Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to a corner protection structure and a display screen. Background Technology

[0002] Currently, LED displays typically consist of a frame and display modules, with the display modules mounted on the frame. To protect the four corners of the display from external impacts and collisions, and to reduce the risk of damage caused by drops, scratches, etc., corner protectors are usually installed at the four corners. This mitigates the impact of external forces on the display, reduces the likelihood of breakage, and especially lowers the possibility of damage to the display modules.

[0003] However, existing corner protection structures are usually quite complex and expensive, which indirectly increases the cost of the display screen. Utility Model Content

It should be understood that the specific embodiments described herein are merely illustrative of the application and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present application, not the entire structure.

[0049] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0050] Figure 1 This is a schematic diagram illustrating the usage state of the corner protection structure provided in the embodiments of this application, such as... Figure 1 As shown.

[0051] This application provides a corner protection structure 100, including: a fixing plate 10, a guard plate 20 and a hinge assembly 30, wherein the hinge assembly 30 is hinged to the fixing plate 10 and the guard plate 20 respectively.

[0052] Among them, the guard plate 20 can move relative to the fixed plate 10 between a first position and a second position. When it is in the first position (e.g. Figure 1 As shown, when the guard plate 20 is in the first position relative to the fixed plate 10, the guard plate 20 is spaced apart from the fixed plate 10 by a predetermined distance, and the hinge assembly 30 locks the guard plate 20 in the current position; when in the second position, the guard plate 20 abuts against the fixed plate 10.

[0053] Combination Figure 1 See Figure 2 The corner protection structure 100 provided in this application embodiment can be applied to a display screen, including but not limited to a screen body 200 and a corner protection structure 100. The screen body 200 includes a frame and a screen body. The frame can be a rectangular frame. The corner protection structure 100 can be set in the four corner areas of the frame, or it can be set in other positions according to different needs. The connection method between the corner protection structure 100 and the frame includes but is not limited to the corner protection structure 100 being fixedly connected to the frame by screws through a fixing plate 10. Based on the hinge assembly 30 being hinged to the fixing plate 10 and the guard plate 20 respectively, the guard plate 20 can move relative to the fixing plate 10 between a first position and a second position.

[0054] When the display screen is used alone, the hinge assembly 30 is in a pop-up state, supporting the protective plate 20 at a certain height, so that the protective plate 20 is spaced apart from the fixed plate 10 by a predetermined distance. This predetermined distance includes, but is not limited to, the height of the hinge assembly 30 relative to the fixed plate 10. At this time, the protective plate 20 is in a first position relative to the fixed plate 10 (e.g., Figure 1As shown, the protective plate 20 is in the first position relative to the fixed plate 10, while the hinge assembly 30 locks the protective plate 20 in its current position. In this state, the protective plate 20 also protrudes from the surface of the frame, or extends beyond the surface of the screen body 200. When the four corners of the display screen are subjected to external impact and collision, they will first collide with the corner protection structure 100. The corner protection structure 100 can effectively protect the four corners of the display screen from external impact and collision, reducing the risk of damage caused by drops, scratches, etc., and in particular, preventing damage to the LEDs on the display screen.

[0055] When two displays need to be used together, the protective plate 20 can be placed along... Figure 1 When the dashed arrow in the diagram moves to the second position, and the guard plate 20 is in the second position, the guard plate 20 abuts against the fixing plate 10. At this time, the hinge assembly 30 is in a folded state, and the guard plate 20 is lowered from a predetermined distance from the fixing plate 10 to abutting against it. That is, the height of the guard plate 20 is reduced so that the guard plate 20 is approximately flush with the surface of the frame. This prevents the guard plate 20 from affecting the splicing of the two displays, allowing the two displays to be spliced ​​and reducing the gap between the two displays after splicing.

[0056] Furthermore, to better achieve flush alignment between the guard plate 20 and the frame surface, a receiving groove 201 can be provided on the frame, and the corner guard structure 100 can be provided within the receiving groove 201. When the guard plate 20 is in the first position relative to the fixed plate 10, the guard plate 20 extends out of the receiving groove 201, thereby making the guard plate 20 protrude relatively from the surface of the frame. When the guard plate 20 is in the second position relative to the fixed plate 10, the guard plate 20 retracts into the receiving groove 201 or moves to the opening of the receiving groove 201, thereby making the guard plate 20 approximately flush with the surface of the frame.

[0057] The technical solution provided in this application embodiment allows the corner protection structure 100 to be applied to the corners of the display screen, thereby protecting the display screen, mitigating the impact of external forces on the display screen, reducing the risk of display screen breakage, and especially effectively preventing damage to the LED beads on the display screen. At the same time, since the protective plate 20 can switch between the first and second positions relative to the fixed plate 10, it will not affect the splicing of the two display screens. Furthermore, the corner protection structure 100 has a simple overall structure and low cost, which indirectly reduces the manufacturing cost of the display screen. It also features stable structure, simple operation, and strong practicality.

