[0067] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0068] To enable those skilled in the art to better understand the solutions of this application, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0069] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0070] In the description of the embodiments of this application, the words "example" or "for example" are used to indicate exemplification, illustration, or description. Any embodiment or design described as "example" or "for example" in the embodiments of this application is not to be construed as being more preferred or having more advantages than another embodiment or design. The use of the words "example" or "for example" is intended to present relative concepts in a clear manner.

[0071] Furthermore, in the embodiments of this application, "multiple" refers to two or more. Therefore, in the embodiments of this application, "multiple" can also be understood as "at least two". "At least one" can be understood as one or more, such as one, two, or more. For example, including at least one means including one, two, or more, and is not limited to which ones are included. For example, including at least one of A, B, and C, then it could include A, B, C, A and B, A and C, B and C, or A and B and C.

[0072] With the development of display technology, the size of display devices (such as LED display devices) is gradually increasing.

[0073] In related technologies, in order to reduce the space occupied by display devices when not in use or to facilitate transportation, the display screens of some display devices are designed with a foldable structure so that the display screen can be folded when the display device is not in use or to save space during transportation.

[0074] However, during transportation, the foldable structure makes the folded part of the display screen prone to shaking and collision, ultimately leading to damage to the display screen.

[0075] Therefore, in this embodiment of the application, a locking component is provided to lock or unlock the frame assembly of the display device in the folded state, which can improve the technical problem of the frame assembly being easily shaken during transportation, resulting in collision damage to the display device. More detailed examples will follow.

[0076] Please refer to Figure 1 and Figure 2This application provides a display device, including a frame assembly 400, a display assembly 300, and a locking component 500. The frame assembly 400 includes a first frame 41 and a second frame 42, which are rotatably connected to each other to have a folded state and an unfolded state. The display assembly 300 includes a first display module 31 and a second display module 32, with the first display module 31 mounted on the first frame 41 and the second display module 32 mounted on the second frame 42. Thus, by folding and unfolding the first frame 41 and the second frame 42, the first display module 31 can be folded or unfolded relative to the second display module 32 accordingly; furthermore, during use, the first display module 31 can be unfolded relative to the second display module 32 to increase the display area of ​​the display device, and during transportation or other periods of non-use, the first display module 31 can be folded relative to the second display module 32. The locking component 500 is rotatably mounted on the first frame 41; when the frame assembly 400 is in the folded state, the locking component 500 can rotate to lock or disengage from the second frame 42. Thus, during transportation, the locking component 500 can be locked to the second frame 42, thereby locking the first frame 41 and the second frame 42. When the display device needs to be used, the locking component 500 can be separated from the second frame 42 to allow the first display module 31 to unfold relative to the second display module 32.

[0077] Please continue to refer to this. Figure 3 and Figure 4 In some embodiments, the locking component 500 is provided with a first positioning structure 51, and the second frame 42 is provided with a second positioning structure 421; in the folded state, the second positioning structure 421 is located on the rotation path of the first positioning structure 51, so that the first positioning structure 51 can rotate to lock or separate from the second positioning structure 421.

[0078] For example, one of the first positioning structure 51 and the second positioning structure 421 includes a first positioning post, and the other includes a first positioning hole. In the folded state, the second positioning structure 421 is located on the rotation path of the first positioning structure 51, so that the first positioning structure 51 can rotate to engage with the second positioning structure 421.

[0079] That is, the locking component 500 can be rotated to the point where the first positioning pin is inserted into or disengaged from the first positioning hole, so that the locking component 500 can be rotated to lock or disengage from the locking seat 425.

[0080] Therefore, compared to locking the locking component 500 to the second frame 42 by means of screws, the insertion method of the first positioning post and the first positioning hole does not require the use of tools such as screwdrivers, thus making the embodiments of this application have the advantage of simple operation.

[0081] It is also understood that the first positioning structure 51 may include the first positioning post and the second positioning structure 421 may include the first positioning hole, or the first positioning structure 51 may include the first positioning hole and the second positioning structure 421 may include the first positioning post. This application embodiment does not limit this.

