[0036] There are many kinds of display devices on the market, which are widely used in conference rooms, shopping malls, outdoor display screens and other places. They integrate many functions such as screen display, speaker, communication, intelligent interaction, etc. Correspondingly, the components that make up the display devices will also be more complex. How to reasonably layout and assemble such a large number of parts to achieve high efficiency and high stability is an urgent problem that people in this industry need to solve.

[0037] In display devices, speakers are not only sound-generating devices, but also important electronic components of display devices. During installation, one of the common choices is to install the speakers on the frame of the display device. The specific method is to use a bracket or other structure to fix the electronic components, and to lock the bracket and the electronic components fixed by the bracket to the frame by means of bolts, rivets, etc., and to limit the torsion of the electronic components, ribs and multiple positioning holes are added to the frame. That is, the electronic components and the frame of the display device need to be screwed together multiple times to achieve the connection and fixation between the two. In this way, the structure of the frame of the display device is complex, the limiting method between the electronic components is cumbersome, the cost is high, and the electronic components are still at risk of displacement due to vibrations generated during operation.

[0038] To solve the above problems, please refer to Figures 1 to 3 The present application proposes a display device 1000 , which in an embodiment of the present application includes a display screen 100 , a frame 200 , an electronic component 300 and a fixing bracket 400 .

[0039] The display screen 100 may be a liquid crystal display screen or a LED display screen, and the display screen 100 may be a non-touch display screen or a touch display screen. The present application does not impose any specific restrictions on the type and specific structure of the display screen 100.

[0040] Most of the display devices 1000 are provided with a frame 200, which is arranged around the display screen 100 and stops one side of the display screen 100. The frame 200 is a rectangular frame with a certain thickness, and the cross-sectional shape can be a cross-sectional shape with high bending rigidity such as a groove-shaped, square-shaped or I-shaped structure. The frame 200 can be formed by bending a strip, or it can be formed by four strips connected end to end in sequence. In one embodiment, the frame 200 is provided with an installation cavity 220 and a sound outlet 240 connected to the installation cavity 220, and at the same time, part of the cavity wall of the installation cavity 220 is formed as a positioning portion 210. The frame 200 also encloses a limiting groove 230, and the groove opening 232 of the limiting groove 230 extends in the length direction of the frame 200. The display screen 100 is embedded in the limiting groove 230. In this way, the frame 200 can more firmly enclose and fix the display screen 100, and prevent the corners of the display screen 100 from being deformed and damaged due to bumps. The groove side wall 231 of the limiting groove 230 and the positioning portion 210 are relatively arranged in the up and down directions of the display device 1000.

[0041] The electronic component 300 is also an essential component of the display device 1000. There are many types of electronic components 300, which can provide many functional options, such as: camera components, projection components, speaker components, etc. In one embodiment of the present application, the electronic component 300 is provided with an assembly portion 310. Optionally, the electronic component 300 is a speaker 320, and the speaker 320 is one of the components in the electronic component 300 for generating a sound source, which can be used to output one or more of a low-frequency sound source, a medium-frequency sound source, and a high-frequency sound source.

[0042] Specifically, the speaker 320 includes a body 321 and a mounting bracket 322 for fixing the body 321. The body 321 of the speaker 320 is not limited to a rectangular parallelepiped, a cylinder, a sphere, etc., and is mainly set according to the installation scene. The speaker 320 is mainly suitable for the installation scene within the frame 200 of the display device 1000. Therefore, it is preferably set to a long rectangular parallelepiped shape. The mounting bracket 322 is provided with assembly parts 310 on both opposite sides along the length direction of the frame 200. Of course, the electronic component 300 can also be any other component constituting the display device 1000, and this application does not limit this.

[0043] The speaker 320 partially extends into the installation cavity 220 so that the sound emitted by the speaker 320 can be transmitted outward through the sound outlet 240. The speaker 320 is partially accommodated in the installation cavity 220, which can also prevent dust, water stains and other stains from invading the speaker 320 and affecting the working efficiency and service life of the speaker 320. Specifically, the sound outlet 240 is a plurality of pore structures arranged at intervals, and the shape can be circular, elliptical, or elongated strip holes. Compared with the traditional design, the sound outlet 240 is pore-shaped, which is more beautiful as a whole, and can effectively prevent dust and other impurities from entering the frame 200 and the speaker 320.