[0058] The technical solutions provided in the embodiments of this application will be described in further detail below.

[0059] Combination Figure 1 See Figure 3 and Figure 4In one embodiment of this application, the fixing plate 10 may include a first base plate 11 and two first side plates 12. The two first side plates 12 are disposed on opposite sides of the first base plate 11, and are respectively hinged to the hinge assembly 30. The fixing plate 10 can be connected to the frame through the first base plate 11. For example, corresponding mounting holes are provided on the first base plate 11 and the frame, and fasteners such as screws can be used to connect the first base plate 11 and the frame through the mounting holes. The two first side plates 12 extend toward the direction of the guard plate 20 and are hinged to the hinge assembly 30, which can better realize the connection between the fixing plate 10 and the hinge assembly 30, making the connection more stable. In one possible embodiment of this application, the hinge assembly 30 is located between the two first side plates 12 and is hinged to the two first side plates 12 respectively.

[0060] Accordingly, to ensure the connection stability between the hinge assembly 30 and the guard plate 20, in one embodiment of this application, the guard plate 20 includes a second base plate 21 and two second side plates 22. The two second side plates 22 are disposed on opposite sides of the second base plate 21, and are respectively hinged to the hinge assembly 30. The two second side plates 22 extend towards the direction of the fixed plate 10, and are hinged to the hinge assembly 30 through the two second side plates 22, which can better achieve the connection between the guard plate 20 and the hinge assembly 30, making the connection more stable. In one possible embodiment of this application, the hinge assembly 30 is located between the two second side plates 22 and is hinged to each of the two second side plates 22.

[0061] Further, see also Figure 3 and Figure 4 In some feasible embodiments of this application, an extension plate 23 is further provided on the second base plate 21; when the guard plate 20 is in the first position, the extension plate 23 extends beyond the fixing plate 10 in the direction from the second base plate 21 to the extension plate 23. Figure 3 and Figure 4 See Figure 1 When the protective plate 20 is in the first position, the extension plate 23 extends beyond the fixed plate 10, so that from the second base plate 21 to the extension plate 23, the extension plate 23 also extends beyond the surface of the screen body 200, that is, beyond the side surface of the screen body 200. When the screen body 200 is subjected to external force from the side, the extension plate 23 can protect the display screen, thereby mitigating the impact of external force on the display screen, reducing the risk of display screen breakage, and especially effectively preventing damage to the LED beads on the display screen.

[0062] See also Figure 3 and Figure 4In one embodiment of this application, the hinge assembly 30 may include a first hinge plate 31, a second hinge plate 32, and a limiting rod 33. The first hinge plate 31 is hinged to the fixed plate 10 via a first pivot 311 and to the guard plate 20 via a second pivot 312. A first torsion spring 313 is sleeved on the first pivot 311, and the force-applying end of the first torsion spring 313 abuts against the fixed plate 10 and the first hinge plate 31, respectively. The second hinge plate 32 is hinged to the fixed plate 10 via a third pivot 321 and to the guard plate 20 via a fourth pivot 322. A second torsion spring is sleeved on the third pivot 321, and the force-applying end of the second torsion spring abuts against the fixed plate 10 and the second hinge plate 32, respectively. The first hinge plate 31, the fixed plate 10, and the guard plate 20 can all rotate relative to each other via the first rotating shaft 311 and the second rotating shaft 312. The second hinge plate 32, the fixed plate 10, and the guard plate 20 can all rotate relative to each other via the third rotating shaft 321 and the fourth rotating shaft 322, thereby realizing the switching of the guard plate 20 relative to the fixed plate 10 between the first position and the second position.

[0063] The limiting rod 33 is rotatably mounted on the fourth rotating shaft 322. A third torsion spring 331 is sleeved on the fourth rotating shaft 322. The force-applying end of the third torsion spring 331 abuts against the limiting rod 33 and the first hinge plate 31 respectively. When the guard plate 20 is in the first position, one end of the limiting rod 33 is engaged with the first hinge plate 31.

[0064] When the display screen is used alone, the elastic force of the first torsion spring 313 and the second torsion spring causes the first hinge plate 31 and the second hinge plate 32 to spring up, or stand upright. The first hinge plate 31 and the second hinge plate 32 support the protective plate 20 at a certain height, creating a predetermined distance between the protective plate 20 and the fixed plate 10, placing the protective plate 20 in a first position relative to the fixed plate 10. Simultaneously, one end of the limiting rod 33 engages with the first hinge plate 31, and the elastic force of the third torsion spring 331 locks the relative positions of the limiting rod 33 and the first hinge plate 31, and the limiting rod 33 and the second hinge plate 32, thereby locking the position of the protective plate 20 relative to the fixed plate 10. This ensures that the protective plate 20 remains in the first position, thus protecting the four corner areas of the screen body 200.

