Description

Technical Field

[0001] The utility model relates to a device structure, in particular to an assembly structure for a mini light panel of a liquid crystal television, and belongs to the technical field of liquid crystal television design and manufacturing. Background Art

[0002] In the conventional mini light board design, the mini light board comes with a diffuser support frame, which is welded to the front of the mini light board. Due to the dense concentration of lamp beads, the diffuser support frame chassis is in the blank area between the lamp beads, so the outer diameter of the diffuser support frame chassis is limited. If the outer diameter of the diffuser support frame chassis is too small, the welding surface is limited, and it is easy to fall off. At the same time, due to the small outer diameter of the diffuser support frame chassis, the height of the diffuser support frame is also limited, resulting in the spacing between the light board and the diffuser plate is also limited, which has a certain impact on the optical performance. The denser the lamp beads, the greater the impact. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide an assembly structure for a mini light panel of a liquid crystal television, which has significantly reduced restrictions and is relatively reliable and firm to install.

[0004] The technical solution adopted to solve the above technical problems is: an assembly structure for a mini light board of an LCD TV, including a mini light board, on one side of which lamp beads are densely distributed, the assembly structure also includes a diffusion plate support frame and a connecting and fixing component, and an installation mechanism is arranged on the mini light board. Each diffuser plate support frame is fixed on the mini light board at a prescribed position through the installation mechanism in cooperation with the connecting and fixing component without interfering with the lamp beads on the mini light board.

[0005] Furthermore, each diffuser plate support frame includes a chassis and a support column, and the support column is vertically arranged at the geometric center of the top surface of the chassis. Each diffuser plate support frame is fixed on the mini light board through the chassis with the cooperation of the connecting fixing component and the installation mechanism.

[0006] A preferred embodiment of the above scheme is that the chassis is circular, square or elliptical, and the support columns are designed to be circular, square or elliptical in their cross sections.

[0007] Furthermore, the mounting mechanism is a plurality of through holes arranged in the blank spaces between the lamp beads on the mini light board, and the chassis of each diffuser plate support frame is fixedly connected to the side of the mini light board where the lamp beads are not arranged with the cooperation of the connecting and fixing components, and the supporting columns of each diffuser plate support frame pass through the corresponding through holes respectively.

[0008] A preferred embodiment of the above solution is that the chassis and the supporting columns are an integrally formed structure.

[0009] Furthermore, the connecting and fixing component includes a plurality of double-sided adhesive discs whose number is equal to the number of diffusion plate support frames, and each double-sided adhesive disc is respectively provided with a through hole. Each double-sided adhesive disc which is sleeved on the corresponding supporting column through the through hole is respectively bonded and connected to the top surface of the chassis and the side of the mini light panel at the corresponding position where the lamp beads are not arranged.

[0010] A preferred embodiment of the above scheme is that the assembly structure further includes a bottom plate, and a side of the mini lamp board where the lamp beads are not installed is covered in the bottom plate.

[0011] Furthermore, sinks are provided on the bottom plate at locations corresponding to the positions of the chassis, and the chassis of the diffuser plate support frames installed in place are located in the corresponding sinks.

[0019] like Figure 1 to Figure 5 The utility model shows an assembly structure for a mini light board for an LCD TV, which has significantly reduced restrictions and is relatively reliable and firm to install. The assembly structure includes a mini light board 1, on one side of which lamp beads 2 are densely distributed. The assembly structure also includes a diffusion plate support frame and a connecting and fixing component. A mounting mechanism is provided on the mini light board 1. Each diffuser plate support frame is fixedly mounted on the mini light board 1 at a specified position without interfering with the lamp beads 2 on the mini light board 1 through the mounting mechanism in cooperation with the connecting and fixing component. The technical solution provided in the present application is based on the existing mini light board, and combined with the feature that lamp beads are densely distributed on one side of the mini light board, a new assembly structure is formed by adding a diffuser plate support frame and a connecting and fixing component, and then a mounting mechanism is provided on the mini light board. During assembly, each diffuser plate support frame is fixedly mounted on the mini light board at a specified position without interfering with the lamp beads on the mini light board through the mounting mechanism in cooperation with the connecting and fixing component. This changes the installation structure in the prior art where the diffuser plate support frame needs to be directly welded to the blank space on the mini lamp board where the lamp beads are densely packed. This not only prevents the structure of the diffuser plate support frame from being limited by the too small gap between the lamp beads, but also, since the improved diffuser plate support frames in the present application are fixed on the mini lamp board at the prescribed positions by the installation mechanism and the connecting and fixing components, they do not interfere with the lamp beads on the mini lamp board. This ensures that the installation is relatively reliable and firm, thus solving the technical problem of the prior art where the installation is not firm and is easy to fall off.

