DETAILED DESCRIPTION

[0047] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0048] An embodiment of the present application provides a display panel. FIG1 shows a top view of the display panel 10. As shown in FIG1 , the display panel 10 comprises a display area 100 and a frame area 200. The display area 100 is adjacent to the frame area 200, and the portion of the display panel 10 located in the display area 100 is configured to perform a display function.

[0049] The present application provides a box frame. Referring to Figure 1 , the box frame comprises a frame body 1 and a protective device 2. The protective device 2 comprises a movable mechanism 20 and a protective member 24 connected to the movable mechanism 20. The protective member 24 is located outside the frame body 1. The movable mechanism 20 is movably mounted on the frame body 1 and drives the protective member 24, enabling the protective device 2 to switch between a protective state and a yielding state.

[0050] When the protective device 2 is in the protective state, the moving mechanism 20 drives the protective end of the protective member 24 to extend out of one side of the frame body 1. When the protective device 2 is in the yielding state, the moving mechanism 20 drives the protective end of the protective member 24 to retract.

[0051] It should be noted that, first, the outside of the frame body 1 refers to the space outside the frame body 1's frame frame. The outside corresponds to the interior space formed by the four frames of the frame body 1, which can be understood as the inside of the frame body 1. In this embodiment, the protective member 24 is entirely located outside the frame body 1, and the movable mechanism 20 partially extends from the inside of the frame body 1 and connects to the protective member 24.

[0052] Secondly, the display side of the frame body 1 refers to the side of the frame body 1 for mounting the display device. The protection end of the protection member 24 is an end portion of the protection member 24 corresponding to the edge of the display device and used to protect the display device from being damaged by collision.

[0053] Finally, the yielding state means that when two adjacent box frames are assembled and the gap between the box frames becomes smaller than a certain value, the moving mechanism 20 drives the protective member 24 to move in the direction away from the display side of the frame body 1, and the protective member 24 is gradually retracted, thereby meeting the installation requirements of the display side between the box frames, and in the assembly process, achieving a good anti-collision effect on the edge of the display screen installed on the display side.

[0054] The protective state means that when the gap between two adjacent cabinet frames increases to a certain value during disassembly, the moving mechanism 20 drives the protective member 24 to move toward the display side of the frame body 1. The protective member 24 gradually extends to protect the display device at the edge of the display screen installed on the display side of the frame body 1, thereby preventing damage during packaging and transportation.

[0055] The protective device 2 in this application can automatically switch between a yielding state and a protective state depending on whether the housing frame is in use or not. This provides real-time, full-process, and comprehensive protection for the display screen mounted on the display side of the frame body 1. This reduces and prevents bumps and damage to the display screen during various processes such as packaging, transportation, and installation.

[0056] In some embodiments, referring to FIG2 , the moving mechanism 20 includes a fixed assembly 21, an elastic assembly 22, and a transmission assembly 23. The fixed assembly 21 is connected to the frame body 1, and the transmission assembly 23 is connected to the fixed assembly 21 via the elastic assembly 22. The transmission assembly 23 is connected to the protective member 24. The elastic assembly 22 is displaced within the fixed assembly 21, causing the transmission assembly 23 to drive the protective member 24 to also displace.

[0057] When the elastic component 22 is squeezed by external force, the transmission component 23 drives the protective end of the protective piece 24 to retract into the frame body 1. When the external force applied to the elastic component 22 disappears, the elastic component 22 generates a rebound force, so that the transmission component 23 drives the protective end of the protective piece 24 to extend out of the frame body 1.

[0058] In this embodiment, the external force applied to the elastic component 22 is the squeezing force generated between the box frames during the installation of the box frames.

[0059] Specifically, during the assembly process, referring to Figures 7a to 7d, as the gap between the two box frames becomes smaller and smaller, the squeezing force on the elastic component 22 gradually increases, so that the elastic component 22 drives the protective part 24 through the transmission mechanism to gradually move away from the display side of the frame body 1 until the box frame assembly is completed.

[0060] During this process, the protective device 2 transitions from its protective state to its yielding state, relying on the squeezing force. As the protective member 24 gradually retracts, it not only meets the installation requirements between the display sides of the frame body 1 and prevents gaps between the frame bodies 1, but also ensures the real-time and full-process operation of the protective device 2. That is, until the cabinet frame is assembled, the protective member 24 remains positioned at the display-side edge of the frame body 1, protecting the display device and preventing damage to the display device during installation.