[0044] The fixing bracket 400 can be applied to various display devices 1000 that need to install and fix the electronic components 300, such as commercial display devices, monitors, TVs, interactive machines and other display devices 1000, and can also be applied to robots, cars and the like. It should be noted that the fixing bracket 400 is widely used in daily life or work or other special operations, and this application cannot be exhaustive. Therefore, the fixing bracket 400 of this application cannot be limited to the several cases listed above. The fixing bracket 400 of this application can be applied to various products that need to install and fix the electronic components 300. The number of the fixing brackets 400 corresponds to the number of the assembly parts 310, that is, the fixing brackets 400 can be arranged in alignment with the assembly parts 310 on both opposite sides along the length direction of the frame 200, so that both ends of the fixing bracket 400 are supported and positioned, thereby achieving the design effect of the non-cantilever type fixing bracket 400.

[0045] In one embodiment, if Figures 4 to 6 As shown, the fixing bracket 400 is made of plastic material, which has low material cost and good stability. The fixing bracket 400 includes a base portion 410 and a pressing portion 420 , a limiting portion 430 and a connecting portion 440 connected to the base portion 410 .

[0046] Among them, the base part 410 is fixedly connected to the frame 200, the pressing part 420 presses on the other side of the display screen 100 to relatively fix the display screen 100 and the frame 200, the connecting part 440 is detachably connected to the assembly part 310 to relatively fix the electronic component 300 and the frame 200, and the limiting part 430 abuts against the positioning part 210 to prevent the fixing bracket 400 and the electronic component 300 from twisting relative to the frame 200, so that the frame 200 does not need to limit the twisting of the electronic component 300 by increasing the rib position, etc., reducing materials and costs. It can be understood that the base part 410 and the pressing part 420, the limiting part 430 and the connecting part 440 can be an integrally formed profile structure, and these components can reduce the assembly process, improve the connection strength, reduce labor costs, and improve economic benefits by an integrated molding method. Of course, these components can also be connected or made by other methods, that is, they can also be welded, screwed, etc.

[0047] It is understandable that if Figure 3 and Figure 4 As shown, the fixing bracket 400 may not be provided with the pressing portion 420, that is, the fixing bracket 400 includes a base portion 410 and a limiting portion 430 and a connecting portion 440 connected to the base portion 410, the base portion is fixedly connected to the frame 200, the connecting portion 440 and the assembly portion 310 are detachably connected to fix the electronic component 300 and the frame 200 relatively, the limiting portion 430 abuts against the positioning portion 210 to prevent the fixing bracket 400 and the electronic component 300 from twisting relative to the frame 200, and thus omitting the setting of the pressing portion 420 can save costs and simplify the structure.

[0048] In addition, the display device 1 is also provided with a pressing block (not shown in the figure) for pressing the display screen 100. The pressing block is fixedly connected to the frame 200 and presses against the side of the display screen 100 that is not limited by the frame 200 to prevent the display screen 100 from tipping over to that side.

[0049] Specifically, the frame 200 is preset with a plurality of positioning holes (not shown in the figure), and the base portion 410 is also formed with a mounting hole 411, and the fixing bracket 400 is screwed and fixed to the frame 400 through the mounting hole 411. The base portion 410 is also provided with a mounting post 412, and the mounting post 412 is extended away from the connecting portion 440, and the mounting post 412 is inserted and limited with the positioning hole on the frame 200, at this time, the fixing bracket 400 can be screwed and fixed with the corresponding positioning hole on the frame 200 through the mounting hole 411, so as to fix the fixing bracket 400 on the frame 200, so as to ensure the installation stability of the fixing bracket 400.

[0050] Furthermore, the limiting portion 430 is formed into a plate shape extending in the length direction of the frame 200, which can effectively limit the electronic component 300 from twisting in the length direction of the frame 200. Of course, the limiting portion 430 can also be formed into other shapes with a certain length and width, which is not limited in this application. The limiting portion 430 extends into the installation cavity 220 and abuts against the cavity wall of the installation cavity 220. The pressing portion 420 abuts against the groove side wall 231 of the limiting groove 230 to cooperate with the limiting portion 430 to clamp the frame 200.

[0051] The pressing portion 420 includes a first pressing wall 421 and a second pressing wall 422 connected to each other. The first pressing wall 421 and the second pressing wall 422 are an integrally formed bending structure, which has a simple structure and is easy to process and form. One end of the first pressing wall 421 is connected to the base portion 410, and the other end is connected to the second pressing wall 422. The first pressing wall 421 abuts against the groove side wall 231 of the limiting groove 230. The second pressing wall 422 extends in a direction away from the limiting portion 430 and abuts against the display screen 100, so that the display screen 100 can be prevented from shifting or collapsing in the vertical direction of the second pressing wall. Compared with the previous related designs, this structure reduces the number of glass blocks, foams and screws used to limit the display screen 100. The assembly process is relatively simple and the cost is relatively low. Because it is made of plastic material, there is no need to attach foam, and it can directly contact the surface of the display screen 100 without scratching the surface of the display screen 100. At the same time, the production cost can be further reduced.

