Description

Technical Field

[0001] This utility model relates to the field of display screen technology, and in particular to a display unit and a display screen. Background Technology

[0002] With the development of LED display modules, various LED display modules have gradually emerged to suit different application scenarios, such as dome displays, mobile screens, and large-size screens. Among them, dome displays refer to LED display module systems installed on the top or dome of a building, facing the audience below.

[0003] Currently, the industry typically uses two methods to prevent LED display modules from falling off. One method is using steel cables, with one end fixed to the external steel structure or enclosure, and the other end connected to or hung on the LED display module. However, display modules usually consist of multiple LED modules, requiring multiple steel cables, which not only increases costs but also creates a messy and unsightly wiring harness. The second method is using screws, which pass through the steel structure or enclosure to secure the LED display module. However, this method is complex to install and remove, and not conducive to quick maintenance of the module. Utility Model Content

[0004] One objective of this invention is to solve the technical problems of existing methods for preventing LED display modules from falling, which are either costly or complex to operate, and to provide a display unit that can stably fix the lamp board while being simple to operate and also meeting the requirement of low cost.

[0005] Another objective of this invention is to provide a display screen including the aforementioned display unit.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A display unit, comprising: The display module includes a light panel, a bottom shell, and a back cover. The light panel and the back cover are respectively located on opposite sides of the bottom shell. A signal transmission module is also provided on the side of the light panel near the back cover. The signal transmission module includes an interface. A connection hole is provided on the back cover, and the interface corresponds to the connection hole. The data connection cable includes a cable body, a main body, a connector, and a snap-fit ​​structure. The connector and the cable body are respectively disposed on different sides of the main body. The connector can pass through the connection hole to be adapted to be inserted into the interface, thereby forming an electrical connection between the data connection cable and the display module. The snap-fit ​​structure is disposed on the main body and can pass through the connection hole to be snapped and fixed to the back cover.

[0007] In some embodiments of this application, the display module includes a buffer buckle, the buffer buckle and the connecting hole are arranged on the same side of the back cover, the buffer buckle and the connecting hole are spaced apart, the buffer buckle is open at both ends and hollow inside to form a receiving space for the wire to pass through.

[0008] In some embodiments of this application, the buffer latch includes: The arc-shaped portion has one end connected to the back cover and the other end having a gap between it and the surface of the back cover, thus allowing the wire to be accommodated in the receiving space through the gap; A raised ridge is provided on the inner sidewall of the arc-shaped portion near the rear cover.

[0009] In some embodiments of this application, the snap-fit ​​structure includes: An elastic portion is disposed on the body and extends beyond the surface of the body. A pressing part is provided on the end of the elastic part that extends beyond the main body; The elastic part is elastic, and when an external force is applied to the pressing part, the elastic part can undergo elastic deformation, so that the pressing part can be relatively close to the main body and can be inserted into the display module through the connecting hole; when the external force is released, the elastic part returns to its original deformation, so that the pressing part is relatively far away from the main body and can abut against the inner wall of the back cover, so that the buckle structure is snapped and fixed on the back cover.

[0010] In some embodiments of this application, the connector is a reversible pluggable connector, and the interface in the signal transmission module is a reversible pluggable interface adapted to the connector.

[0011] In some embodiments of this application, at least one side of the edge of the connecting hole has a convex shape adapted to the buckle structure.

[0012] In some embodiments of this application, the main body includes a main body portion and a bent portion, the line is connected to the main body portion, the connector is disposed on the end of the bent portion away from the main body portion, and the main body portion and the bent portion are disposed at an angle.

[0013] In some embodiments of this application, the bottom shell is provided with mounting holes, and the rear cover is provided with assembly holes at positions corresponding to the mounting holes; the display unit further includes fasteners, which pass through the corresponding assembly holes and mounting holes, so that the rear cover is fixed to the bottom shell.

[0014] In some embodiments of this application, the bottom shell is provided with a plurality of mounting positions at intervals along the outer periphery of the rear cover; the display unit includes a plurality of magnetic components for fixed connection with an external structure, and the plurality of magnetic components are respectively disposed in the plurality of mounting positions.

