[0023] Currently, display devices generally consist of a housing and independent modules. The housing houses circuit boards, a backplate, and a front panel. The independent modules contain components such as voice bars, buttons, infrared receivers, and light sensors. These independent modules are located on the bottom of the housing and are electrically connected to the internal electrical components. Because the housing and the independent module housing are relatively independent, two sets of molds are required for production, resulting in two sets of housings. The outer shell of the independent module is located on the outside of the housing, meaning its overall size is the sum of the two housing sizes. This design results in an excessively large overall size, failing to meet the demands for thin, compact, and aesthetically pleasing display devices.

[0024] This utility model proposes a decorative strip assembly.

[0025] Please see Figure 1 In one embodiment of this utility model, the decorative strip assembly 100 is used in a display device 1000 to cover an opening located at one side of the housing 200 of the display device 1000. The decorative strip assembly 100 includes a decorative strip 1 and a control device 2. The decorative strip 1 has an inner side and an outer side. The inner side of the decorative strip 1 is arranged to correspond to the interior of the housing 200 of the display device 1000. The decorative strip 1 has a sound hole 121 and a light hole 122 that penetrate its inner and outer sides. The control device 2 is installed on the inner side of the decorative strip 1. The control device 2 includes a voice module 21 and an optical signal transceiver module 22. The sound outlet 211 of the voice module 21 communicates with the sound hole 121. The light outlet of the optical signal transceiver module 22 is arranged to correspond to the light hole 122 and can transmit and receive light wave signals with the outside world through the light hole 122.

[0026] In the prior art, the control device 2 (which includes a voice module 21 and an optical signal transceiver module 22) is located on the outside of the decorative panel 1. In the technical solution of this utility model, the decorative panel 1 is installed on one side of the opening of the housing 200. By setting the control device 2 on the inside of the decorative strip 1, since the inside of the decorative strip 1 corresponds to the inside of the housing 200, the installation position of the control device 2 is located inside the cavity of the housing 200. The control device 2 is built in and encapsulated by a housing 200, achieving the technical effect of reducing the overall size. In order to facilitate the sound to propagate to the outside of the housing 200 and to receive voice commands issued by the user, a sound hole 121 is provided on the decorative strip 1, which penetrates its inside and outside. The sound outlet 211 of the voice module 21 is connected to the sound hole 121. In order for the optical signal transceiver module 22 to receive and transmit optical signal commands, a light hole 122 penetrating its inner and outer sides is provided on the decorative strip 1. The light-emitting end of the optical signal transceiver module 22 is set corresponding to the light hole 122, and can receive and transmit light wave signals with the outside world through the light hole 122. Therefore, when using a housing 200 for encapsulation, it will not affect the use of the control device 2. In addition, using a housing 200 for encapsulation reduces the costs of mold development, use, and maintenance, and from the perspective of production steps, it can also improve the production efficiency of the display device 1000.

[0027] To direct sound toward the user, or to facilitate the reception of voice commands from the user. See also Figure 1 and Figure 5 The decorative strip 1 has a first outer side, which is positioned facing the user. One end of the sound hole 121 passes through the first outer side, and the other end passes through the inner side of the decorative strip 1, ensuring that sound propagates towards the user and the display device 1000. Furthermore, since light signals propagate in a straight line, the light hole 122 must also be positioned facing the user to receive light signals. Therefore, one end of the light hole 122 passes through the first outer side, and the other end passes through the inner side of the decorative strip 1. This arrangement allows the infrared receiving component in the optical signal transceiver module 22 to better receive signals. The optical signal transceiver module 22 also includes a light-sensing component, which senses external light intensity and adaptively adjusts the screen brightness.

[0028] Based on the mounting positions and orientations of the voice module 21, optical transceiver module 22, and circuit board 23, the audio aperture 121 and optical aperture 122 are as follows: Please refer to [link / reference needed]. Figure 1The decorative strip 1 has an installation area with a bottom 11 and a side 12. The outer side of the side 12 is oriented towards the user. Generally, the bottom 11 and the side 12 are vertically aligned. The control device 2 includes a circuit board 23, which is fixedly mounted on the bottom 11 and is generally parallel to it. This arrangement facilitates installation and maintenance. The optical transceiver module 22 is mounted on the circuit board 23. The optical transceiver module 22 can be oriented towards the side 12, therefore, the optical aperture 122 is opened in the side 12 and extends through both the inner and outer sides of the side 12. However, when the voice module 21 is mounted on the circuit board 23, the sound outlet 211 of the voice module 21 faces the circuit board 23. Therefore, one end of the sound outlet 121 extends to the outside of the side portion 12, and the other end extends to the inside of the bottom portion 11. By bending the sound outlet 121 into an "L" shape, the sound transmission path is changed, so that when the sound leaves the sound outlet 121, it propagates towards the user.

[0029] For ease of installation and maintenance, the voice module 21 is located on the side of the circuit board 23 facing away from the bottom 11; and the circuit board 23 is located between the voice module 21 and the bottom 11, which will block the sound transmission. Therefore, the circuit board 23 is provided with a through hole 231 that mates with the sound hole 121 and the sound outlet hole 211 of the voice module 21.

[0030] For better reception of optical signals, in one embodiment, please refer to Figure 2 and Figure 3 The optical signal transceiver module 22 includes a lens 221. A limiting structure 13 is provided on the inner side of the side portion 12, defining a limiting region. The lens 221 is installed within the limiting region, and the optical aperture 122 is located within the limiting region. The installation position of the lens 221 corresponds to the optical aperture 122, which is more conducive to receiving optical signals. The lens 221 is limited by the limiting structure 13 to prevent it from falling out of the limiting region.