[0082] In some embodiments, the first frame 41 includes an adjacent first front side and a first side side 412. The first front side faces the same direction as the display surface of the first display module 31. The locking component 500 is rotatably mounted on the first side side 412, thereby avoiding the need to reserve a large area on the first front side to install the locking component 500, and thus improving the screen ratio of the first front side of the first frame 41.

[0083] For example, the first frame 41 may include a first frame body 413 and a rotating seat 414. The first frame body 413 has a first front side and a first side side 412. The rotating seat 414 is mounted on the first side side 412, and the locking member 500 is rotatably mounted on the rotating seat 414.

[0084] In some embodiments, the second frame 42 includes an adjacent second front side and a second side side 423. The second front side faces the same direction as the display surface of the second display module 32, and the second positioning structure 421 is disposed on the second side side 423. This avoids the need to reserve a large area on the second front side to accommodate the second positioning structure 421, thereby increasing the screen-to-body ratio of the second front side of the second frame 42.

[0085] For example, the second frame 42 may include a second frame body 424 and a locking seat 425. The second frame body 424 has a first front side and a first side side 412. The locking seat 425 is mounted on the first side side 412. The locking seat 425 has a second positioning structure 421.

[0086] Please continue to refer to this. Figure 5 In some embodiments, the locking member 500 includes a first top surface 52 and a first bottom surface 53 facing away from each other. A first positioning post protrudes from the end of the first bottom surface 53 away from the first frame 41. The end of the first bottom surface 53 away from the first frame 41 is inclined toward the first top surface 52.

[0087] Taking the locking component 500 installed on the upper side of the first frame 41 as an example, the end of the first bottom surface 53 away from the first frame 41 can be understood as forming an upwardly inclined first guide slope 54. Therefore, during the process of the first frame 41 rotating from the unfolded state to the folded state, the first guide slope 54 can abut against the second frame 42 (e.g., the locking seat 425 of the second frame 42). Thus, with the cooperation of the first guide slope 54, the second frame 42 drives the end of the locking component 500 away from the first frame 41 to automatically flip upward to avoid displacement. This reduces the need for the user to manually flip the locking component 500 to avoid displacement during the folding of the display device, making the folding of the frame assembly 400 more convenient. It also avoids damage caused by collision between the locking component 500 and the second frame 42, and / or avoids damage caused by collision between the locking component 500 and the second display module 32 on the second frame 42.

[0088] In some embodiments, the second frame 42 (e.g., the locking seat 425 of the second frame 42) is further provided with a guide groove 426. One end of the guide groove 426 is connected to the first positioning hole, and the other end of the guide groove 426 is an open structure, so that the first positioning post can slide along the guide groove (426) into the first positioning hole. For example, during the process of the frame assembly 400 switching from the unfolded state to the folded state, the first positioning post slides along the guide groove 426 into the first positioning hole. Thus, through the cooperation of the guide groove 426 and the first positioning post, the first positioning post can be inserted into the first positioning hole more conveniently and accurately.

[0089] For example, in the folded state, the end of the guide groove 426 away from the first positioning hole faces the first frame 41. Thus, during the process of switching the frame assembly 400 from the unfolded state to the folded state: firstly, the aforementioned first guide ramp 54 abuts against the groove end face of the guide groove 426, causing the locking member 500 to automatically flip upwards at the end away from the first frame 41; then, the frame assembly 400 continues to fold, causing the first positioning pin to slide from the end of the guide groove 426 away from the first positioning hole into the guide groove 426, and slide along the guide groove 426 to the first positioning hole; finally, the first positioning pin may be inserted into the first positioning hole by its own weight or by the user's pressure, thereby achieving locking of the frame assembly 400 in the folded state.