[0065] When two displays need to be spliced ​​together, first release the latch between the limiting rod 33 and the second hinge plate 32, that is, release the locking of the limiting rod 33. At this time, the first hinge plate 31, the fixed plate 10, and the guard plate 20 can all rotate relative to each other, and the second hinge plate 32, the fixed plate 10, and the guard plate 20 can all rotate relative to each other. The other display can drive the guard plate 20 to move, thereby allowing the guard plate 20 to move from the first position along... Figure 3The screen moves to the second position in the direction indicated by the dashed arrow, causing the guard plate 20 to abut against the fixing plate 10. At this time, the first hinge plate 31 and the second hinge plate 32 are folded, and the first torsion spring 313, the second torsion spring and the third torsion spring 331 are all compressed. The height of the guard plate 20 is reduced, so that the guard plate 20 is roughly flush with the surface of the frame, allowing the two displays to be smoothly spliced ​​and reducing the gap between the two displays after splicing.

[0066] When the two displays are separated, after the external force on the other display is removed, the first hinge plate 31 and the second hinge plate 32 automatically return to their spring-up state under the elastic action of the first torsion spring 313 and the second torsion spring, and the guard plate 20 is located in the first position relative to the fixed plate 10. At the same time, under the elastic action of the third torsion spring 331, the limiting rod 33 automatically engages with the first hinge plate 31, so that the guard plate 20 can be kept in the first position.

[0067] To limit the spring-up amplitude of the first hinge plate 31 and the second hinge plate 32, see below. Figure 3 and Figure 4 In one embodiment of this application, a limiting plate 13 is provided on the fixed plate 10 at the position corresponding to the second hinge plate 32. When the guard plate 20 is in the first position, the second hinge plate 32 abuts against the limiting plate 13. Under the elastic action of the first torsion spring 313 and the second torsion spring, the first hinge plate 31 and the second hinge plate 32 change from a folded state to a pop-up state. At this time, the second hinge plate 32 abuts against the limiting plate 13, and the limiting plate 13 restricts the second hinge plate 32 from continuing to rotate relative to the fixed plate 10, thereby limiting the rotation range of the second hinge plate 32, that is, limiting the pop-up range of the second hinge plate 32. At the same time, based on the limiting plate 13 limiting the rotation range of the second hinge plate 32, and the engagement between the upper limit rod 33 and the first limiting rod 33 on the fourth rotating shaft 322, the pop-up range of the first limiting rod 33 is also correspondingly limited, and thus the preset height of the first position of the guard plate 20 is also limited.

[0068] By setting different relative positions between the limiting plate 13 and the second hinge plate 32, different bounce amplitudes of the second hinge plate 32 and the first hinge plate 31 can be set, thereby meeting different preset height setting requirements.

[0069] See also Figure 3 and Figure 4In this embodiment, another way to limit the bounce amplitude is that the fixed plate 10 is provided with limiting grooves 14 at the positions corresponding to the first hinge plate 31 and the second hinge plate 32, respectively, to cooperate with the first hinge plate 31 and the second hinge plate 32. When the guard plate 20 is in the first position, the first hinge plate 31 and the second hinge plate 32 are respectively inserted into the corresponding limiting grooves 14. When the first hinge plate 31 and the second hinge plate 32 change from the folded state to the bounced state, the first hinge plate 31 and the second hinge plate 32 are respectively inserted into the corresponding limiting grooves 14. By using parameters such as the width and depth of the limiting grooves 14, the relative position of the first hinge plate 31 and the second hinge plate 32 with the limiting grooves 14 can be limited, thereby limiting the first hinge plate 31 and the second hinge plate 32 from continuing to rotate relative to the fixed plate 10, and limiting the rotation amplitude of the first hinge plate 31 and the second hinge plate 32, that is, limiting the bounce amplitude of the first hinge plate 31 and the second hinge plate 32.

[0070] It should be noted that, in the embodiments of this application, the above two methods of limiting the bounce amplitude can be implemented individually or in combination, and the embodiments of this application do not impose specific limitations.

[0071] See also Figure 4 In one embodiment of this application, the first hinge plate 31 and the second hinge plate 32 are implemented such that at least the first hinge plate 31 is a U-shaped plate, and the hinge is achieved through the side of the U-shaped plate. The first hinge plate 31, being a U-shaped plate, can be hinged to the first rotating shaft 311 and the second rotating shaft 312 through its side plates, and can be engaged with the limiting rod 33 through the bottom plate of the side plates. The second hinge plate 32 can be a U-shaped plate, or it can be other structures, such as having two side plates that are respectively hinged to the third rotating shaft 321.