[0020] Accordingly, referring to the structure of the existing diffuser support frame, and combining the structural characteristics of each component to be installed, each diffuser support frame of the present application includes a chassis 3 and a support column 4, and the support column 4 is vertically arranged at the geometric center of the top surface of the chassis. Each diffuser support frame is fixed on the mini light board 1 through the chassis 3 with the cooperation of the connecting fixing assembly and the mounting mechanism. At this time, the chassis 3 can be circular, square or elliptical, and the support column 4 can also be circular, square or elliptical in its cross section. More preferably, the chassis 3 and the support column 4 are an integrally formed structure.

[0021] As one of the main components and structures for improvement, the installation mechanism described in the present application is a plurality of through holes 5 arranged in the blank space between the lamp beads 2 on the mini light board 1. The chassis 3 of each diffuser plate support frame is fixedly connected to the side of the mini light board 1 where the lamp beads 2 are not arranged in cooperation with the connection and fixing assembly, and the support columns 4 of each diffuser plate support frame respectively pass through the corresponding through holes 5. Adapting to the installation mechanism, the connection and fixing assembly described in the present application includes a plurality of double-sided adhesive discs 9 whose number is equivalent to the number of diffuser plate support frames, and each double-sided adhesive disc 9 is respectively provided with a through hole 6. Each double-sided adhesive disc 9 sleeved on the corresponding support column 4 through the through hole 6 is respectively bonded to the top surface of the chassis 3 and the side of the mini light board 1 where the lamp beads 2 are not arranged at the corresponding position.

[0022] Furthermore, in combination with the assembly structure described in the present application, it also includes a base plate 7, and the side of the mini lamp panel 1 where the lamp beads 2 are not installed is covered in the base plate 7. Sinks 8 are also provided on the base plate 7 at positions corresponding to the positions of each chassis 3, and the chassis 3 of each diffuser plate support frame installed in place are respectively located in the corresponding sinks 8.

[0023] In summary, the use of the diffusion plate support frame assembly structure of the present application can solve the risk of the diffusion plate support frame falling off, increase the spacing between the light panel and the diffusion plate, and improve the optical performance.

[0024] The technical solution of the present application is further described below through specific embodiments:

The double-sided tape is located between the front side of the diffuser plate support frame chassis and the back side of the mini light board, and the diffuser plate support frame chassis is pasted and fixed on the mini light board. On the same mini light board, other diffusion plate support frames are pasted and fixed on the mini light board in the same way, and the mini light board is fixed on the inner surface of the back panel cavity. The chassis of the diffusion plate support frame is just in the back panel sink, and the chassis of the diffusion plate support frame is between the inner surface of the back panel cavity and the back of the mini light board; other mini light panels are assembled in the same way.

[0028] A plurality of through holes are opened in the blank areas between the lamp beads on the mini lamp board, and the through holes correspond to the support columns of the diffusion plate support frame; the inner diameter of the through holes is slightly larger than the outer diameter of the support columns, and the inner diameter of the through holes can meet any outer diameter size of the support columns.

[0029] The chassis of the diffusion plate support frame is circular or other shapes, and the outer diameter of the chassis is adjustable without restriction; there is a support column in the middle of the diffusion plate support frame, and the shape of the support column is circular or other shapes; the outer diameter of the support column is slightly smaller than the inner diameter of the through hole of the mini light panel; the height of the support column is adjustable without restriction.

[0030] The front side of the chassis of the diffusion plate support frame is pasted with double-sided tape.

[0031] A through hole is provided in the middle of the double-sided adhesive tape, and the inner diameter of the through hole is larger than the outer diameter of the support column.

[0032] There are several sinks in the back panel cavity area, corresponding to the chassis of the diffuser plate support frame, and the back of the chassis of the diffuser plate support frame is in the sink; the inner diameter of the sink is larger than the outer diameter of the chassis of the diffuser plate support frame, and the depth of the sink is equal to or slightly larger than the common thickness of the chassis of the diffuser plate support frame and the double-sided tape.

[0033] Embodiment 1

[0034] like Figures 1 to 5 The technical solution provided in this application includes a mini light panel, a diffuser support frame, a double-sided tape, and a back panel.

[0035] Specific implementation plan: peel off the release paper on one side of the double-sided tape, align the through hole of the double-sided tape with the support column of the diffusion plate support frame, pass through the support column of the diffusion plate support frame, and stick it to the front of the chassis of the diffusion plate support frame; peel off the release paper on the other side of the double-sided tape, align the support column of the diffusion plate support frame with the through hole on the back of the mini light board, pass through the through hole of the mini light board, and stick it to the back of the mini light board. The double-sided tape is between the front of the chassis of the diffusion plate support frame and the back of the mini light board, and the diffusion plate support frame is pasted and fixed on the mini light board.

Since the diffuser support frame chassis has a mini light board limiter, the height of the support column of the diffuser support frame is not affected by the chassis and the size can be adjusted at will.

[0037] The other mini light panels are assembled in the same way.

[0038] The above description is only a preferred embodiment of the present application and is not intended to limit the present application.