[0052] In another embodiment of the present application, it can be understood that the positioning portion 210 may not be integrated with part of the cavity wall of the installation cavity 220, but may be provided with a groove or the like on the frame 200 to avoid the installation cavity 220, and the limiting portion 430 may be inserted into the groove formed by the positioning portion 210. Conversely, the limiting portion 430 may also be provided with a groove or the like, and the positioning portion 210 may be correspondingly protruded and plugged with the groove formed by the limiting portion 430. Alternatively, the positioning portion 210 may also be formed as a rib structure that protrudes relatively toward the installation position of the fixing bracket 400 in the length direction of the frame 200, and the limiting portion 430 may be mounted on the rib structure. At this time, the length of the limiting portion 430 may be reduced in accordance with the rib structure, so that the manufacturing material of the fixing bracket 400 may be further saved. In the above embodiments, the limiting portion 430 may cooperate with the positioning portion 210 to limit the twisting of the electronic component 300 in the length direction of the frame 200, and at the same time, the second pressing wall 422 may still abut against and limit the display screen 100 adaptively. The positioning portion 210 and the limiting portion 430 may of course be arranged in any other structural form and assembly method having the above-mentioned effects, and the present application does not impose any limitation thereto.

[0053] The assembly method of the fixed bracket 400 on the frame 200 as described above, through the pressing portion 420 abutting against the groove side wall 231 of the limiting groove 230, and cooperating with the limiting portion 430 to clamp the frame 200, can enable the assembler to quickly find the installation position of the fixed bracket 400 on the frame 200 of the display device 1000, and then snap-fit ​​and fix it. This can save the assembly time of the assembler, so that the assembler can install the fixed bracket 400 efficiently and conveniently, and at the same time can reduce or eliminate the need to set corresponding positioning holes on the frame 200 and the fixed bracket 400, further reducing the manufacturing cost of the frame 200 and the fixed bracket 400. It is understandable that corresponding positioning holes can also be added to the frame 200 and the fixed bracket 400. In this way, the position of the fixed bracket 400 on the frame 200 can be determined in multiple steps through the clamping structure of the fixed bracket 400 and the positioning holes thereon corresponding to the frame 200, so as to further improve the positioning accuracy and stability of the fixed bracket 400 when it is assembled on the fixed bracket 400. The present application does not impose any restrictions on this.

[0054] In one embodiment, if Figures 6 to 8 As shown, the connection part 440 is clamped with the assembly part 310, and the connection part 440 includes a connection column 441 and a limit cap 442. One end of the connection column 441 is connected to the base part 410, and the other end is connected to the limit cap 442. The connection column 441 can be integrally formed with the base part 410 by injection molding. The assembly part 310 includes an ear plate 311, and the ear plate 311 is provided with a connection hole 3111. The connection column 441 is inserted into the connection hole 3111. The limit cap 442 abuts against the side of the ear plate 311 facing away from the base part 410 to stop the ear plate 311 in the direction of being loosened by the connection part 440. Specifically, the number of the ear plates 311 is two, and the two ear plates 311 are respectively arranged on the assembly part 310 at both ends of the mounting bracket 322 along the length direction of the mounting bracket 322, so as to avoid the mounting bracket 322 from being suspended by one arm, thereby improving the stability of the mounting bracket 322. Of course, the number of ear plates 311 and connecting columns 441 can be reasonably set according to actual needs, that is, the number of ear plates 311 and connecting columns 441 can also be correspondingly multiple, and the present application does not impose any restrictions on this.

[0055] Further, the connecting column 441 includes at least two sub-columns 4411 arranged side by side, and the limiting cap 442 includes at least two sub-blocks 4421, and one sub-block 4421 is connected to one sub-column 4411, wherein at least two sub-columns 4411 can be elastically bent so that at least two sub-blocks 4421 are close to or away from each other. Therefore, the connecting column 441 should be made of a material with good elasticity, which is suitable for being able to produce elastic deformation under the action of external force. For example, the material of the connecting column 441 can be but is not limited to elastic rubber. It can be understood that the connecting column 441 can also be set as a columnar structure with a regular shape, that is, there are no sub-columns 4411. In order to achieve the above-mentioned effect, the connecting column 441 should be made of a deformable material, such as silicone, etc. In this way, setting the connecting column 441 into a columnar body with a regular shape can reduce the process steps and reduce the production cost. This application does not limit this.