[0072] Furthermore, one arrangement between the limiting rod 33 and the first hinge plate 31 and the second hinge plate 32 is as follows: the first hinge plate 31 has a locking groove 314 at the position corresponding to the limiting rod 33; when the second hinge plate 32 is a U-shaped plate, the second hinge plate 32 has an installation groove 323 at the position corresponding to the limiting rod 33; at least a portion of the limiting rod 33 is located within the installation groove 323, and one end of the limiting rod 33 has a latch. When the guard plate 20 is in the first position, the limiting rod 33 is latched to the bottom of the locking groove 314 through the latch. The installation groove 323 prevents the limiting rod 33 from moving angularly along the axial direction of the fourth rotating shaft 322, ensuring that the limiting rod 33 can move within the limited range of the installation groove 323, ensuring that the limiting rod 33 can accurately latch to the locking groove 314 on the first hinge plate 31, and ensuring the locking function of the limiting rod 33 is realized.

[0073] Furthermore, to make the splicing of the two displays even faster, please continue to see... Figure 3 and Figure 4 In some possible embodiments of this application, the fourth rotating shaft 322 has a centerline extending in the radial direction (the centerline is as follows: ...). Figure 4 (As shown by the dashed line in the middle) The limiting rod 33 is set on one side of the center line; the guard plate 20 is provided with through holes 24 and protrusions 25 symmetrically arranged on both sides of the center line. The through holes 24 are set at the positions corresponding to the limiting rod 33. The through holes 24 allow the protrusions 25 on another corner guard structure 100 to extend into them, so as to drive the limiting rod 33 to move and release the locking between the limiting rod 33 and the first hinge plate 31.

[0074] In this configuration, one way to set the limiting rod 33 is that one end of the limiting rod 33 is provided with a latch, and the other end of the limiting rod 33 is a driving end. When the guard plate 20 is in the first position, the limiting rod 33 is engaged with the bottom of the slot of the locking groove 314 through the latch, and the driving end of the limiting rod 33 extends into the through hole 24 or is located below the corresponding position of the through hole 24.

[0075] When two displays need to be spliced ​​together, the protrusion 25 on the corner protection structure 100 of one display extends into the through hole 24 of the corner protection structure 100 of the other display. That is, the guard plates 20 of the corner protection structures 100 of the two displays abut against each other, and the through holes 24 and protrusion 25 on the two guard plates 20 are connected to each other. Thus, the protrusion 25 drives the limiting rod 33 in the other corner protection structure 100 to move. Based on the lever principle, the protrusion 25 squeezes the driving end of the limiting rod 33, causing the limiting rod 33 to rotate around the fourth hinge. The end with the latch is raised, thereby releasing the latch between the limiting rod 33 and the first hinge plate 31.

[0076] At this time, the first hinge plate 31, the fixed plate 10, and the guard plate 20 can all rotate relative to each other, and the second hinge plate 32, the fixed plate 10, and the guard plate 20 can all rotate relative to each other. The two displays press against each other, thereby driving the guard plate 20 to move, thus enabling the guard plate 20 to move from the first position along... Figure 3 The dotted arrow in the diagram indicates that the screen 20 is moved to the second position, so that the protective plate 20 abuts against the fixing plate 10, thereby completing the splicing of the two displays and making the splicing of the two displays faster.

[0077] When the two displays are separated, after the external force on the other display is removed, the first hinge plate 31 and the second hinge plate 32 automatically return to their spring-up state under the elastic action of the first torsion spring 313 and the second torsion spring, and the guard plate 20 is located in the first position relative to the fixed plate 10. At the same time, under the elastic action of the third torsion spring 331, the limiting rod 33 automatically engages with the first hinge plate 31, so that the guard plate 20 can be kept in the first position.

[0078] Furthermore, the protective plate 20 is also provided with an extension hole 241 that communicates with the through hole 24. The diameter of the extension hole 241 is smaller than the diameter of the protrusion 25. The extension hole 241 reduces the contact area between the through hole 24 and the protrusion 25, reducing the friction between them. This allows the protrusion 25 to smoothly enter and exit the through hole 24, reducing the difficulty of splicing and disassembling the two displays.

[0079] Based on the above embodiments, this application also provides a display screen, including: a screen body 200 and a corner protection structure 100, wherein the corner protection structure 100 is the corner protection structure 100 described in the above embodiments, and the corner protection structure 100 is disposed on the screen body 200.

[0080] The display screens in this application embodiment include, but are not limited to: transparent display screens, liquid crystal display screens, OLED (Organic Light-Emitting Diode) display screens, MicroLED displays, etc. For the specific structure of the corner protection structure 100, please refer to the implementation of the corner protection structure 100 described in the above embodiments; it will not be repeated here.