[0031] For details, please refer to Figure 2 and Figure 3The limiting structure 13 includes: a slot 131, a stop portion 132, and two limiting members 133; the slot 131 is located on the inner side of the bottom 11 for at least partial insertion of the lens 221; the inner side of the side portion 12 protrudes to form the stop portion 132, the stop portion 132 is disposed opposite to the slot 131, the slot 131 and the stop portion 132 are disposed on both sides of the width direction of the limiting area, limiting the lens 221 in the width direction of the limiting area; the two limiting members 133 are respectively disposed on both sides of the length direction of the limiting area; and are disposed corresponding to two opposite side edges of the lens 221 in the length direction of the limiting area, limiting the lens 221 in the length direction of the limiting area; the limiting member 133 is recessed on one side facing the lens 221, so that the side edge of the lens 221 can be embedded. Thus, the limiting member 133 also abuts against one side of the lens 221 in the thickness direction, and the side portion 12 and the limiting member 133 limit the thickness direction of the lens 221.

[0032] To allow the lens 221 to be inserted into the slot 131, the lens 221 includes a lens body 2211 and an extension portion 2212. (See also...) Figure 4 The lens body 2211 is used to allow light to pass through. The extension portion 2212 is disposed on the side of the lens body 2211 and is used to insert into the slot 131. In addition, the extension portion 2212 is disposed on the side of the lens body 2211 to prevent light from diffusing out from the side of the lens 221 and to prevent light leakage.

[0033] To absorb noise, produce a softer sound, and improve recognizability, the decorative strip assembly 100 also includes foam 3. (See [link to relevant documentation]). Figure 1 The foam 3 is disposed between the circuit board 23 and the bottom 11, and the foam 3 is provided with a sound hole 31 to connect the sound hole and the through hole 231.

[0034] To prevent the control device 2 from encroaching on the installation space of the original components inside the housing 200, a recess 111 is provided on the inner side of the decorative strip 1. Please refer to [link / reference]. Figures 1 to 3 The control device 2 is installed in the settling tank 111. A through hole is provided corresponding to the bottom 11 of the settling tank 111. A cantilever is provided in the through hole. The cantilever is elastically set to form a pressing part. The pressing part moves its end into the housing 200 to trigger the button switch on one side of the circuit board 23.

[0035] This utility model also proposes a display device 1000, which includes a housing 200, a display module 300, and a decorative strip assembly 100. The specific structure of the decorative strip assembly 100 is as described in the above embodiments. Since this display device 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The display device 1000 includes: a housing 200, a display module 300, and a decorative strip assembly 100; the housing 200 has a mounting cavity and a port 210 and a side opening 220 communicating with the mounting cavity, the port 210 being disposed facing the user side, and the side opening 220 being disposed on the periphery of the housing 200; the display module 300 is disposed at the port 210 of the housing 200, and the display module 300 includes a display panel 310; the decorative strip assembly 100 is mounted on the side opening 220.

[0036] In the technical solution of this utility model, please refer to Figures 6 to 8 The port 210 of the housing 200 is used to mount the display panel 310, and the bottom 11 opposite the port 210 is used to mount the back plate. A mounting bracket 400 is provided inside the housing 200 and between the display panel 310 and the back plate to mount the source driver board 500. By changing the mounting position of the source driver board 500 and using the original housing 200 for encapsulation, the source driver board 500 is avoided from being mounted on the back of the back plate, thus avoiding the need for a rear cover and achieving the technical effect of reducing the thickness of the display device 1000. Because the rear cover is eliminated, the thickness reduction of the display device 1000 is significant; even with an increased width of the decorative strip 1, the thickness is still smaller than that of the display device 1000 with a rear cover. Therefore, the width of the decorative strip 1 can be increased, thereby creating a recess 111 at the bottom 11 of the decorative strip 1 to mount the control device 2 within the recess 111.

[0037] To facilitate the centralized placement of the source driver board 500 and the voice, remote control, and button modules, and to enable centralized heat dissipation, in one embodiment, the source driver board 500 is mounted on the side of the mounting bracket 400 facing the bottom 11 of the housing 200. Furthermore, when the side panel of the housing 200 corresponding to the back panel is disassembled for maintenance (the bottom 11 side panel or peripheral side panel of the housing 200 can be made detachable), the source driver board 500 is directly opposite the line of sight of the maintenance personnel, facilitating maintenance.

[0038] Since the source driver board 500 is mounted on the side of the mounting bracket 400 facing the bottom 11 of the housing 200, and the display panel 310 is mounted on both sides of the mounting bracket 400 respectively, and the display panel 310 and the mounting bracket 400 are connected by a cable, it is necessary for the cable to bypass or pass through the mounting bracket 400. In one embodiment, the mounting bracket 400 is provided with a cable-passing hole, through which the cable passes and is limited by the cable-passing hole; in another embodiment, one side 12 of the mounting bracket 400 is provided with a cable-passing notch 410, around which the cable passes and is limited by the cable-passing notch 410. The cable-passing notch 410 limits the periphery of the cable, preventing the cable from swinging freely inside the housing 200. To ensure the source driver board 500 is stably mounted on one side of the mounting bracket 400, a limiting mounting structure is required at the mounting position for the source driver board 500 to be installed. The limiting mounting structure consists of multiple snap-fit ​​structures 420 provided on the mounting bracket 400. The multiple snap-fit ​​structures 420 limit the installation area on the mounting bracket 400. When the source driver board 500 is installed in the installation area, the multiple snap-fit ​​structures are located on the periphery of the installation area. Under the combined action of the multiple snap-fit ​​structures, the source driver board 500 is limited and fixed, preventing the source driver board 500 from falling off.

[0039] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