[0090] In some embodiments, both the first positioning hole and the guide groove 426 are formed in the locking seat 425. One end of the first positioning hole is open on the side end face of the locking seat 425 opposite to the second frame body 424, for the insertion of the first positioning pin. The guide groove 426 extends from the side end face of the locking seat 425 opposite to the second frame body 424, for the first positioning pin to slide into the first positioning hole.

[0091] In some embodiments, the free end of the first positioning post is provided with a first chamfer 55. Thus, during the process of the frame assembly 400 switching from the unfolded state to the folded state, the free end of the first positioning post can contact the edge of the bottom wall of the guide groove 426 away from the first positioning hole through the first chamfer 55, thereby guiding the first positioning post to slide more smoothly into the guide groove 426.

[0092] Please continue to refer to this. Figure 6 In some embodiments, the bottom wall of the guide groove 426 is provided with a second chamfer 427 at the end away from the first positioning hole. Thus, during the process of the frame assembly 400 switching from the unfolded state to the folded state, the free end of the first positioning post can contact the second chamfer 427, thereby guiding the first positioning post to slide more smoothly into the guide groove 426.

[0093] The above are some examples of the locking component 500 in the embodiments of this application.

[0094] In some implementations, the first display module 31 may include an LED display module, an LCD display module (Liquid Crystal Display), an OLED (Organic Light-Emitting Diode) display module, etc., and this application embodiment does not limit this.

[0095] In some implementations, the second display module 32 may include an LED display module, an LCD display module, an OLED display module, etc., and this application embodiment does not limit this.

[0096] In some embodiments, there are at least two first frames 41, which are respectively installed on opposite sides of the second frame 42. Each first frame 41 is provided with a first display module 31 and a locking component 500.

[0097] Therefore, the frame assembly 400 can also be understood as a three-fold structure, which can further increase the display area of ​​the display device through the two unfolded first frames 41, and reduce the maximum size of the display device during transportation through the two folded first frames 41.

[0098] For example, the second frame 42 is rotatably mounted on both ends of the opposite side in the horizontal direction with the first frame 41, and the first frame 41 is rotatably mounted on at least one side in the vertical direction with the locking component 500.

[0099] In some embodiments, in the folded state, the display surfaces of the first display module 31 and the second display module 32 are arranged facing each other. Therefore, it can also be understood that the display device adopts an inward folding scheme to avoid the display surfaces of the first display module 31 and the second display module 32 being exposed when folded. Thus, in the folded state, the display surfaces of the first display module 31 and the second display module 32 can be better protected.

[0100] Optionally, in the folded state, the display surfaces of the first display module 31 and the second display module 32 are set opposite to each other. Therefore, it can also be understood that the display device adopts an outward folding scheme. Thus, in the folded state, the display can be selected to be displayed by the display surfaces of the first display module 31 and / or the second display module 32 to meet the user's viewing needs for more different sizes and different scenarios.

[0101] The above are some examples illustrating the folding structure of the frame component 400 in the embodiments of this application.

[0102] Please continue to refer to this. Figure 7 In some embodiments, the display device further includes a bracket assembly 200. The frame assembly 400 is mounted on the bracket assembly 200, thereby enabling the display device to be installed or placed via the bracket assembly 200.

[0103] In some embodiments, the bracket assembly 200 includes a base 21 and a bracket 22. The bracket 22 is mounted on the base 21, and the frame assembly 400 is slidably mounted on the bracket 22. Thus, the position of the frame assembly 400 and the display component 300 on the frame assembly 400 can be adjusted by sliding the frame assembly 400 on the bracket 22, thereby meeting more user needs.

[0104] It is also understood that the frame component 400 may be a first frame 41 slidably mounted on the bracket 22, or a second frame 42 slidably mounted on the bracket 22. This application embodiment does not limit this.

[0105] In some embodiments, the support assembly 200 further includes a power source 23, which is mounted on the support 22 or the base 21 and is connected to the frame assembly 400 for driving the frame assembly 400 to slide. Thus, the position of the frame assembly 400 can be automatically adjusted by the power source 23.