[0015] A display screen includes a power signal processing module and at least one display unit as described above, wherein the display module in the display unit is fixed to an external structure, and the display module is electrically connected to the power signal processing module via the data connection line.

[0016] As can be seen from the above technical solution, this utility model has at least the following advantages and positive effects: The display unit of this utility model includes a display module and a data connection cable. The connector in the data connection cable can be plugged into the signal transmission module in the display module to form an electrical connection for signal transmission. Furthermore, by setting a snap-fit ​​structure on the data connection cable, which passes through a connection hole and snaps itself onto the back cover, the connection between the data connection cable and the display module is made more secure. It should be noted that the data connection cable is an essential component of the display unit, and the cable itself has a certain strength. Therefore, the display unit of this application effectively utilizes the data connection cable, enabling it to have both signal transmission and protective capabilities, thus eliminating the need for additional steel wire rope reinforcement. This saves on the selection, laying, and tightening of steel wire rope, thereby reducing costs and construction complexity. In addition, it effectively avoids the cumbersome installation process of screws, saving manpower and time required for installation and improving installation efficiency.

[0028] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0029] In the description of this application, it should be understood that, in the embodiments shown in the accompanying drawings, the indications of direction or positional relationships (such as up, down, left, right, front, and back, etc.) are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] Please see Figure 1 and Figure 2 This utility model provides a display unit 100, including a display module 1 and a data connection cable 2. One end of the data connection cable 2 is plugged into the display module 1 to form an electrical connection, and the other end of the data connection cable 2 can be connected to an external power signal module, so that the power signal module and the display module 1 can realize signal transmission and power transmission through the data connection cable 2.

[0032] Please see Figure 3 The display module 1 includes a lamp panel 11, a bottom shell 12, and a rear cover 13. The lamp panel 11 and the rear cover 13 are respectively located on opposite sides of the bottom shell 12. A signal transmission module 14 is provided on the side of the lamp panel 11 closest to the rear cover 13. The signal transmission module 14 includes an interface 141 adapted to a data connection cable 2. A connection hole 15 is provided on the rear cover 13, and the connection hole 15 corresponds to the interface 141 on the signal transmission module 14, so that the data connection cable 2 can pass through the connection hole 15 and be inserted into the interface 141 on the signal transmission module 14.

[0033] In some embodiments, the signal transmission module 14 can be integrated into the internal circuitry of the lamp board 11, or electrically connected to the lamp board 11 via surface mount technology. Specifically, when integrated, the circuit structure of the signal transmission module 14 can be integrally formed with the basic circuit layer of the lamp board 11, and signal interaction with other electronic components on the lamp board 11 can be achieved through internal wiring. When surface mount technology is used, the signal transmission module 14 can be soldered to a preset pad area of ​​the lamp board 11 using surface mount technology (SMT) to form a stable mechanical fixation and electrical connection relationship, thereby realizing the transmission function of electrical energy and control signals.

[0034] In some embodiments, the bottom shell 12 includes an outer frame 121 and a plurality of crossbeams 122 and vertical beams 123 connected inside the outer frame 121. The plurality of crossbeams 122 and the plurality of vertical beams 123 are cross-connected, and the connected crossbeams 122 and vertical beams 123 form a clearance opening 124.

[0035] For example, the outer frame 121 can be a rectangular frame. Vertical beams 123 are connected to the inner sidewalls at both ends of the outer frame 121 in the width direction, and horizontal beams 122 are connected to the inner sidewalls at both ends of the outer frame 121 in the length direction. The vertical beams 123 and horizontal beams 122 can be connected perpendicularly. Multiple horizontal beams 122 and multiple vertical beams 123 are intersected to form multiple square clearance openings 124 inside the outer frame 121.

[0036] The interface 141 in the signal transmission module 14 is arranged in one of the clearance openings 124 so that the data connection cable 2 can pass through the connection hole 15 on the back cover 13 and connect to the interface 141.

[0037] See Figure 3 The bottom shell 12 is provided with a mounting position 125, and the rear cover 13 is detachably connected to the mounting position 125 of the bottom shell 12. Specifically, in this embodiment, the mounting position 125 is inside the outer frame 121, that is, the surface of the outer frame 121 facing away from the lamp panel 11 is exposed to the outside.

