the buffer block 13 contacts the adjacent extrusion airbag 15, the pressing frame 14 is extruded and matched with the adjacent extrusion airbag 15, and the mounting shell 12 is movable Two longitudinally distributed expansion airbags 17 are provided, and the expansion airbags 17 are located between two adjacent buffer blocks 13. Two longitudinally distributed connecting shells 18 are fixedly connected in the mounting shell 12. The connecting shells 18 are hollow, and a pit is opened in the middle of the connecting shells 18. The extrusion airbag 15 and the expansion airbag 17 are connected to the adjacent connecting shells 18 through an air guide pipe 16. A deflation ball valve 19 is movably provided inside the connecting shell 18. When the deflation ball valve 19 is located in the pit, the connecting shell 18 and the adjacent extrusion airbag 15 are not communicated with each other, and the gas remains in the expansion airbag 17, so that the expansion airbag 17 maintains an expanded state.

[0039] When the LCD screen falls forward or backward, the buffer block 13 first contacts the desktop or the ground. At the same time, affected by the tilt, the deflation ball valve 19 rolls away from the recess of the connecting shell 18, so that the connecting shell 18 and the adjacent extrusion airbag 15 are connected to each other. In this way, the buffer block 13 squeezes the expansion airbag 17, so that the gas in the expansion airbag 17 enters the extrusion airbag 15 through the air guide tube 16 and the connecting shell 18, and the extrusion airbag 15 expands and pushes the pressing frame 14 to slide outward.

[0040] When preparing to prop up the overturned LCD screen, first press the pressure frame 14 inward, so that the gas in the squeeze airbag 15 enters the expansion airbag 17 through the air guide tube 16 and the connecting shell 18, so that the expansion airbag 17 recovers the expanded state, and then the LCD screen is propped up to the upright state. At this time, the deflation ball valve 19 automatically rolls into the pit of the connecting shell 18, so that the connecting shell 18 and the adjacent squeeze airbag 15 are not connected, and the gas remains in the expansion airbag 17, so that the expansion airbag 17 maintains the expanded state.

[0041] In summary, first, the present invention adopts the method of using the inflatable airbag 17 for cushioning and cooperates with the automatic opening of the deflation ball valve 19 to cushion when the LCD screen tilts. Compared with the method of directly using an airbag filled with gas for cushioning, this cushioning method can gradually release gas during the force application process of the inflatable airbag 17, effectively avoiding a hard landing, thereby managing energy transfer more smoothly, reducing the bottoming rebound effect, further reducing the risk of secondary impact, and maintaining a relatively stable cushioning state.

[0042] Second, the present invention can disperse the instantaneous stress generated during impact by gradually deflating the inflatable airbag 17 to avoid dangerous stress peaks. The inflatable airbag 17 will not become too rigid due to over-inflation, thereby better protecting the LCD screen and the supporting structure.

[0043] Third, the present invention gradually deflates the inflatable airbag 17 so that the tilted LCD screen is eventually laid flat, which helps to ensure its stable performance and avoid uneven distribution of liquid crystal liquid caused by the tilted LCD screen being in a tilted state for a long time, thereby avoiding affecting its display effect.

[0044] Embodiment 2: Based on embodiment 1, Figure 8 and attached Fig. 9 , and also includes a rotating frame 2 symmetrically distributed along the left and right sides of the screen shell 1. The rotating frame 2 is connected to the adjacent installation shell 12 through a rotating rod 22. A weight block 21 is fixed to the front side of the rotating frame 2 to balance the overall center of gravity of the screen and prevent the center of gravity from leaning to the rear side and tipping over.

[0045] Since the bracket 11 of most LCD screens is located at the front side and the overall center of gravity of the LCD screen is backward, the LCD screen is more likely to tip over to the backward side. In order to prevent this situation, it is necessary to enhance its stability. Specifically, by rotating and opening the turntable 2, the turntable 2 is tilted to provide firm support for the left and right sides of the LCD screen. The weight block 21 can balance the overall center of gravity of the screen, avoid tipping over due to the center of gravity leaning toward the backward side, and reduce the possibility of tipping. When storage is required, the turntable 2 is rotated toward one side of the mounting shell 12, so that the turntable 2 and the weight block 21 are stored.