[0061] Specifically, during the disassembly process, as the gap between the two boxes becomes larger and larger, the squeezing force on the elastic component 22 gradually decreases until it disappears.

[0062] During this process, the resilient force of the elastic component 22 completes the transition from the yielding state to the protective state. As the protective member 24 gradually extends, the protective end of the protective member 24 continues to protect the display device mounted on the display side of the frame body 1, thus preventing damage to the display screen caused by other process steps.

[0063] The present application realizes the automatic protection function of the protection device 2 and the real-time, full-range and all-round protection through the cooperation between the fixing component 21, the elastic component 22 and the transmission component 23.

[0064] In some embodiments, referring to FIG. 2 and FIG. 3 , the elastic assembly 22 includes a sliding member 220 and an elastic member 221 . The elastic member 221 is sleeved on the sliding member 220 to provide power for the displacement of the sliding member 220 .

[0065] When the two box frames are installed, an extrusion force is applied to the sliding member 220, causing the sliding member 220 to drive the transmission assembly 23 and the protective member 24 to move in a direction away from the display side of the frame body 1. During the displacement process, the elastic member 221 mounted on the sliding member 220 is also compressed to meet the installation requirements of the box frame.

[0066] When the two box frames are disassembled, the squeezing force applied to the sliding member 220 disappears. At this time, the rebound force of the elastic member 221 is applied to the sliding member 220, causing the sliding member 220 to drive the transmission assembly 23 and the protective member 24 to move toward the display side of the frame body 1 to meet the protection requirements.

[0067] The sliding member 220 and the elastic member 221 cooperate with each other to realize the automatic switching of the protective device 2 from the protective state to the yielding state. The structure is simple and the operation is convenient.

[0068] Furthermore, the elastic member 221 is a compression spring that can absorb the impact or vibration generated when the box frame is installed, thereby reducing damage to the display device caused by the installation.

[0069] In some embodiments, referring to Figures 2 and 3 , the fixing assembly 21 includes a base 210. A first stopper 211 is provided on a side of the base 210 away from the transmission assembly 23. A second stopper 2201 is provided on the slider 220. When the slider 220 extends into the base 210, the second stopper 2201 cooperates with the first stopper 211 to limit the displacement of the slider 220 in the base 210.

[0070] 3 , in this embodiment, the provision of the first limiting portion 211 and the second limiting portion 2201 can prevent the protective device 2 from being displaced significantly during the switching process from the yielding state to the protective state, and when the resilience of the elastic member 221 drives the sliding member 220 to move, thereby preventing the sliding member 220 from vibrating with the bottom wall of the base 210 or extending out of the inner wall of the base 210 and then extending out of the display side of the frame body 1, thereby causing damage to the display device.

[0071] In some embodiments, the first limiting portion 211 and the second limiting portion 2201 may be engaged with each other by abutting, snapping, or plugging.

[0072] In some embodiments, when the first limiting portion 211 is configured as a protrusion, the second limiting portion 2201 is configured as a groove matching the protrusion, or when the second limiting portion is configured as a protrusion, the first limiting portion 211 is configured as a groove matching the protrusion.

[0073] Specifically, the protrusions can be positioned as positioning pins, and the recesses can be positioned as positioning pin holes.

[0074] In some embodiments, the first limiting portion 211 is configured as a limiting plate with a through hole, and the second limiting portion 2201 is configured as a limiting ring, which is sleeved on the sliding member 220, and the diameter of the limiting ring is larger than the diameter of the through hole.

[0075] 3 , the purpose of the through hole in the protective plate is to allow the force-bearing end of the slider 220 to pass through so that an external force can be applied to the slider 220 during the assembly of the box frame to cause the slider 220 to move. It should be noted that the force-bearing end of the slider 220 is the end that withstands the extrusion force generated during the installation of the box frame.

[0076] When the protection device 2 is in the protection state, the limiting plate and the limiting ring are in contact with each other to achieve a limiting effect on the sliding member 220 .

[0077] Preferably, the limiting plate is detachably connected to the base 210 so that the fixing assembly 21 can replace the limiting plate according to the size of the limiting ring to meet the needs of different scenarios.

[0078] In some embodiments, the through-hole shape is selected from one of a circle, a square, an ellipse, a hexagon and an irregular shape.

