[0011] In one aspect, the entire installation and disassembly process only needs to align the mask with the component to be installed and then perform a simple pushing or pulling operation, without using tools to tighten or loosen as in the traditional screw connection, thereby greatly saving time and effort, improving work efficiency, and facilitating quick disassembly and maintenance of the mask.

[0012] In another aspect, after installation, the first column body is located in the first hole section, and the second column body is located in the second hole section, so that the connecting column and the hole wall of the connecting hole form a stable nested fit, which can effectively prevent the mask from loosening or falling off due to external factors such as vibration and collision during use, and ensure the stability of the connection between the mask and the component to be installed.

[0013] Optionally, the mask is provided with a relief hole, the relief hole is arranged along the radial direction of the connecting hole and penetrates the connecting hole.

[0014] The arrangement of the relief hole improves the smoothness of the connecting column inserted into or withdrawn from the connecting hole, thereby improving the convenience of disassembly of the mask on the component to be installed.

[0015] According to another aspect of the present application, a display module includes a display piece, a connecting piece, and the mask described above, the display piece has an installation surface and a back surface arranged opposite to each other, and the mask is located on a side of the back surface close to the installation surface; the connecting piece includes a connecting body and a connecting column, the connecting body is arranged on the display piece; the connecting column is arranged on the connecting body and located on a side of the connecting body away from the back surface; the mask is detachably installed on the display piece by the connecting column inserted into or withdrawn from the connecting hole, and the display piece forms the component to be installed.

[0016] The mask is detachably mounted on the display piece by using the connecting mode of inserting or withdrawing the connecting column into or out of the connecting hole, which discards the cumbersome screw mounting and dismounting mode, and makes the mounting process simple and fast without the need of complex tools or professional skills; by using the above mounting and dismounting mode, the time required for dismounting the mask is shortened, and the working efficiency of dismounting the mask is improved, thereby helping to quickly dismount and maintain the mask.

[0017] Optionally, the connecting body has a first limiting surface, which is located between the mask and the back surface and limits the movement of the mask towards the back surface by abutting against the mask.

[0018] The above structure design not only provides clear limitation for the mounting position of the mask on the display piece, effectively prevents unnecessary movement of the mask towards the back surface after mounting, ensures the fixation of the relative position between the mask and the display piece, and avoids the collision of the mask with other components due to accidental movement. Meanwhile, the intuitive installation positioning reference is provided for the operator, when the mask abuts against the first limiting surface, it indicates that the mask has been installed in place, without the need of additional position adjustment, which simplifies the installation process and improves the installation efficiency.

[0019] Optionally, the display piece includes a mounting main plate and a plurality of LED lamp beads, the surface of the mounting main plate close to the mask is formed into a mounting surface, and the plurality of LED lamp beads are arranged at intervals on the mounting surface; the surface of the LED lamp bead away from the mounting main plate is formed into a mounting surface, and the surface of the mounting main plate away from the mask is formed into a back surface; the mounting surface is provided with a mounting groove, and the connecting piece is installed on the display piece by inserting the connecting body into the mounting groove.

[0020] The display piece has the characteristics of good display uniformity, high color richness and wide vision.

[0021] Optionally, the connecting body has an elastic clasp, and the mounting groove is a through groove; part of the structure of the elastic clasp extends out of the mounting groove and limits the movement of the connecting body towards the mask by engaging with the back surface; the connecting body also has a second limiting surface, which is located between the mounting main plate and the mask and limits the movement of the connecting body towards the back surface by abutting against the mounting surface.

[0022] On the one hand, part of the elastic hook extends out of the mounting groove and engages with the back side, restricting the movement of the connecting body toward the face shield; at the same time, the second limiting surface abuts against the mounting surface, restricting the movement of the connecting body toward the back side; the above structural design achieves bidirectional limiting, ensuring that the connecting body is firmly limited in two opposite directions after being installed on the mounting motherboard, effectively preventing the connecting body from shifting or loosening due to various external forces during use, and improving the stability of the connecting body on the mounting motherboard.

[0023] On the other hand, the connector can be installed on the display by inserting the elastic hook into the mounting slot. This installation operation is simple and intuitive, without the need for special tools or complicated operating steps, which greatly improves the installation efficiency. Especially in the process of large-scale production and assembly, it can save a lot of time and labor costs.