[0056] like Figure 8 and Fig. 9 As shown, during the installation process of the connecting portion 440 and the assembly portion 310, the hole wall of the connecting hole 3111 squeezes the outer wall of the connecting column 441 to deform at least two sub-columns 4411. At this time, at least two sub-blocks 4421 of the limiting cap 442 are tightened in the direction of being squeezed, that is, the sub-column 4411 and the sub-block 4421 can be passed through the connecting hole. After the connecting hole 3111 passes through the connecting portion 440 and is sleeved on the connecting column 441, the sub-column 4411 restores its deformation by itself, and the wall surface of the limiting cap 442 adjacent to the connecting column 441 is axially pressed against the side surface of the ear plate 311 away from the frame 200 to limit the axial movement of the speaker 320 along the connecting portion 440. The above structural form of the connecting column 441 does not need to use screws to lock the connecting column 441 and the assembly part 310, so there is no need to set a fixing structure such as a rivet column on the assembly part 310, which simplifies the structure of the assembly part 310, makes disassembly and assembly faster and easier, and further simplifies the manufacturing process and production costs. It can be understood that the connection method between the connecting part 440 and the assembly part 310 can be other forms, such as using a male buckle and a female buckle to achieve the buckle method, etc., and this application does not limit this.

[0057] When installing the electronic component 300 of the present application, the fixing bracket 400 can be first installed on the assembly portion 310 of the electronic component 300 through the connecting portion 440, and then the fixing bracket 400 can be fixed to the installation position of the electronic component 300 on the frame 200; or, the fixing bracket 400 can be first fixed to the installation position on the frame 200, and then the connecting portion 440 of the fixing bracket 400 is connected to the assembly portion 310 of the electronic component 300. All of the above can achieve the rapid positioning and installation of the electronic component 300 on the frame 200 through the fixing bracket 400.

[0058] In one embodiment, considering that after the connecting column 441 is passed through the connecting hole 3111, the outer wall surface of the connecting column 441 can be fitted with the hole wall surface of the connecting hole 3111, that is, the cross-sectional area of ​​the connecting column 441 is less than or equal to the hole cross-sectional area of ​​the connecting hole 3111, at this time, there is no interaction force between the outer wall surface of the connecting column 441 and the hole wall surface of the connecting hole 3111. It can be understood that in order to enhance the connection stability between the connecting portion 440 and the assembly portion 310, it is further designed that the portion of the connecting column 441 passed through the connecting hole 3111 has an interference fit with the hole wall surface of the connecting hole 3111. In order to achieve the effect of the interference fit and reduce the mutual stress caused by the interference fit between the connecting part 440 and the assembly part 310, and maintain the stability of the fixed bracket 400 and the speaker 320, the fixed bracket 400 also includes a buffer sleeve 460. The buffer sleeve 460 is made of a material with good elasticity and low cost, such as rubber. The buffer sleeve 460 is sleeved on the outside of the connecting column 441 and is located between the connecting column 441 and the wall of the connecting hole 3111 to play a buffering role. Specifically, the outer periphery of the buffer sleeve 460 is also provided with a slot 461 for the edge of the connecting hole 3111 to be inserted into. The slot 461 may be one or more, and the multiple slots 461 can be used for the fixed bracket 400 to adjust the position when it is connected to the assembly part 310, that is, when the connecting part 440 is matched with the assembly part 310, the limit cap 442 and the buffer sleeve 460 are axially pressed against each other to limit the position, thereby further playing a buffering role. As a result, the buffer sleeve 460 absorbs the vibration transmitted from the main body 321 of the speaker 320 to the fixed bracket 400, reduces the vibration caused by the main body 321 of the speaker 320 when making a sound, and reduces the risk of displacement or falling off of the speaker 320 due to the vibration.

[0059] In one embodiment, please refer again to Figure 7 The base portion 410 is a component of the fixed bracket 400 for supporting the connecting portion 440, the limiting portion 430 and the pressing portion 420. The shape of the base portion 410 is not limited here. For example, the base portion 410 can be a rectangular plate structure, or a solid block structure, etc. There is no limitation on the material of the base portion 410. Designers can choose a material with good structural strength according to their needs.

[0060] In addition, if Figure 8As shown, the fixed bracket 400 further includes a reinforcing rib 450, which has multiple reinforcing ribs 450 and is integrally formed with the fixed bracket 400, and the reinforcing rib 450 connects the first pressing wall 421, the second pressing wall 422 and the outer wall surface of the base portion 410. The reinforcing rib 450 can save the material of the fixed bracket 400, and at the same time can ensure the structural strength of the pressing portion 420, further increase the resistance strength of the pressing portion 420 to the force generated when the display screen 100 vibrates and shifts, and can guide the assembly of the fixed bracket 400 and the frame 200, and can also improve the reliability of the assembly of the fixed bracket 400 and the frame 200.