[0038] In some embodiments, the rear cover 13 can be snapped onto the bottom shell 12. See this embodiment for details. Figure 4 and Figure 5 The rear cover 13 includes a cover body 131, an extension 132, and a bent portion 133. The extension 132 protrudes from the cover body 131 on the side near the bottom shell 12 and extends toward the light panel 11. The bent portion 133 is located at the end of the extension 132 away from the cover body 131 and is angled with the extension 132 so that the bent portion 133 and the extension 132 combine to form an approximate hook structure.

[0039] The bottom shell 12 is provided with a snap-fit ​​position 126 adapted to the hook structure, so that the hook structure can be snapped into the snap-fit ​​position 126 to realize the connection between the back cover 13 and the bottom shell 12. The snap-fit ​​position 126 can be a groove structure recessed into the surface of the bottom shell 12, or in other embodiments, the snap-fit ​​position 126 can be a hole structure provided on the bottom shell 12.

[0040] Along the width of the cover 131, two symmetrical hook structures may be provided on the cover 131. That is, the bent portion 133 of one hook structure is located on the side of the extension 132 opposite to the other hook structure. The two symmetrical hook structures work together to ensure a stable connection between the bottom shell 12 and the rear cover 13 in the display module 1. Especially when the display module 1 is horizontally installed on the top as a canopy, the bent portions 133 of the two symmetrical hook structures are tightly connected to the side wall of the fastener 126 on the bottom shell 12 due to the gravity of the bottom shell 12 and the light panel 11, thus preventing the bottom shell 12 and the rear cover 13 in the display module 1 from separating.

[0041] Along the length of the cover 131, multiple hook structures may be provided at intervals on the cover 131 to further enhance the connection reliability between the rear cover 13 and the bottom shell 12, and at the same time help to disperse stress.

[0042] See Figure 1 and Figure 3 In some embodiments, the display unit 100 may include a fastener 16. The bottom housing 12 has mounting holes 127, and the rear cover 13 has mounting holes 134 corresponding to the mounting holes 127. The fastener 16 passes through the corresponding mounting holes 134 and mounting holes 127, thus fixing the rear cover 13 to the bottom housing 12. The fastener 16 can be a bolt, screw, etc. The fastener 16 further enhances the connection stability between the rear cover 13 and the bottom housing 12.

[0043] In some embodiments, the display unit 100 includes a magnetic member 3, which is used to achieve a magnetic connection between the display module 1 and the external structure, so as to fix the display module 1 to the external structure. Specifically, multiple magnetic members 3 are provided. The bottom shell 12 is provided with multiple mounting positions 128 at intervals along the outer periphery of the rear cover 13. The multiple magnetic members 3 are respectively disposed in the multiple mounting positions 128, and the end face of the magnetic member 3 is exposed on the surface of the rear cover 13.

[0044] In some embodiments, the mounting position 128 can be an internal threaded hole, and the magnetic suction member 3 is provided with an external thread that matches the internal threaded hole, so that the magnetic suction member 3 can be screwed onto the rear cover 13.

[0045] See Figure 2 and Figure 6 The data cable 2 includes a cable body 21 and a connector 22. The connector 22 is connected to the end of the cable body 21. The connector 22 can be a Type-A connector, Type-B connector, Type-C connector, HDMI connector, DisplayPort connector, etc., and can be set according to actual needs, without limitation here.

[0046] Preferably, connector 22 is a reversible plug-in connector. Correspondingly, interface 141 in the signal transmission module 14 is a reversible plug-in interface that adapts to the connector, so that the operator does not need to pay attention to the orientation of connector 22 and can quickly connect the data connection cable 2 to the display module 1. Specifically, connector 22 is a Type-C connector, and interface 141 is a Type-C interface.

[0047] See Figure 7 and Figure 8 The data cable 2 includes a body 23, and a connector 22 connects to the cable 21 via the body 23. The connector 22 protrudes from one side of the body 23. An operator can insert and remove the data cable 2 by manipulating the body 23 to connect or disconnect the connector 22 from the interface 141.