[0024] On the other hand, when it is necessary to disassemble the connector, simply apply appropriate external force to the elastic hook to make it elastically deform, and it can be easily pulled out of the mounting slot without damaging the motherboard or the connector itself. This provides convenience for subsequent maintenance, replacement or equipment upgrades, and reduces maintenance costs and difficulty.

[0026] The above structural design not only helps to optimize the spatial layout and reduce the size of the display module in the thickness direction, thereby reducing the overall volume of the display module, but also provides a certain degree of protection for the display components, reducing the area of ​​the display components directly exposed to the external environment.

[0027] Optionally, the connecting body has a limiting protrusion, and the groove wall of the mounting groove is provided with a limiting recess.

[0028] The matching limiting protrusions and limiting recesses effectively restrict the rotation of the connecting body on the mounting motherboard, ensuring the stability and reliability of the connecting body on the mounting motherboard and improving the smoothness of the mask being installed on the display component via the connector.

[0029] On the one hand, the one-to-one correspondence between multiple exposed through-holes and multiple LED beads not only allows the light emitted by the LED beads to be directly emitted through the corresponding exposed through-holes, reducing light reflection and scattering losses within the mask, thereby improving light extraction efficiency and making the display brighter and clearer, but also makes the installation of the mask on the display component more accurate, the operation simpler, reduces assembly time and costs, and improves production efficiency.

[0030] On the other hand, the surface of the cover away from the back is located on the side of the mounting surface away from the back, which can effectively prevent external objects from directly colliding and rubbing against the LED beads, reduce the risk of damage to the LED beads due to external impact, and improve the service life and reliability of the LED beads.

This eliminates the cumbersome screw disassembly and assembly method, making the installation process simple and quick, without the need for complicated tools or professional skills. By adopting the above disassembly and assembly method, the time required for disassembling and assembling the face mask is shortened, the work efficiency of disassembling and assembling the face mask is improved, thereby helping to quickly disassemble, assemble and maintain the face mask.

[0055] 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 that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0056] As described in the background section, a display module is a component with complete image display capabilities that can be installed and used as a standalone unit. In related technologies, a display module includes a component to be installed (such as a display element) and a cover, wherein the cover is detachably mounted to the component to be installed using connecting screws and covers the component. However, this installation method makes removing and installing the cover from the component cumbersome, hindering quick removal, installation, and maintenance of the cover.

[0057] Reference Figures 1 to 7 To solve the above-mentioned technical problems, according to one aspect of this application, an embodiment of this application provides a face mask for detachably mounting on a component to be installed. One of the face mask 200 and the component to be installed is provided with a connecting post 320, and the other is provided with a connecting hole 210. The face mask 200 is detachably mounted on the component to be installed by inserting or withdrawing the connecting post 320 into or out of the connecting hole 210.

[0058] In this embodiment, the component to be installed is the display 100, and the face mask 200 covers the component to be installed; in other embodiments, the component to be installed may also be other components to be protected by the face mask 200. The connecting post 320 may be inserted into or removed from the connecting hole 210 by means of interference fit, snap-fit, or magnetic attraction.

[0059] This application utilizes the connection method of inserting or withdrawing the connecting post 320 into or out of the connecting hole 210 to allow the face mask 200 to be detachably installed on the component to be installed. This eliminates the cumbersome screw removal and installation method, making the installation process simple and quick, without the need for complicated tools or professional skills. By adopting the above-mentioned removal and installation method, the time required for removing and installing the face mask 200 is shortened, and the work efficiency of removing and installing the face mask 200 is improved, thereby facilitating the quick removal, installation, and maintenance of the face mask 200.

[0060] Reference Figures 1 to 7 In one embodiment, there are multiple connectors 300, and the number of connection holes 210 is the same as the number of connectors 300. Each connector 300 is respectively provided with a one-to-one correspondence with a connection hole 210. This structural design enhances the stability of the mask 200 mounted on the component to be installed.