[0106] It should also be noted that, since the frame component 400 is a foldable structure, on the one hand, the automatic adjustment by the power source 23 can prevent the frame component 400 from being damaged due to unreasonable force when the user pushes or lifts the first frame 41 or the second frame 42 alone; on the other hand, the automatic adjustment by the power source 23 can also prevent the user from having difficulty pushing or lifting the frame component 400, which has a large volume and weight, thereby improving the user experience.

[0107] The power source 23 may include a linear module, an electric actuator, a cylinder, etc., but this application embodiment does not limit it.

[0108] Please continue to refer to this. Figure 8 In some embodiments, the support 22 includes at least two uprights 221 and a connecting beam 222. The uprights 221 extend vertically and are slidably connected to the frame assembly 400. The connecting beam 222 connects to the at least two uprights 221 and is equipped with a power source 23. Thus, the slidable connection between the at least two uprights 221 and the frame assembly 400 improves the stability and reliability of the sliding motion of the frame assembly 400. The connecting beam 222 increases the strength of the uprights 221, further enhancing the stability and reliability of the sliding motion of the frame assembly 400.

[0109] For example, the column 221 includes a guide rail 223 extending in a vertical direction, and the frame assembly 400 is provided with a slider 43, which is slidably mounted on the guide rail 223. The guide rail 223 may include a sliding rod, etc., which is not limited in this embodiment.

[0110] In some embodiments, the connecting beam 222 includes a first connecting beam 2221 and a second connecting beam 2222 spaced apart in a vertical direction. One end of the power source 23 is mounted on the first connecting beam 2221 and the other end is mounted on the second connecting beam 2222, thereby improving the stability and reliability of the installation of the power source 23 through the first connecting beam 2221 and the second connecting beam 2222.

[0111] In some embodiments, the power source 23 can be installed in the middle of the connecting beam 222; for example, one end of the power source 23 is installed in the middle of the first connecting beam 2221 and the other end is installed in the middle of the second connecting beam 2222, so that the frame assembly 400 can be driven to slide by a single power source 23, so that the support assembly 200 has the advantages of simple structure and low cost, and the frame assembly 400 is subjected to uniform force at all points along the length of the connecting beam 222.

[0112] like Figure 7As shown, in some embodiments, the bracket 22 further includes a rear cover 24, which is connected to the first connecting beam 2221 and the second connecting beam 2222 respectively, and covers the power source 23, thereby preventing the power source 23 from being exposed and causing safety hazards.

[0113] In some embodiments, the rear cover 24 can also be connected and fixed to the two uprights 221, thereby improving the stability and reliability of the installation of the rear cover 24.

[0114] In some embodiments, the display device further includes a control box 100, which is mounted on the base 21 and electrically connected to the display assembly 300. This results in a higher degree of integration for the display device.

[0115] In some embodiments, the bracket 22 also includes a tank chain 25 mounted on the column 221, and the power cable between the control box 100 and the display component 300 is at least partially disposed within the tank chain 25, thereby providing protection for the power cable between the control box 100 and the display component 300 through the tank chain 25.

[0116] Please continue to refer to this. Figure 9 and Figure 10 In some embodiments, the control box 100 includes a box body assembly 11 and a box cover assembly 12. The box cover assembly 12 covers the box body assembly 11 to form an installation space 1111 between the box cover assembly 12 and the box body assembly 11.

[0117] Please continue to refer to this. Figure 11 In some embodiments, one of the box body assembly 11 and the box lid assembly 12 is provided with a first magnetic element 112, and the other of the box body assembly 11 and the box lid assembly 12 is magnetically connected to the first magnetic element 112. That is, the box body assembly 11 and the box lid assembly 12 are fixed by magnetic attraction, which makes the box lid assembly 12 easy to assemble and disassemble.

[0118] In some embodiments, one of the housing assembly 11 and the lid assembly 12 is provided with a second positioning post 122, and the other of the housing assembly 11 and the lid assembly 12 is pluggably connected to the second positioning post 122.