[0048] In some embodiments, the data cable 2 includes an anti-slip portion 24 disposed on the side wall of the main body 23 to increase friction and prevent slippage when the operator plugs or unplugs the data cable 2. Exemplarily, the anti-slip portion 24 may include multiple spaced-apart ribs. In other embodiments, the anti-slip portion 24 may also be configured in other forms, such as a groove recessed into the surface of the main body 23; or, other protrusions may be provided on the surface of the main body 23, including patterns of any shape or style.

[0049] See Figure 6 In some embodiments, the main body 23 includes a main body portion 231 and a bent portion 232. A wire 21 is connected to the main body portion 231, and a connector 22 is disposed on the end of the bent portion 232 away from the main body portion 231. The main body portion 231 and the bent portion 232 are arranged at an angle. For example, the angle between the main body portion 231 and the bent portion 232 is 90 degrees.

[0050] Alternatively, in some embodiments of this application, the bending portion 232 in the main body 23 of the data connection line 2 can be omitted, such as... Figure 6 The main body 23 is located on the right side. The connector 22 and the wire 21 can be respectively provided on different sides of the main body 231. For example, the connector 22 and the wire 21 can be respectively provided on two opposite sides of the main body 231. Alternatively, in another embodiment, the connector 22 and the wire 21 can be respectively provided on adjacent sides of the main body 231. The specific arrangement can be determined according to actual needs and is not limited here.

[0051] The data cable 2 can have a main body 23 and a connector 22 at both ends of the cable body 21. For example... Figure 6 As shown, the main bodies 23 at both ends of the cable 21 can be configured with different structural forms. In other embodiments, in a data connection cable 2, the main bodies 23 at both ends of the cable 21 can also be configured with the same structural form.

[0052] Furthermore, it is understood that the connectors 22 provided on different bodies 23 can be configured as the same type of connector 22, for example, both ends can be configured as Type-C connectors 22; or, the connectors 22 provided on different bodies 23 can also be configured as different types of connectors 22, for example, one connector 22 is a Type-C connector 22 and the other connector 22 is a Type-A connector 22.

[0053] Please see Figures 6 to 8 The data connection cable 2 includes a snap-fit ​​structure 25. The snap-fit ​​structure 25 is disposed on the main body 23. While the connector 22 is inserted into the interface 141 of the signal transmission module 14, the snap-fit ​​structure 25 can pass through the connection hole 15 on the rear cover 13 of the display module 1 and snap-fit ​​and fix it to the rear cover 13, so as to enhance the connection stability and reliability between the data connection cable 2 and the display module 1, and effectively prevent the connection between the data connection cable 2 and the display module 1 from becoming loose and affecting the signal transmission.

[0054] Specifically, see Figure 6 The snap-fit ​​structure 25 includes an elastic portion 251 and a pressing portion 252. The elastic portion 251 is disposed on the main body 23 and extends beyond the surface of the main body 23. The pressing portion 252 is disposed on the end of the elastic portion 251 that extends beyond the main body 23. The elastic portion 251 is elastic; when an external force is applied to the pressing portion 252, the elastic portion 251 can undergo elastic deformation, allowing the pressing portion 252 to approach the main body 23 and extend into the interior of the display module 1 through the connecting hole 15. After the elastic portion 251 recovers its deformation, the pressing portion 252 moves away from the main body 23 and abuts against the inner wall of the back cover 13, thus snapping the snap-fit ​​structure 25 onto the back cover 13.

[0055] In some embodiments, the elastic portion 251 includes a straight section 2511 and an arc-shaped section 2512. One end of the straight section 2511 is disposed on the main body 23. Exemplarily, the straight section 2511 includes an arc-shaped transition surface 2511a. The transition surface 2511a is located on the back side of the junction between the straight section 2511 and the rear cover 13, which can evenly distribute stress, preventing stress concentration and cracking, thereby improving the connection stability and durability between the straight section 2511 and the main body 23. Furthermore, the transition surface 2511a makes the end of the straight section 2511 approximately arched, providing better bending resistance, thus enhancing the structural strength of the straight section 2511 and reducing the possibility of deformation or vibration.