[0061] Reference Figures 1 to 7 In one embodiment, the component to be installed has a mounting surface 121 and a back surface 112 disposed opposite to each other, and a face shield 200 is located on the back surface 112 near the mounting surface 121; a connecting post 320 is disposed on the component to be installed, and a connecting hole 210 is disposed on the face shield 200.

[0062] In this embodiment, the connecting post 320 can be integrally molded onto the component to be installed, or it can be fixed onto the component to be installed by plugging, snapping, welding, magnetic attraction, or adhesive. In other embodiments, the connecting post 320 can also be disposed on the face mask 200, and the connecting hole 210 is disposed on the component to be installed.

[0063] In this application, when the face mask 200 needs to be installed on the component to be installed, the connecting post 320 is first aligned with the connecting hole 210, and then the face mask 200 is moved towards the component to be installed. Once the face mask 200 is inserted into the connecting hole 210 and installed on the component, the movement stops. When the face mask 200 needs to be separated from the component to be installed, it is directly moved away from the component to be installed. Once the face mask 200 is withdrawn from the connecting hole 210 and separated from the component, the movement stops.

[0064] On the one hand, the component to be installed is the supporting part of the mask 200, and its structure is relatively more stable. By setting the connecting post 320 on the component to be installed, the connecting post 320 can better bear the weight of the mask 200 and the possible external impact when the mask 200 is installed, reducing the risk of loosening or deformation of the connection part, thereby making the connection between the mask 200 and the component to be installed more stable and reliable.

[0065] On the other hand, during the installation process, the operator holds the face mask 200 to perform the installation operation; the connecting hole 210 is set on the face mask 200 and the connecting post 320 is set on the part to be installed. The operator can see the position of the connecting post 320 more intuitively, which makes it easier to align the connecting hole 210 on the face mask 200 with the connecting post 320 on the part to be installed, thereby improving the accuracy and efficiency of the installation and reducing the need for repeated adjustments due to misalignment.

[0066] Reference Figures 1 to 7 In one embodiment, the connecting post 320 is an elastic element and includes a first post 321 and a second post 322. The second post 322 is disposed on the first post 321 and located on the side of the first post 321 away from the back surface 112, and covers the first post 321. The connecting hole 210 includes a first hole segment 211 and a second hole segment 212 that are connected to each other. The first hole segment 211 is located on the side of the second hole segment 212 near the back surface 112 and allows the first post 321 to pass through. The hole wall of the first hole segment 211 is used to prevent the second post 322 from passing through the first hole segment 211. The second hole segment 212 allows the second post 322 to pass through.

[0067] In this embodiment, the connecting post 320 is made of a material capable of elastic deformation, such as rubber or silicone; the second post 322 is coaxially arranged with the first post 321, and the diameter of the second post 322 is larger than the diameter of the first post 321; at the same time, the second post 322 and the first post 321 are integrally molded parts to facilitate manufacturing and processing. The diameter of the second hole segment 212 is larger than the diameter of the first hole segment 211.

[0068] In this application, when the face mask 200 needs to be installed on the component to be installed, the connecting post 320 is first aligned with the connecting hole 210, and then the face mask 200 is moved toward the component to be installed. Since the connecting post 320 is an elastic element, as the face mask 200 moves, the second post 322 will retract after contacting the hole wall of the first hole segment 211, so as to be inserted into the first hole segment 211. Then, the face mask 200 is pushed toward the component to be installed until the second post 322 passes through the first hole segment 211 and enters the second hole segment 212, and the first post 321 enters the first hole segment 211. At this time, the face mask 200 will be inserted into the connecting hole 210 and installed on the component to be installed by relying on the connecting post 320.

[0069] When the mask 200 needs to be separated from the component to be installed, the mask 200 is directly moved away from the component to be installed. Since the connecting post 320 is an elastic element, as the mask 200 moves, the second post 322 will retract after contacting the wall of the first hole section 211, so as to enter the first hole section 211. Then the mask 200 continues to move away from the component to be installed until the first post 321 is pulled out from the first hole section 211 and the second post 322 is also pulled out from the first hole section 211. At this time, the mask 200 will be pulled out of the connecting hole 210 and separated from the component to be installed by relying on the connecting post 320.