[0119] Therefore, on the one hand, during the installation of the box body assembly 11 and the box cover assembly 12, the box cover assembly 12 can be quickly positioned and initially fixed by the second positioning post 122, and then the stability and reliability of the box cover assembly 12 installation can be ensured by the first magnetic component 112; on the other hand, during the disassembly of the box body assembly 11 and the box cover assembly 12, the box cover assembly 12 can be disassembled simply by picking it up. Thus, it can be seen that the control box 100 of this embodiment, while ensuring the stability and reliability of the box cover assembly 12 installation, also has the advantage of being easy to assemble and disassemble.

[0120] Please continue to refer to this. Figure 12 In some embodiments, the number of first magnetic elements 112 can be multiple, such as two, three, four, five, six, or even twenty. This application does not limit this. Thus, multiple first magnetic elements 112 can achieve multiple connections and fixations between the lid assembly 12 and the body assembly 11, thereby improving the stability and reliability of the lid assembly 12 installation.

[0121] In some embodiments, at least a portion of the first magnetic elements 112 are arranged along the length direction of the lid assembly 12. It is understood that as the length of the lid assembly 12 increases, the stiffness of the lid assembly 12 decreases accordingly. Therefore, by arranging the first magnetic elements 112 at multiple positions along the length direction of the lid assembly 12, this embodiment of the application can provide better fixation and support for various positions along the length direction of the box assembly 11, thereby improving the stability and reliability of installation at various positions along the length direction of the box assembly 11.

[0122] For example, the lid assembly 12 may have a first magnetic element 112 at both ends and the middle along its length. Optionally, at least some of the first magnetic elements 112 may be evenly spaced along the length of the lid assembly 12, but this embodiment does not limit this.

[0123] In some embodiments, a first magnetic element 112 is provided on each side edge of the lid assembly 12 in the width direction. It is understood that, as mentioned above, as the length of the lid assembly 12 increases, the rigidity of the lid assembly 12 will decrease accordingly; therefore, providing a first magnetic element 112 on each side edge of the lid assembly 12 in the width direction can also be understood as providing a first magnetic element 112 on each long side edge of the box body assembly 11, thereby improving the stability and reliability of the lid assembly 12 during installation.

[0124] For example, the housing assembly 11 has two first long sides 1112 extending along the length direction. The two long sides are arranged opposite each other along the width direction of the housing assembly 11, and a plurality of first magnetic elements 112 are spaced apart on each first long side 1112.

[0125] Please refer to this as well. Figure 11 and Figure 12In some embodiments, a first connecting portion 1113 protrudes from the inner wall of the box assembly 11 and one of the box assembly 11. The first connecting portion 1113 has a second positioning hole 1114, and a second positioning post 122 passes through the second positioning hole 1114. Therefore, compared to the second positioning hole 1114 being formed on the outer wall of the box assembly 11 or the box cover assembly 12, the embodiments of this application can, on the one hand, avoid the second positioning hole 1114 and the second positioning post 122 being exposed and affecting the aesthetics of the control box 100, and on the other hand, reduce the number of openings on the surface of the control box 100, thereby improving the sealing effect and safety performance of the control box 100.

[0126] Please refer to this as well. Figure 11 and Figure 13 In some embodiments, the inner wall of the other of the box body assembly 11 and the box cover assembly 12 is provided with a second connecting portion 1211, and the second connecting portion 1211 is provided with a second positioning post 122. The second connecting portion 1211 is also provided with a second magnetic element 123, which is magnetically connected to the first magnetic element 112. Therefore, compared with opening holes on the outer wall of the box body assembly 11 or the box cover assembly 12 to install the second positioning post 122 and the second magnetic element 123, the embodiments of this application can reduce the openings on the surface of the control box 100, thereby improving the aesthetics, sealing effect and safety performance of the control box 100.

[0127] Specifically, one of the first magnetic element 112 and the second magnetic element 123 may be a magnet and the other may be a magnetic metal element. Alternatively, both the first magnetic element 112 and the second magnetic element 123 may be magnets. This application does not limit this.