[0046] Combined with Fig.10, and also includes a fixing frame 3 symmetrically distributed along the left and right sides of the screen shell 1. The fixing frame 3 is fixed to the back side of the screen shell 1. An elastic buffer ring 31 is fixed to the upper part of the fixing frame 3. The width of the buffer ring 31 gradually decreases in a spiral from the innermost circle to the outermost circle, which is used to smoothly absorb the impact force and avoid instantaneous huge reaction force. The buffer ring 31 is set to a metal material for heat conduction and heat dissipation.

[0047] Since the innermost circle of the buffer ring 31 is the widest and thus the most protruding, when the screen tilts backwards, the innermost circle of the buffer ring 31 lands first and gradually expands to the outermost circle to land. This design can provide progressive resistance and achieve progressive buffering, that is, as the compression of the buffer ring 31 deepens, the resistance gradually increases. In this way, the impact force can be absorbed more smoothly, avoiding huge instantaneous reaction force, protecting the equipment or structure from damage, and the energy absorption distribution is more even during the entire buffering process. Compared with traditional springs that may reach maximum compression and rebound instantly at a certain point, the structure of the buffer ring 31 can maintain the buffering effect for a longer time and improve the buffering efficiency.

[0048] Combined with Fig.11 , and also includes connecting blocks 41 symmetrically distributed along the left and right sides of the screen shell 1, the connecting blocks 41 are fixedly connected to the back side of the screen shell 1, and an elastic strip 4 is fixedly connected to the connecting block 41, and the distance between the elastic strip 4 and the screen shell 1 increases from bottom to top.

[0049] When the LCD screen starts to tilt backward, gravity accelerates its downward movement, and the upper part of the LCD screen, which has no support, moves downward first and contacts the desktop or the ground. Therefore, the present invention sets a structure in which the distance between the elastic strip 4 and the LCD screen increases from bottom to top, so that the upper side of the elastic strip 4 lands first, reducing the impact on the upper side of the LCD screen. At the same time, due to the elastic setting of the elastic strip 4, a progressive buffering effect is achieved. When the LCD screen is completely tilted, the LCD screen is completely close to the elastic strip 4.

[0050] Combined with Fig.12 To Attachment Fig.14 , also includes a mounting plate frame 5 symmetrically distributed along the left and right sides of the screen shell 1, the mounting plate frame 5 is fixedly connected to the bottom of the screen shell 1, and a counterweight 51 is slidably connected inside the mounting plate frame 5 along the left and right directions. A top block 52 is slidably connected inside the mounting plate frame 5 along the left and right directions, and the top block 52 is squeezed and matched with the adjacent counterweight 51. When the top block 52 slides toward the side close to the adjacent rotating frame 2, the counterweight 51 is squeezed and slides forward, and the top block 52 is squeezed and matched with the adjacent rotating frame 2. When the rotating frame 2 rotates to contact with the top block 52, the top block 52 is squeezed and slides into the mounting plate frame 5, and an elastic telescopic component 53 is fixedly connected between the top block 52 and the adjacent mounting plate frame 5.

[0051] When the rotating frame 2 is rotated and opened, the rotating frame 2 is separated from the top block 52, and the elastic telescopic component 53 in the compressed state is reset to drive the top block 52 to slide to the side away from the elastic telescopic component 53, and the top block 52 pushes the counterweight 51 forward. In this way, on the basis of the weight block 21, the overall center of gravity of the screen is further balanced to avoid the center of gravity being biased to the rear side and tipping over, thereby further reducing the possibility of tipping over.

[0052] When the rotating frame 2 is received into the mounting shell 12, the rotating frame 2 squeezes the top block 52 to slide toward the side close to the adjacent elastic telescopic component 53, and the elastic telescopic component 53 is compressed. At this time, the counterweight 51 can be pushed backward into the mounting plate frame 5. In this way, the counterweight 51 can be received while the rotating frame 2 is received.

[0053] It should be understood that the above description is only for exemplary purposes and is not meant to limit the present invention. Those skilled in the art will appreciate that variations of the present invention will be included within the scope of the claims herein.