[0070] On the one hand, the entire installation and disassembly process only requires aligning the mask 200 with the part to be installed and then performing a simple push or pull operation. Unlike traditional screw connections, there is no need to use tools for tedious tightening or loosening, which greatly saves time and effort, improves work efficiency, and facilitates the quick installation, disassembly and maintenance of the mask 200.

[0071] On the other hand, once installed, the first column 321 is located in the first hole section 211 and the second column 322 is located in the second hole section 212. This structure creates a stable nested fit between the connecting column 320 and the hole wall of the connecting hole 210, which can effectively prevent the mask 200 from loosening or falling off due to external forces such as vibration and collision during use, and ensure the stability of the connection between the mask 200 and the component to be installed.

[0072] Reference Figures 1 to 8 In one embodiment, the face mask 200 is provided with a clearance hole 220, which is arranged radially along the connection hole 210 and extends through the connection hole 210. The clearance hole 220 improves the smoothness of the insertion or withdrawal of the connecting post 320 from the connection hole 210, thereby improving the convenience of assembling and disassembling the face mask 200 on the component to be installed.

[0073] Reference Figures 1 to 8 According to another aspect of this application, embodiments of this application also provide a display module, which includes a display element 100, a connector 300, and the aforementioned face mask 200. The display element 100 has a mounting surface 121 and a back surface 112 disposed opposite to each other, and the face mask 200 is located on the back surface 112 near the mounting surface 121. The connector 300 includes a connecting body 310 and a connecting post 320. The connecting body 310 is disposed on the display element 100. The connecting post 320 is disposed on the connecting body 310 and is located on the side of the connecting body 310 away from the back surface 112. The face mask 200 is detachably mounted on the display element 100 by inserting or withdrawing the connecting post 320 into or out of the connecting hole 210. The display element 100 is formed as a component to be installed.

[0074] In this embodiment, the display module is a display module in an LED display screen (LED stands for Light Emitting Diode); in other embodiments, the display module may also be a display module in a liquid crystal display screen. The display component 100 is a circuit board with LED beads 120; in other embodiments, the display component 100 may also be a mounting panel. The connecting body 310 may be integrally molded onto the display component 100, or it may be fixed onto the display component 100 by plug-in, snap-fit, soldering, magnetic attraction, or adhesive methods. The connecting post 320 and the connecting body 310 are integrally molded; this structural design not only facilitates manufacturing but also ensures the overall structural strength of the connecting component 300.

[0075] This application utilizes the connection method of inserting or withdrawing the connecting post 320 into or out of the connecting hole 210 to allow the face mask 200 to be detachably installed on the display component 100. This eliminates the cumbersome screw removal and installation method, making the installation process simple and quick, without the need for complicated tools or professional skills. By adopting the above-mentioned removal and installation method, the time required for removing and installing the face mask 200 is shortened, and the work efficiency of removing and installing the face mask 200 is improved, thereby facilitating the quick removal, installation, and maintenance of the face mask 200.

[0076] Reference Figures 1 to 7 In one embodiment, the connecting body 310 has a first limiting surface 311a, which is located between the face mask 200 and the back surface 112, and restricts the face mask 200 from moving toward the back surface 112 by abutting against the face mask 200.

[0077] In this embodiment, the surface of the connecting body 310 near the connecting post 320 is in contact with the surface of the mask 200 near the back surface 112, and forms a first limiting surface 311a.

[0078] The aforementioned structural design not only provides clear constraints on the installation position of the face mask 200 on the display component 100, effectively preventing unnecessary movement of the face mask 200 towards the back surface 112 after installation, but also ensures the fixation of the relative position between the face mask 200 and the display component 100, avoiding collisions between the face mask 200 and other components due to accidental movement. Furthermore, it provides operators with an intuitive installation positioning reference; when the face mask 200 abuts against the first limiting surface 311a, it indicates that the face mask 200 is in place, requiring no further positional adjustments, thus simplifying the installation process and improving installation efficiency.

[0079] Reference Figures 1 to 8In one embodiment, the face mask 200 is provided with a clearance hole 220, which is arranged radially along the connection hole 210 and extends through the connection hole 210. The clearance hole 220 improves the smoothness of the insertion or withdrawal of the connecting post 320 from the connection hole 210, thereby improving the ease of assembling and disassembling the face mask 200 on the display component 100.