[0128] It should be noted that, as mentioned above, one of the box body assembly 11 and the box lid assembly 12 is provided with a first magnetic element 112. Therefore, either the box body assembly 11 or the box lid assembly 12 may be provided with the first magnetic element 112. Correspondingly, the box body assembly 11 may be provided with a first connecting portion 1113 and the box lid assembly 12 may be provided with a second connecting portion 1211, or the box body assembly 11 may be provided with a second connecting portion 1211 and the box lid assembly 12 may be provided with a first connecting portion 1113. This application embodiment does not limit this.

[0129] For example, the box assembly 11 has a first long side 1112 extending along its length, and a first connecting portion 1113 is disposed on the first long side 1112. The lid assembly 12 has a second long side 1212 extending along its length, and a second connecting portion 1211 is disposed on the second long side 1212. Therefore, compared to the first connecting portion 1113 being disposed in the middle of the box assembly 11, this embodiment of the application allows the first magnetic element 112 to be closer to the sides of the box assembly 11 and the lid assembly 12, thereby preventing the sides of the lid assembly 12 from warping up, and ultimately improving the aesthetics and reliability of the lid assembly 12 during installation.

[0130] As mentioned above, in some embodiments, at least some of the first magnetic elements 112 are arranged along the length of the lid assembly 12. Therefore, multiple first magnetic elements 112 may be arranged at intervals in the first connecting portion 1113.

[0131] It should also be noted that the control box 100 may not have the first connecting part 1113 and the second connecting part 1211; correspondingly, the first magnetic element 112 and the like can be directly disposed on the inner wall of the corresponding box assembly 11 or box cover assembly 12; for example, the first magnetic element 112 can be directly installed on the first long side 1112, and this application embodiment does not limit this.

[0132] In some embodiments, the lid assembly 12 is further provided with a third magnetic element 124, which is used to magnetically connect with an external magnetic tool for the magnetic tool to attract and fix the lid assembly 12. Thus, the user can use a magnetic tool to pick up and put down the lid assembly 12 during the process of assembling and disassembling the lid assembly 12.

[0133] For example, the lid assembly 12 may include a lid 121 and a third magnetic element 124. The lid 121 includes two second long sides 1212, each of which has a second connecting portion 1211 integrally formed thereon. The third magnetic element 124 is located between the two second long sides 1212 and at the middle of the lid 121 along its length.

[0134] The third magnetic component 124 may include at least one of magnetic metal and magnet, but this application embodiment does not limit this.

[0135] It should be noted that the lid assembly 12 may also omit the third magnetic element 124. For example, the lid assembly 12 may also have a hand position (not shown in the figure) for the user to pick up, put down and hold the lid assembly 12.

[0136] In some embodiments, the control box 100 further includes a flexible connector 13. One end of the flexible connector 13 is fixed to the box body assembly 11, and the other end of the flexible connector 13 is fixed to the box cover assembly 12. The flexible connector 13 is used to limit the movement distance of the box cover assembly 12 when it is opened.

[0137] Therefore, the box assembly 11 can be prevented from being lost after the box assembly 11 is opened, or when the display device vibrates during transportation or other processes, causing the box assembly 111 to become loose.

[0138] The flexible connector 13 may include a rope or any other type of flexible connector 13, and this application embodiment does not limit it.

[0139] In some embodiments, one end of the flexible connector 13 is fixed to the first connecting portion 1113, and the other end of the flexible connector 13 is fixed to the second connecting portion 1211. Of course, the flexible connector 13 can also be connected to any other position of the box assembly 11, and the flexible connector 13 can also be connected to any other position of the lid assembly 12. This application embodiment does not limit this.

[0140] In some embodiments, the control box 100 also includes a sound-generating unit 14, thereby further improving the integration of the control box 100 by integrating the sound-generating unit 14 into the control box 100, and also reducing the maintenance difficulty of the sound-generating unit 14 by taking advantage of the easy disassembly and assembly of the cover assembly 12.