[0079] The shape of the through hole can be selected according to the shape of the end of the sliding member 220 close to the display side of the frame body 1. Preferably, the shape of the through hole on the limiting plate is a square hole.

[0080] In some embodiments, referring to FIG. 3 and FIG. 5 , a stepped circular hole 213 is defined in the base 210 , and the sliding member 220 and the compression spring are located in the stepped circular hole 213 to position the sliding member 220 and the elastic member 221 .

[0081] Specifically, the stepped circular hole 213 is provided with a plurality of holes having different diameters in a direction close to the frame body 1 .

[0082] In this embodiment, with continued reference to FIG3 , the stepped circular hole 213 has three holes with different diameters as it approaches the display side of the frame body 1, and the diameters increase sequentially. For ease of understanding, the stepped circular holes 213 can be defined as a first stepped hole, a second stepped hole, and a third stepped hole as they approach the display side of the frame body 1.

[0083] The diameter of the first stepped hole is smaller than the diameter of the compression spring and is equal to or larger than the diameter of the connecting end of the sliding member 220. It should be noted that the connecting end of the sliding member 220 is an end connected to the transmission assembly 23.

[0084] The diameter of the second stepped hole is smaller than the diameter of the limiting ring and is equal to or larger than the diameter of the compression spring.

[0085] The diameter of the third stepped hole is smaller than the height of the limiting plate and is equal to or larger than the diameter of the limiting ring.

[0086] 3 and 7a-d, when the protective device 2 is in the protective state, the force-bearing end of the sliding member 220 extends through the through hole, the limiting ring of the sliding member 220 fits with the limiting plate of the base, and the compression spring is in the original state.

[0087] At this time, the internal state of the stepped circular hole 213 is: the first stepped hole contains the connecting end of the sliding part 220, the second stepped hole contains the sliding part 220 and a partial compression spring, and the third stepped hole contains the sliding part 220, a partial compression spring and a limit ring.

[0088] Then, a compressive force is applied to the force-bearing end of the slider 220, causing the slider 220 to move away from the display side of the frame body 1, thereby driving the transmission assembly 23 connected thereto to move, and in turn driving the protective member 24 to move away from the display side of the frame body 1, completing the transition of the protective device 2 from the protective state to the yielding state. It should be noted that the displacement range of the slider 220 within the base 210 is equivalent to the aperture of the third stepped hole.

[0089] At this time, the state inside the stepped circular hole 213 is as follows: the connecting end of the sliding member 220 extends out of the first stepped hole, the compression spring is completely compressed into the second stepped hole, and the limiting ring abuts against the diameter-changing surfaces of the second and third stepped holes.

[0090] The present application provides a stepped circular hole 213 on the side of the base 210 away from the display side of the frame body 1. The stepped circular hole 213 uses different hole diameters to limit the displacement of the sliding member 220 and the compression spring in the base 210, thereby realizing the automatic switching of the protective device 2 between the protective state and the yielding state.

[0091] In some embodiments, referring to Figures 4 and 5, the sliding member 220 further includes a third limiting portion 2202, and a first matching portion 2130 is provided on the stepped circular hole 213. The third limiting portion 2202 cooperates with the first matching portion 2130 to limit the rotation of the sliding member 220 in the base 210.

[0092] Specifically, the third limiting portion 2202 is provided on the second limiting portion 2201, and the first matching portion 2130 is provided on the third stepped hole. When the protective device 2 is in the protective state, the first limiting portion 211 abuts the second limiting portion 2201, while the third limiting portion 2202 and the first matching portion 2130 also match. This not only limits the displacement of the sliding member 220 in the axial direction (i.e., the direction away from or toward the display side of the frame body 1), but also limits the rotation of the sliding member 220 in the axial direction through the cooperation between the third limiting portion 2202 and the first matching portion 2130 without hindering the displacement of the sliding member 220. This ensures the stability of the elastic component 22, and thus the stability of the protective device 2.

[0093] Furthermore, the matching manner between the third limiting portion 2202 and the first matching portion 2130 includes but is not limited to plugging and snapping.

[0094] In some embodiments, the third limiting portion 2202 is configured as a boss, and the first matching portion 2130 is configured as a groove. When the sliding member 220 extends into the base 210, the boss is wedged into the groove.

[0095] When the protection device 2 is in the protection state, the engagement between the boss and the groove can effectively prevent the sliding member 220 from rotating. At the same time, when switching to the yielding state, the boss and the groove are also separated as the sliding member 220 is displaced.