[0056] The straight section 2511 extends in the same direction as the main body 23 toward the connector 22, and extends beyond the surface of the main body 23. An arc-shaped section 2512 is provided at the end of the straight section 2511 that extends beyond the surface of the main body 23. The arc-shaped section 2512 has an approximately C-shaped cross-section, with its two ends on the same side due to a fold in the middle. The arc-shaped section 2512 is connected to the pressing part 252, and the pressing part 252 is located on the side of the straight section 2511 opposite to the connector 22.

[0057] Furthermore, the pressing part 252 is set at an angle to the straight section 2511. The curved section 2512 is elastic; therefore, when an external force is applied to the pressing part 252, causing it to move towards the straight section 2511, the curved section 2512 deforms. After the applied external force is released, the curved section 2512 springs back to its original position, and the pressing part 252 follows the curved section 2512 to return to its original position.

[0058] In some embodiments, the pressing part 252 includes a body 2521 and an extension 2522. One side of the body 2521 is connected to the arcuate segment 2512, and the other side is connected to the extension 2522. The width of the body 2521 can be the same as the width of the arcuate segment 2512 to ensure a stable connection between the body 2521 and the arcuate segment 2512. The width of the extension 2522 is smaller than the width of the body 2521.

[0059] See Figure 9 and Figure 10 The connecting hole 15 on the back cover 13 has at least one side profile that is a convex shape adapted to the snap-fit ​​structure 25, so that the snap-fit ​​structure 25 is snapped and fixed on the back cover 13.

[0060] In some embodiments, the back cover 13 includes a first limiting portion 135, which is disposed on the side of the cover 131 near the lamp panel 11. The edge contour of the first limiting portion 135 is U-shaped. The first limiting portion 135 is provided corresponding to the connecting hole 15, such that the connecting hole 15 includes a first connecting hole 151 with an edge contour of U-shape. The snap-fit ​​structure 25 can be snapped and fixed to the first limiting portion 135 through the first connecting hole 151.

[0061] Specifically, see Figure 8 and Figure 10The first limiting part 135 includes a limiting wall 1351, a top wall 1352, and a lower end wall 1353. During the process of inserting the connector 22 in the data connection cable 2 into the interface 141, the lower end wall 1353 of the first limiting part 135 presses against the opposite sides of the body 2521, causing the entire pressing part 252 and the arc segment 2512 to deform; until the body 2521 is completely inside the display module 1 and disengages from the lower end wall 1353 of the first limiting part 135; then, under the elastic action of the arc segment 2512, the arc segment 2512 and the pressing part 252 rebound, so that the end face of the body 2521 in the pressing part 252 away from the arc segment 2512 abuts against the limiting wall 1351, and the extension segment 2522 in the pressing part 252 can abut against the top wall 1352. Because the end face of the main body 2521 abuts against the limiting wall 1351, a stable connection between the pressing part 252 and the back cover 13 is achieved after the external force is lost.

[0062] Understandably, the steps to release the latching structure 25 from the back cover 13 are as follows: an external force is applied to the pressing part 252 to move the extension section 2522 toward the straight section 2511. At the same time, the contact area between the body 2521 and the limiting wall 1351 in the limiting part gradually decreases until the body 2521 completely disengages from the limiting wall 1351. Then, the body 23 is pulled outward from the display module 1 to move the latching structure 25 away from the back cover 13, thereby releasing the connection between the latching structure 25 and the back cover 13.

[0063] In some embodiments, the back cover 13 includes a reinforcing rib 136 that enhances the structural strength of the first limiting portion 135. Exemplarily, the reinforcing rib 136 may be triangular in shape. One side of the reinforcing rib 136 is connected to the first limiting portion 135, and the adjacent side is connected to the cover body 131.

[0064] See Figure 8 and Figure 10 In some implementations, the back cover 13 includes a second limiting part 137, which is mirror-symmetrically arranged with the first limiting part 135 along the center line of the interface 141 on the signal transmission module 14. The arrangement of the second limiting part 137 makes the contours of the opposite sides of the connecting hole 15 convex. The arrangement of the second limiting part 137 makes the connecting hole 15 form a second connecting hole 152 that is mirror-symmetrical with the first connecting hole 151, so that the snap-fit ​​structure 25 in the data connection cable 2 can also be snapped and fixed to the back cover 13 through the second connecting hole 152. The first connecting hole 151 and the second connecting hole 152 are connected.