[0141] In some implementations, such as Figure 10 As shown, the housing assembly 11 has a mounting surface 1115 for mounting and fixing. The sound-emitting unit 14 is inclined to the mounting surface 1115. Taking the mounting surface 1115 of the housing assembly 11 as the bottom surface as an example, the sound-emitting surface of the sound-emitting unit 14 can be inclined upward, so that the sound waves of the sound-emitting unit 14 are reflected by the ceiling, thereby increasing the sound propagation distance.

[0142] For example, the lid assembly 12 may be inclined to the mounting surface 1115, and the sound-emitting unit 14 may be mounted on the lid assembly 12.

[0143] In some implementations, the sound-generating unit 14 may include a full-range speaker to meet audio integration requirements.

[0144] In some embodiments, the sound emission angle of the sound-emitting unit 14 in the vertical direction can be from 55° to 85°. For example, the sound emission angle of the sound-emitting unit 14 in the vertical direction can be 55°, 58°, 59.7°, 60°, 65°, 67.8°, 69.5°, 70°, 71.5°, 75°, 78.5°, 80°, or 85°, and this application embodiment does not limit this. This allows the sound waves generated by the sound-emitting unit 14 to have a larger sound field area.

[0145] In some embodiments, the sound emission angle of the sound-emitting unit 14 in the horizontal direction can be greater than or equal to 150°. For example, the sound emission angle of the sound-emitting unit 14 in the vertical direction can be 150°, 158°, 159.7°, 160°, 163.5°, 165.8°, 170°, 173.5°, 175°, or 178.5°, and this application embodiment does not limit this. This allows the sound waves generated by the sound-emitting unit 14 to have a larger sound field area.

[0146] In some implementations, such as Figure 12 As shown, the control box 100 also includes at least one of a wireless communication component 15, an infrared component 16, a button component 17, and an electrical interface 18, thereby improving the integration of the control box 100 and reducing the maintenance difficulty of components such as the wireless communication component 15, the infrared component 16, the button component 17, and the electrical interface 18 by taking advantage of the easy disassembly and assembly of the cover component 12.

[0147] In some embodiments, the sound-emitting surface of the sound-emitting unit 14 faces the first side of the control box 100. The wireless communication component 15 faces the first side of the control box 100. It is understood that the sound-emitting surface of the sound-emitting unit 14 is usually facing the user in order to transmit sound waves to the user, and therefore the wireless communication component 15 may also face the user in order to receive Bluetooth signals transmitted by the user's remote control, smart terminal, etc.

[0148] For example, both the sound-generating unit 14 and the wireless communication component 15 are mounted on the cover assembly 12.

[0149] The wireless communication component 15 may include a Bluetooth component, a WIFI (Wireless Fidelity) component, an NFC (Near Field Communication) component, and a UWB (Ultra Wide Band) component, etc., and this application embodiment does not limit it.

[0150] In some embodiments, the sound-emitting surface of the sound-emitting unit 14 faces the first side of the control box 100. The infrared component 16 faces the first side of the control box 100. It is understood that the sound-emitting surface of the sound-emitting unit 14 is usually facing the user in order to emit sound waves to the user, so the infrared component 16 can also face the user in order to receive infrared signals emitted by the user's remote control, smart terminal, etc.

[0151] For example, both the sound-emitting unit 14 and the infrared component 16 are mounted on the cover assembly 12.

[0152] In some embodiments, the sound-emitting surface of the sound-emitting unit 14 faces a first side of the control box 100. At least a portion of the button assembly 17 faces the first side of the control box 100. It is understood that since the sound-emitting surface of the sound-emitting unit 14 is generally facing the user in order to emit sound waves to the user, at least a portion of the button assembly 17 may also face the user in order to facilitate user pressing operation.

[0153] For example, the sound-generating unit 14 and at least part of the button assembly 17 are both mounted on the cover assembly 12.

