[0037] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0038] See also Figures 1 to 6 As shown, an embodiment of the utility model discloses a support frame, which is mainly used in the technical field of direct-down display devices. In addition to TV modules, it can also be used in display devices such as desktop monitors, interactive all-in-one machines, smart blackboards, commercial display TVs, and advertising machines. The display device is provided with a back panel and a diffusion plate spaced apart from the back panel, and the support frame is used to support the diffusion plate on the back panel.

[0039] The support frame has the following two structural forms:

[0040] Embodiment 1:

[0041] In this embodiment, the support frame includes a base 10 and a support part 20. The support part 20 is connected to the base 10 through a secondary injection molding process. The base 10 is used to be installed on the mounting hole of the back panel in the display device. The base 10 is made of white opaque material. The base 10 can close the mounting hole on the back panel to prevent light from leaking from the mounting hole. It has light-shielding properties to improve the optical light leakage and streak effects in the display device. At the same time, the base 10 can also reflect the light emitted by the light source in the display device.

[0042] The support part 20 is made of a transparent material, and includes an elastic buffer 21 and a support column 22 for abutting against the diffusion plate in the display device. The support part 20 has good light transmittance. The elastic buffer 21 is connected to the base 10 and is enclosed with the base 10 to form an annular structure 30. The support column 22 is fixed on the side of the elastic buffer 21 away from the base 10. When the diffusion plate is under pressure due to external force, the elastic buffer 21 will deform, and the annular structure 30 will deform to provide elastic buffering for the support column 22, thereby reducing the deformation of the support column 22 and ensuring the strength and toughness of the support frame. The support frame integrates the effects that originally needed to be achieved through the assembly of multiple materials, improves the optical effect in the display device, and plays a good role in reducing material and labor costs.

[0043] In this embodiment, the base 10 includes a shading disk 11, a support rod 12 and an assembly plate 13 located below the shading disk 11. The shading disk 11 and the assembly plate 13 are both arranged horizontally, and the support rod 12 is arranged vertically. One end of the support rod 12 is vertically connected to the shading disk 11, and the other end of the support rod 12 is vertically connected to the assembly plate 13. Both ends of the elastic buffer 21 are connected to the shading disk 11, and the elastic buffer 21 and the shading disk 11 are enclosed to form the annular structure 30. During specific assembly, since the shading disk 11 is a disc, the area of ​​the shading disk 11 is larger than the area of ​​the assembly plate 13, the shading disk 11 is located between the back plate and the diffuser, the support rod 12 is located in the mounting hole of the back plate, and the assembly plate 13 is installed on the side of the back plate away from the diffuser, and the shading disk 11 blocks the mounting hole of the back plate and can reflect the light emitted by the light source in the display device.

[0044] At least one hook 111 is protruded from both ends of the top of the shading disk 11, and at least one slot 211 is provided at both ends of the elastic buffer 21. The number of the hooks 111 and the slots 211 are both two, and the hooks 111 are connected to the corresponding slots 211. The structure in which the hooks 111 and the slots 211 are assembled between the base 10 and the support part 20 not only meets the requirements of the support frame's anti-twisting deformation and anti-fracture strength, but also meets the effect of rapid demolding during injection molding.

[0045] In this embodiment, during the production process of the support frame, the base 10 structure of the lower part of the support frame can be first injection molded, and the molded base 10 is then placed in a secondary injection mold, and then the structure of the upper support part 20 is injection molded for a second time. The base 10 is made of white opaque material, and the support part 20 is made of transparent material. The support frame molded by two-color injection molding adopts the "inverted trapezoidal" inner wrapping and nesting structural principle in the transparent and white injection splicing area, that is, the hook 111 is an "inverted trapezoidal" structure, and the width of the "inverted trapezoidal" hook 111 gradually decreases, which can effectively achieve the horizontal, vertical and lateral limiting and tightening effects between the base 10 and the support part 20, thereby enhancing the stability, anti-twisting and anti-extrusion fracture strength of the support frame, and at the same time, it can also ensure that the secondary injection molded support frame can be quickly demolded.

[0046] The upper part of the two-color injection-molded support frame uses transparent material to achieve good optical light transmittance in the display device, and the lower part uses white opaque material to improve the optical light leakage and streaks in the display device, thereby ensuring the supporting function and optical effect characteristics of the original support frame.

[0047] The assembly plate 13 includes a base plate 131 and two positioning protrusions 132 for clamping with the back plate. The two positioning protrusions 132 are both protruding on the side of the base plate 131 facing the shading disk 11. The support rod 12 is connected to the base plate 131. The support rod 12 is located between the two positioning protrusions 132. A plurality of corresponding assembly holes are also provided on the back plate. When assembling the support frame, the two positioning protrusions 132 are respectively clamped in two of the assembly holes to prevent the support frame from rotating during use.

[0048] In some embodiments, the assembly plate 13 is also provided with at least two buffer grooves 133 for enhancing the flexibility of the base plate 131. In this embodiment, the number of the buffer grooves 133 is two. The buffer grooves 133 are provided on the base plate 131. The buffer grooves 133 are located between the positioning protrusions 132 and the support rod 12. The base plate 131 can realize a bending function through the buffer grooves 133 so as to accurately assemble the positioning protrusions 132 on the assembly holes.