[0080] Reference Figures 1 to 9 In one embodiment, the display 100 includes a mounting motherboard 110 and a plurality of LED beads 120. The surface of the mounting motherboard 110 near the face mask 200 is formed as a mounting surface 111, and the plurality of LED beads 120 are spaced apart on the mounting surface 111. The surface of the LED beads 120 away from the mounting motherboard 110 is formed as a mounting surface 121, and the surface of the mounting motherboard 110 away from the face mask 200 is formed as a back surface 112. The mounting surface 111 is provided with a mounting groove 113, and the connector 300 is installed in the display 100 by being inserted into the mounting groove 113 through the connector body 310.

[0081] In this embodiment, the mounting motherboard 110 is a PCB (Printed Circuit Board); the LED beads 120 are fixedly mounted on the mounting surface 111, and transparent adhesive is filled between two adjacent LED beads 120 to protect them. The connecting body 310 can be inserted into the mounting slot 113 by interference fit, snap-fit, or magnetic attraction.

[0082] The display component 100 features good display uniformity, high color richness, and a wide viewing angle. Meanwhile, the mounting surface 111 is provided with a mounting groove 113, allowing the connector 300 to be directly inserted into the mounting groove 113 via the connecting body 310 to be installed on the display component 100. This installation method is simple and direct, eliminating the need for complex welding or other cumbersome installation processes, greatly improving assembly efficiency and reducing assembly costs, especially in large-scale production where its advantages are significant.

[0083] Reference Figures 1 to 9 In one embodiment, the connecting body 310 has an elastic hook 312 and the mounting groove 113 is a through groove; a portion of the elastic hook 312 extends out of the mounting groove 113 and restricts the connecting body 310 from moving toward the face mask 200 by engaging with the back surface 112; the connecting body 310 also has a second limiting surface 313a, which is located between the mounting motherboard 110 and the face mask 200 and restricts the connecting body 310 from moving toward the back surface 112 by abutting against the mounting surface 111.

[0084] In this embodiment, the connecting body 310 is made of a material capable of elastic deformation, such as rubber or silicone. The connecting body 310 is a one-piece molded part and includes a connecting body 311, a connecting body 311, and a plurality of limiting blocks 313. Elastic hooks 312 are provided on the connecting body 311 and located on the side of the connecting body 311 closest to the back surface 112. The surface of the connecting body 311 away from the back surface 112 abuts against the face mask 200 and forms a first limiting surface 311a. The plurality of limiting blocks 313 are evenly spaced along the circumference of the connecting body 311, and the surface of the limiting blocks 313 closest to the back surface 112 abuts against the mounting surface 111 and forms a second limiting surface 313a. Furthermore, to enhance the stability of the connector 300 mounted on the display 100, two elastic hooks 312 are provided, and the two elastic hooks 312 are symmetrically arranged along the axial direction of the connecting body 310.

[0085] On the one hand, part of the elastic hook 312 extends out of the mounting groove 113 and engages with the back surface 112, restricting the movement of the connecting body 310 toward the faceplate 200; at the same time, the second limiting surface 313a abuts against the mounting surface 111, restricting the movement of the connecting body 310 toward the back surface 112; the above structural design achieves bidirectional limiting, ensuring that the connecting body 310 is firmly limited in two opposite directions after being installed on the mounting motherboard 110, effectively preventing the connecting body 310 from being displaced or loosened due to various external forces during use, and improving the stability of the connecting body 310 on the mounting motherboard 110.

[0086] On the other hand, the connector 300 can be installed on the display component 100 by inserting the elastic hook 312 into the mounting slot 113. This installation operation is simple and intuitive, and does not require special tools or complicated operating steps, which greatly improves the installation efficiency. Especially in the process of large-scale production and assembly, it can save a lot of time and labor costs.

[0087] On the other hand, when it is necessary to disassemble the connector 300, simply apply appropriate external force to the elastic hook 312 to make it elastically deform, and it can be easily pulled out from the mounting slot 113 without damaging the mounting motherboard 110 and the connector 300 itself. This provides convenience for subsequent maintenance, replacement or equipment upgrades, and reduces maintenance costs and difficulties.