[0154] Of course, some of the button components 17 and the sound-emitting unit 14 may face the same side of the control box 100, while some of the button components 17 and the sound-emitting unit 14 may face different sides of the control box 100. This application embodiment does not limit this.

[0155] In some embodiments, the sound-emitting surface of the sound-emitting unit 14 faces a first side of the control box 100. At least a portion of the electrical interface 18 faces the first side of the control box 100. It is understood that the sound-emitting surface of the sound-emitting unit 14 is generally oriented towards the user in order to emit sound waves to the user, and therefore at least a portion of the electrical interface 18 may also face the user in order to facilitate user operation.

[0156] For example, the sound-generating unit 14 and at least part of the electrical interface 18 may both be mounted on the cover assembly 12.

[0157] In some implementations, the electrical interface 18 may include a TYPA-C interface, a USB (Universal Serial Bus) interface, an aviation interface, an HDMI (High Definition Multimedia Interface), a DC (direct current) interface, etc., and this application embodiment does not limit this.

[0158] It is also understood that the electrical interface 18 may be entirely oriented toward the first side of the control box 100; or some of the electrical interface 18 may be oriented toward the first side of the control box 100, and some of the electrical interface 18 may be oriented toward other sides of the control box 100. This application embodiment does not limit this.

[0159] Please continue to refer to this. Figure 14 In some embodiments, the housing assembly 11 includes a housing 111 and a window cover 113. An installation space 1111 is formed between the housing 111 and the window cover assembly 12. The housing 111 also has a wiring hole 1116 and an operation window 1117, which are adjacent to each other and both communicate with the installation space 1111. The window cover 113 is movably installed on the housing 111 and is used to open or close the operation window 1117.

[0160] Therefore, one possible wiring method for the control box 100 is as follows:

[0161] First, open the operation window 1117; then, insert the external wire of the control box 100 into the installation space 1111 through the wiring hole 1116; next, connect one end of the wire inserted into the installation space 1111 through the operation window 1117; finally, close the operation window 1117. Therefore, the box assembly 11 of this embodiment also has the advantages of easy wiring and maintenance.

[0162] The window cover 113 can be movably installed on the box body 111 by either a rotating connection or a sliding connection; this application embodiment does not limit this.

[0163] In some embodiments, the housing assembly 11 further includes a resilient seal 114, which is mounted in the wiring hole 1116. The resilient seal 114 has a slit 1141. This allows wires to pass through the slit 1141 and extend into the control box 100, while the elasticity of the resilient seal 114 can seal the gap in the wiring hole 1116 as much as possible.

[0164] In some embodiments, the outer surface of the control box 100 may be provided with a decorative structure to enhance the aesthetics of the control box 100.

[0165] Decorative structures may include decorative patterns, decorative elements, and decorative layers, etc., and the embodiments of this application do not limit these.

[0166] like Figure 5As shown, this application embodiment also provides a locking device for a display device, the display device having a first component and a second component that are relatively movable. The locking device includes a locking seat 425, a rotating seat 414, and a locking member 500. The locking seat 425 is used to be mounted to the first component. The rotating seat 414 is used to be mounted to the second component. The locking member 500 is rotatably mounted on the rotating seat 414, so that the locking member 500 can be rotated to lock or disengage with the locking seat 425. Therefore, during the use of the display device, the first component and the second component can be easily unlocked or locked by rotating the locking member 500.

[0167] It is understood that the first component and the second component are the first frame body 413 and the second frame body 424 mentioned above, respectively. The first component and the second component can also be any other component on the display device, and this application embodiment does not limit them.

[0168] In some embodiments, the specific structures of the locking seat 425, the rotating seat 414 and the locking component 500 can be referred to the specific structures of the locking seat 425, the rotating seat 414 and the locking component 500 described above, and will not be repeated here in the embodiments of this application.

[0169] This application also provides a display device, which may include the locking device described above.

[0170] In some implementations, the specific structure of the display device can be referred to the display device described above, and will not be repeated here in the embodiments of this application.

The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application.