[0065] When the connector 22 is a reversible plug-in connector, it is provided with a second connection hole 152 and a first connection hole 151, so that whether the connector 22 is plugged into the interface 141 in the forward direction or in the reverse direction, there is a corresponding convex hole that cooperates with the snap-fit ​​structure 25 to ensure the connection stability and reliability between the data connection cable 2 and the display module 1, and to ensure stable signal and stable data transmission.

[0066] See Figure 6 and Figure 8 In some embodiments, the body 2521 of the snap-fit ​​structure 25 includes a connecting segment 2521a and a protrusion 2521b. An arcuate segment 2512 and an extension segment 2522 are respectively connected to opposite sides of the connecting segment 2521a, and the protrusion 2521b is disposed on the end of the connecting segment 2521a away from the arcuate segment 2512. The surface of the protrusion 2521b forms an abutment surface 2521c with the end face of the connecting segment 2521a away from the arcuate segment 2512. The protrusion 2521b increases the contact area between the abutment surface 2521c and the limiting wall 1351, thereby helping to improve the connection stability between the snap-fit ​​structure 25 and the rear cover 13.

[0067] The width of the extension section 2522 is smaller than the width of the main body 2521. When the snap-fit ​​structure 25 in the data connection cable 2 is snapped and fixed on the display module 1, the extension section 2522 can be held against the top wall 1352 of the first limiting part 135.

[0068] During the process of releasing the connection between the snap-fit ​​structure 25 and the back cover 13, the user's thumb presses the extension section 2522, causing the extension section 2522 to move closer to the straight section 2511 away from the surface of the connector 22. At the same time, the main body 2521 and the arc-shaped section 2512 connected to the main body 2521 deform along with the extension section 2522. After the external force is released, the arc-shaped section 2512, the main body 2521, and the extension section 2522 can be reset and restore their original shape by utilizing the elasticity of the arc-shaped section 2512.

[0069] In some embodiments, the end of the extension 2522 away from the body 2521 may be rounded to improve user comfort and avoid scratching the user's skin.

[0070] See Figure 6 In some embodiments, the pressing part 252 may include at least one rib 2523, which protrudes from the extension section 2522 to increase friction and improve user ease of operation. For example, three ribs 2523 are provided, spaced apart along the length of the extension section 2522. It should be noted that the protruding ribs 2523 also help to enhance the structural strength of the extension section 2522, preventing breakage of the extension section 2522 during pressing.

[0071] In some embodiments, the pressing part 252 may include a reinforcing rib 2524, which protrudes from the surface of the extension section 2522 opposite to the straight section 2511. The length direction of the reinforcing rib 2524 is the same as the length direction of the extension section 2522, so that the extension section 2522 can withstand greater longitudinal pressure and constrain the movement path of the extension section 2522, ensuring that it rotates around the fold of the arc section 2512, and preventing only the extension section 2522 from deforming while the arc section 2512 remains unaffected when pressed against it. In addition, the setting of the reinforcing rib 2524 also enhances the structural strength of the extension section 2522, improves the bending resistance and fatigue life of the extension section 2522, and prevents the extension section 2522 from deforming or breaking under long-term reciprocating motion.

[0072] See Figure 3 and Figure 10 In some embodiments, the display module 1 includes a buffer latch 4. The buffer latch 4 provides better protection for the display module 1.

[0073] Specifically, the buffer buckle 4 and the connecting hole 15 are located on the same side of the back cover 13, that is, the buffer buckle 4 is located on the side of the back cover 13 away from the lamp panel 11. The buffer buckle 4 and the connecting hole 15 are spaced apart. The buffer buckle 4 is open at both ends and hollow inside to form a receiving space 41, in which the wire 21 of the data connection cable 2 is housed.