[0088] Reference Figures 1 to 10 In one embodiment, the display module further includes a mounting member 400. The surface of the mounting member 400 is provided with a receiving groove 410. A portion of the structure of the display member 100 passes through the receiving groove 410, and the back side 112 is in contact with the bottom of the receiving groove 410. The bottom of the receiving groove 410 is provided with a receiving recess 420, and a portion of the structure of the elastic hook 312 passes through the receiving recess 420.

[0089] The above structural design not only helps to optimize the spatial layout and reduce the size of the display module in the thickness direction, thereby reducing the overall volume of the display module; it also provides a certain degree of protection for the display component 100, reducing the area of ​​the display component 100 directly exposed to the external environment.

[0090] Reference Figures 1 to 3 , Figure 11 as well as Figure 12 In one embodiment, the connecting body 310 has a limiting protrusion 314, and the groove wall of the mounting groove 113 is provided with a limiting recess 114. The connecting body 310 is inserted into the limiting recess 114 through the limiting protrusion 314 and is restricted to rotate within the mounting motherboard 110.

[0091] In this embodiment, the limiting protrusion 314 is a limiting protrusion, which is disposed on the circumferential surface of the connecting body 311 and located on the side of the limiting block 313 near the back surface 112; the limiting recess 114 is a limiting groove, with the limiting protrusion 314 passing through and fitting into the limiting recess 114. In other embodiments, the limiting protrusion 314 may also be disposed on the groove wall of the mounting groove 113, and the limiting recess 114 may be disposed on the connecting body 310. Furthermore, to enhance the stability of the connecting body 310 on the mounting motherboard 110, there are two limiting protrusions 314, which are symmetrically arranged along the axial direction of the connecting body 310.

[0092] The limiting protrusion 314 and limiting recess 114 used in conjunction can effectively restrict the rotation of the connecting body 310 on the mounting motherboard 110, ensuring the stability and reliability of the connecting body 310 on the mounting motherboard 110, and improving the smoothness of the mask 200 being installed on the display 100 through the connector 300.

[0093] Reference Figure 4 , Figure 8 as well as Figure 9 In one embodiment, the face mask 200 is provided with a plurality of exposed through holes 230, the number of exposed through holes 230 being the same as the number of LED beads 120, and the plurality of LED beads 120 being respectively provided in a one-to-one correspondence with the plurality of exposed through holes 230; the surface of the face mask 200 away from the back surface 112 is located on the side of the mounting surface 121 away from the back surface 112.

[0094] In this embodiment, the mask 200 completely covers the mounting surface 111. On one hand, the multiple exposed through-holes 230 are arranged one-to-one with multiple LED beads, allowing the light emitted by the LED beads to directly pass through the corresponding exposed through-holes 230, reducing light reflection and scattering losses within the mask 200, thereby improving light extraction efficiency and making the display brighter and clearer. Simultaneously, it also makes the installation of the mask 200 on the display component 100 more accurate, simplifies operation, reduces assembly time and costs, and improves production efficiency.

[0095] On the other hand, the surface of the face shield 200 away from the back surface 112 is located on the side of the mounting surface 121 away from the back surface 112, which can effectively prevent external objects from directly colliding and rubbing against the LED beads, reduce the risk of damage to the LED beads due to external impact, and improve the service life and reliability of the LED beads.

[0096] Reference Figures 1 to 12 According to another aspect of this application, embodiments of this application also provide a display device, which includes the display module described above.

[0097] In this embodiment, the display device is an LED display screen (LED stands for Light Emitting Diode); in other embodiments, the display device may also be a liquid crystal display screen.

[0098] This application utilizes the connection method of inserting or withdrawing the connecting post 320 into or out of the connecting hole 210 to allow the face mask 200 to be detachably installed on the display component 100. This eliminates the cumbersome screw removal and installation method, making the installation process simple and quick, without the need for complicated tools or professional skills. By adopting the above-mentioned removal and installation method, the time required for removing and installing the face mask 200 is shortened, and the work efficiency of removing and installing the face mask 200 is improved, thereby facilitating the quick removal, installation, and maintenance of the face mask 200.