[0096] In some embodiments, the second limiting portion 2201 and the third limiting portion 2202 are an integrated structure.

[0097] Providing an integrated structure facilitates production and reduces the installation process with the sliding member 220 .

[0098] 4 , the second limiting portion 2201 is a limiting ring, and the third limiting portion 2202 is a protrusion on the limiting ring. Both are manufactured using the same mold.

[0099] Specifically, when the limiting ring abuts against the limiting plate, the protrusion on the limiting ring also engages with the groove provided on the third stepped hole, thereby simultaneously limiting the axial displacement and rotation of the sliding member 220 .

[0100] In some embodiments, referring to Figures 2 to 6 , the transmission assembly includes a transmission block 230, a guide member disposed on a side of the transmission block 230 proximate to the base 210, and a second mating portion disposed on a side of the base 210 proximate to the transmission block 230. Alternatively, the second mating portion is disposed on a side of the transmission block 230 proximate to the base 210, and the guide member is disposed on a side of the base 210 proximate to the transmission block 230. When the transmission block 230 is displaced relative to the base 210, the guide member and the second mating portion engage.

[0101] Furthermore, the guide member can be configured as a guide pin 231, and the second matching portion can be configured as a guide pin hole 214. Preferably, the number of the guide pins 231 and the guide pin holes 214 matched therewith are both set to four.

[0102] In one embodiment, the guide pin hole 214 is provided on a side surface of the base 210 away from the display side of the frame body 1. The guide pin 231 is provided on a side surface of the transmission block 230 close to the base 210.

[0103] 3 , 5 and 6 , when the protective device 2 switches from the protective state to the yielding state, as the transmission block 230 moves away from the display side of the frame body 1 , the guide pin 231 on the transmission block 230 gradually moves out of the guide pin hole 214 on the base 210 .

[0104] When the protective device 2 switches from the yielding state to the protecting state, as the transmission block 230 moves toward the display side of the frame body 1 , the guide pin 231 on the transmission block 230 is gradually connected with the guide pin hole 214 on the base 210 .

[0105] In the present application, a guide member and a second matching portion are provided to precisely guide the displacement of the transmission block 230 relative to the base 210, thereby ensuring the stability of the protective device 2 during the switching process between the protective state and the yield state.

[0106] In some embodiments, the transmission assembly 23 and the elastic assembly 22 are detachably connected. Preferably, the transmission assembly 23 and the elastic assembly 22 are connected by a threaded connection.

[0107] Specifically, a threaded hole is provided at the connecting end of the sliding member 220 , a first connecting hole is provided on the transmission block 230 , and the connecting bolt 233 passes through the first connecting hole and is threadedly connected to the threaded hole of the sliding member 220 .

[0108] When the protective device 2 switches between the protective device 2 and the yielding state, the sliding member 220 is displaced in the base 210, and the corresponding driving transmission block 230 is displaced in the direction of approaching and away from the display side of the frame body 1, thereby driving the protective member 24 to be displaced, so as to protect the display device on the display side of the frame body 1 or meet the installation requirements.

[0109] In some embodiments, when the box frame is being packaged or transported, a fastening portion is provided between the transmission assembly 23 and the fixing assembly 21 to limit the displacement of the transmission assembly 23 relative to the fixing assembly 21 .

[0110] Specifically, referring to Figures 2, 5, and 6, the fastening portion includes a rectangular groove 215 formed on the top surface of the base 210, a rectangular block 232 disposed on the transmission block 230, and a fastening bolt 212. When the transmission block 230 and the base 210 are close together, the rectangular block 232 fits into the rectangular groove 215, and the fastening bolt 212 passes through the rectangular block 232 and is threadedly connected to the base 210, thereby achieving a secure connection between the transmission block 230 and the base 210.

[0111] When assembling the two box frames, the fastening bolts 212 need to be loosened so that the transmission block 230 can be displaced relative to the base 210 to complete the protective device 2 yielding state.

[0112] When the two box frames are disassembled and transported separately, the fastening bolts 212 need to be tightened so that the transmission block 230 is tightly connected to the base 210 to facilitate subsequent packaging and transportation.

[0113] Furthermore, the top of the fastening bolt 212 is a butterfly-shaped structure.

[0114] The butterfly structure setting can increase the contact area between the user and the bolt, which helps the user to loosen or tighten the bolt and save physical effort.