[0074] In some embodiments, the buffer latch 4 includes an approximately C-shaped arcuate portion 43. One end of the arcuate portion 43 is connected to the back cover 13, and the other end is spaced from the surface of the back cover 13 to form a notch 42, through which the thread 21 can be smoothly accommodated in the receiving space 41.

[0075] In some embodiments, the buffer latch 4 may include a guide portion 44 disposed on the end of the arcuate portion 43 away from the cover 131, and the end of the guide portion 44 away from the arcuate segment 2512 extends in a direction away from the cover 131. The arrangement of the guide portion 44 is equivalent to a warping of the end of the arcuate portion 43 away from the cover 131, which guides the cable 21 in the data connection cable 2 into the receiving space 41, thereby helping the cable 21 to quickly enter the receiving space 41.

[0076] In some embodiments, the buffer buckle 4 includes a protruding ridge 45, which protrudes from the inner wall of the arcuate portion 43 near the cover 131. The protruding ridge 45 is connected to the inner wall of the cover 131. The protruding ridge 45 helps to enhance the structural strength of the buffer buckle 4 and prevents the buffer buckle 4 from breaking under external force.

[0077] Multiple protruding ribs 45 may be provided to further enhance the connection strength of the buffer buckle 4 on the cover 131. For example, three protruding ribs 45 are provided, and the three protruding ribs 45 are spaced apart along the width direction of the cover 131.

[0078] When the display module 1, which is used in a canopy or is tilted, is accidentally dropped from a height, the presence of the buffer buckle 4 increases the contact points between the data connection cable 2 and the display module 1. This causes the portion of the cable 21 that is away from the main body 23 to bend around the buffer buckle 4, thereby providing resistance to reduce, disperse, and buffer the impact force of the falling display module 1, thus helping to slow down the fall of the display module 1. At the same time, it also reduces the impact on the connection between the data connection cable 2 and the display module 1, preventing the data connection cable 2 from suddenly straightening and breaking the connection between the data connection cable 2 and the display module 1, thus better protecting the display module 1.

[0079] It should be noted that in this embodiment, the buffer buckle 4 can be integrally formed with the back cover 13. In other embodiments, the buffer buckle 4 can also be separately set from the back cover 13. The buffer buckle 4 can be installed on the back cover 13 by means of screwing, snap-fitting, interference fit, etc., which can be set according to actual needs.

[0080] In some embodiments, two buffer clips 4 may be provided. The two buffer clips 4 are provided on opposite sides of the connection hole 15, so that when the connector 22 in the data connection cable 2 is a reversible plug-in connector, there is a corresponding buffer clip 4 to cooperate with the data connection cable 2, so as to achieve better protection for the display module 1.

[0081] This utility model also provides a display screen, including at least one of the above-described display units 100 and a power signal processing module. The display module 1 in the display unit 100 can be electrically connected to the power signal processing module via a data connection cable 2 to enable power supply and signal transmission to the display module 1.

[0082] In this embodiment, the display unit 100 in the display screen can be fixed to the external structure by the magnetic attachment 3, forming initial protection for the display unit 100. Simultaneously, the snap-fit ​​structure 25 in the data connection cable 2 makes the connection between the data connection cable 2 and the display module 1 more secure and less prone to loosening. Furthermore, the data connection cable 2 and the buffer snap-fit ​​4 work together to form further protection for the display unit 100, effectively preventing the display unit 100 from accidentally falling to the ground.

[0083] It is important to note that in traditional displays, data connection cables are an essential component. Furthermore, the cable 21 within the data connection cable 2 possesses inherent strength. Therefore, the display of this application fully and effectively utilizes the data connection cable 2, enabling it to not only transmit signals but also provide protection. This eliminates the need for additional steel wire rope reinforcement, saving on the selection, laying, and tightening of steel wire ropes, thereby reducing costs and construction complexity. Furthermore, it effectively avoids the cumbersome installation process of screws and bolts to the external structure, saving manpower and time required for installation and improving installation efficiency.

[0084] The above embodiments are merely illustrative examples of structures. The structures in each embodiment are not fixed combinations. In the absence of structural conflicts, the structures in multiple embodiments can be arbitrarily combined and used.