[0049] In this embodiment, the elastic buffer 21 includes two first straight plates 212 that are oppositely arranged and vertically connected to the base 10, two first curved plates 213 that are oppositely arranged, and a recessed portion 214 that is recessed toward one side of the base 10. The two ends of the recessed portion 214 are respectively connected to one end of the two first curved plates 213. The first straight plate 212 is vertically arranged, and the other end of the first curved plate 213 is connected to the base 10 through the first straight plate 212. The recessed portion 214 is located in the middle position of the elastic buffer 21 away from the base 10. The support column 22 is connected to the recessed portion 214. When the support column 22 is squeezed, the elastic buffer 21 bears and offsets part of the force through its own curved elastic outer wall, thereby reducing the deformation of the support column 22. The slot 211 is arranged on the first straight plate 212. The elastic buffer 21 can also be other structural forms.

[0050] In some embodiments, the recessed portion 214 includes two oppositely disposed second curved plates 2141 and a second straight plate 2142 disposed parallel to the shading disk 11 in the base 10, one end of the second curved plate 2141 is connected to the first curved plate 213, and the other end of the second curved plate 2141 is connected to the second straight plate 2142, and the support column 22 is vertically connected to the middle part of the second straight plate 2142 so that the force on the support column 22 is more balanced when pressed downward.

[0051] The support column 22 includes a support plate 221 and a top plate 222. One end of the support plate 221 is connected to the top plate 222, and the other end of the support plate 221 is connected to the elastic buffer 21. The outer circumferential size of the top plate 222 gradually decreases from the end close to the support plate 221 to the end away from the support plate 221. The force borne by the tip of the support column 22 can be quickly transmitted to the elastic buffer 21, causing the elastic buffer 21 to undergo elastic deformation, thereby reducing the deformation of the tip of the support column 22.

[0052] Embodiment 2:

[0053] Please read further Figures 7 to 12 As shown, the difference between Example 2 and Example 1 lies in the different structure of the support portion 20 and the different position of the hook 111 on the shading disk 11, but the functions of the two support portions 20 are the same. When the diffuser plate is subjected to external pressure, the elastic buffer 21 in the support portion 20 will deform to provide elastic buffering to the support column 22, thereby reducing deformation of the support column 22 and ensuring the strength and toughness of the support frame.

[0054] Specifically, the elastic buffer 21 includes two third curved plates 215 arranged opposite to each other, two third straight plates 216 arranged opposite to each other and parallel to the base 10, and a fourth straight plate 217 located between the two third straight plates 216. The fourth straight plate 217 is also parallel to the base 10. The thickness of the fourth straight plate 217 is greater than that of the third straight plate 216. Both ends of the fourth straight plate 217 are respectively connected to one end of the two third straight plates 216. The other end of the third straight plate 216 is connected to the base 10 through the third curved plate 215. The fourth straight plate 217 is located in the middle of the elastic buffer 21 away from the base 10. The support column 22 is connected to the fourth straight plate 217. When the support column 22 is squeezed, the elastic buffer 21 can bear and offset part of the force, thereby reducing the deformation of the support column 22. The card slot 211 is provided on the third curved plate 215. The two hooks 111 on the shading disk 11 are respectively provided on the two side ends of the shading disk 11 according to the positions of the corresponding card slots 211.

[0055] The outer circumferential dimension of the support column 22 gradually decreases from the end close to the elastic buffer 21 to the end away from the elastic buffer 21. The force borne by the tip of the support column 22 can be quickly transmitted to the elastic buffer 21, causing the elastic buffer 21 to undergo elastic deformation and reducing the deformation of the support column 22.

[0056] The utility model also discloses a display device, including a back panel, reflective paper, a light bar, a diffuser plate, an optical film and a plurality of support frames as described above, wherein the back panel, the reflective paper, the light bar, the diffuser plate and the optical film are arranged in sequence from bottom to top, the back panel is provided with a plurality of mounting holes, the support frame is mounted on the mounting holes, the top of the support frame supports the diffuser plate, the reflective paper is mounted on the back panel by means of double-sided tape, the reflective paper and the support frame are staggered, and the light bar is suspended on the reflective paper at intervals.

[0057] The support frame has the following beneficial effects:

[0058] 1. The base 10 and the support part 20 are formed by a secondary injection molding process, and the joint area adopts the inner wrapping and nesting structural principle, which not only enhances the stability, anti-twisting and anti-extrusion fracture strength of the support frame, but also improves the optical picture spots, light leakage and other defects in the display device, and also plays the role of supporting the diffusion plate.

[0059] 2. The support frame integrates the functions that can only be achieved by assembling two or three materials in the past. The functions that can be achieved by the support frame made of a single material replace the effects of assembling multiple materials, which can not only simplify the operation process, but also play a good role in reducing costs.

[0060] To sum up, the support part 20 of the support frame in the utility model is made of transparent material, and the base 10 is made of opaque material. When the support frame is installed on the mounting hole of the back plate, there is no need to install reflective sheets and screws. The operation method is simple and the operation time is short. The support part 20 is connected to the base 10 through a secondary molding process. The support frame can replace the assembly effect of multiple materials, which plays a good role in reducing the cost of display equipment, enhances the stability of the support frame, and resists distortion and extrusion fracture strength. At the same time, it can also improve the picture patterns, light leakage and other undesirable phenomena on the display device.

[0061] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention.