[0115] The present application enhances the stability between the transmission assembly 23 and the fixing assembly 21 by providing a fastening portion, thereby preventing the transmission assembly 23 from being displaced relative to the fixing assembly 21 during transportation, thereby ensuring that the display module 4 is not damaged by collision during transportation.

[0116] In some embodiments, the box frame further includes a trigger device, and the trigger device and the protective device 2 are respectively located on opposite sides of the frame body 1 .

[0117] 7a-d, when two box frames are assembled, the trigger device of one box frame cooperates with the protective device 2 of the other box frame to switch the protective state of the protective device 2 to the yield state, and the two box frames fit together.

[0118] When the two box frames are disassembled, the trigger device of one box frame cooperates with the protection device 2 of the other box frame to switch the yielding state of the protection device 2 to the protection state, and the two box frames are separated.

[0119] For ease of understanding and description, the two box frames used for assembly are named as a first box frame and a second box frame.

[0120] When assembling the first box frame and the second box frame, first, the user can align the frame where the protective device 2 of the first box frame is located with the frame where the trigger device of the second box frame is located, and then slowly place the first box frame on the second box frame. At this time, the first box frame generates an extrusion force on the second box frame to act on the trigger device. The trigger device and the protective device 2 cooperate, and the extrusion force acts on the protective device 2 through the trigger device to change the state of the protective device 2.

[0121] In this application, the extrusion force generated during the installation of the two box frames acts on the protective device 2 through the trigger device, applying a certain external force to the protective device 2, and then cooperating with the internal structure of the protective device 2 (that is, the contents of the fixing component 21, the elastic component 22 and the transmission component 23, refer to the above embodiment, and will not be repeated here), so that the protective device 2 can automatically switch between the protective state and the yield state, so as to realize the automaticity, real-timeness and full process of the protective device 2.

[0122] In some embodiments, the trigger device has an escape zone located at the orthographic projection of the base 210, the frame body 1, and the protective member 24 on the same housing frame. When two housing frames are assembled, the escape zone of one housing frame can accommodate the trigger device of the other housing frame, allowing the protective device 2 to switch between the protective state and the yield state.

[0123] Specifically, the trigger device is configured as a trigger pin 3, and an avoidance hole is opened in the avoidance area.

[0124] 7a to 7d , when the first box frame and the second box frame are assembled, as the gap between the first box frame and the second box frame becomes smaller and smaller, the trigger pin 3 provided on the second box frame also passes through the avoidance hole on the protective member 24, the frame body 1 and the base 210 in sequence, and then squeezes the sliding member 220, so that the sliding member 220 moves in a direction away from the display side of the frame body 1;

[0125] When the assembly is completed, the trigger pin 3 is fully extended into the base 210 through the avoidance hole, the force-bearing end of the sliding member 220 is completely placed in the stepped circular hole 213, and the limit ring is in contact with the diameter-changing surface in the stepped circular hole 213, and the transmission block 230 also drives the protective member 24 to retract, so that the gap between the first box frame and the second box frame is zero, thereby meeting the installation requirements of the box frame.

[0126] In some embodiments, the end of the trigger pin 3 that is connected to the sliding member 220 is designed with a smooth chamfer, and the force-bearing end of the sliding member 220 is a bevel structure.

[0127] The chamfer of the trigger pin 3 cooperates with the inclined surface structure of the sliding member 220 to quickly push the sliding member 220 to move, thereby improving the installation efficiency of the box frame.

[0128] The present application also provides a display screen box, which is applied with the box frame of any of the above embodiments and further includes a display module 4. The display module 4 is fixed to a side of the box frame where the protective end of the protective member 24 is located.

[0129] 7a to 7d, the display module 4 is mounted on the display side of the frame body 1. The portion of the protective member 24 extending out of the frame body 1 is used to protect the display module 4 located on the side of the frame body 1 from being damaged by collision.

[0130] In some embodiments, the protective member 24 is configured as a rigid flat plate structure. The size of the flat plate structure determines the range of the display module 4 it protects. Preferably, the length of the protective member 24 is the same as the length of the frame body 1 it protects.

[0131] In some embodiments, two corresponding sets of protection devices 2 and trigger devices are provided in the display screen housing to improve the stability of the display screen housing assembly.

[0132] The present application also provides a display screen, which is equipped with a display screen box according to any of the above embodiments.
