Technical Field

[0001] This utility model relates to the field of fixed bracket technology, and in particular to a backlight module frame structure. Background Technology

[0002] The backlight module frame structure refers to a frame structure used to fix and protect the various components of the backlight module. It is usually made of materials such as plastic and provides stable support for the various components of the backlight module, so that they can be kept in the correct position and avoid changes in the relative position between the components due to external forces or other factors, thereby ensuring the normal operation of the backlight module.

[0003] In existing technologies, the frame structure of backlight modules basically uses a snap-on design to install the backlight module. The fixing points of the snaps are relatively concentrated, which makes it impossible to evenly distribute the external force on the backlight module. When certain parts of the backlight module are subjected to greater pressure, it is easy to cause local damage and shorten the product's service life. Utility Model Content

The fixing points of the buckle are relatively concentrated, which makes it impossible to evenly distribute the external force on the backlight module. Therefore, a new backlight module frame structure is proposed.

[0006] The effect achieved by the above components is that the internal threaded ring can rotate to unscrew the screw and eliminate the limitation on the fixed block, thereby allowing the fixed frame to move and the pressure frame and rubber frame to separate from the frame body.

[0007] Preferably, the arc surface of the internal threaded ring is provided with a plurality of anti-slip grooves, and the plurality of anti-slip grooves are evenly distributed on the internal threaded ring.

[0010] The effect achieved by the above components is that the telescopic rod is fixed to the connecting plate, and the connecting plate is fixed to the fixed frame.

[0011] Preferably, an L-shaped limiting plate is fixedly connected to the output end of the telescopic rod.

[0012] The effect achieved by the above components is that the movement of the L-shaped limiting plate drives the output end of the telescopic rod to output or retract.

[0013] Preferably, the arc surface of the telescopic rod is fitted with a spring, and the two ends of the spring are fixedly connected to the L-shaped limiting plate and the connecting plate, respectively.

[0014] The effect achieved by the above components is to prevent the spring from deforming during the stretching or contraction process.

[0015] Preferably, a sealing device is provided on one side of the frame. The sealing device includes four threaded rods and an assembly frame. One end of the four threaded rods is fixedly connected to the frame, and the arc surface of the threaded rods is threaded with an internal thread block.

[0019] Preferably, the assembly frame has two foolproof openings on one side.

[0020] The effect achieved by the above components is that the anti-foolproof opening is made on the assembly frame.

[0021] Preferably, the inside of the anti-foolproof opening is slidably connected with an anti-foolproof plate, and one side of the two anti-foolproof plates is fixedly connected to the frame.

[0022] The effect achieved by the above components is that the anti-foolproof plate and the anti-foolproof opening are matched.

[0023] In summary, the beneficial effects of this utility model are as follows:

[0024] In this invention, by using a fixing device, when the backlight assembly needs to be installed, the L-shaped limiting plate is pulled to eliminate the restriction on the inner threaded ring, the inner threaded ring is rotated to disengage from the screw, the restriction on the fixing frame is eliminated, the fixing frame is moved, and the installation space is released. Then, the backlight assembly to be installed is placed in the frame, and the installation is completed by reversing the above operation steps. By using a fixing device, the problem of the traditional backlight module frame structure, which basically uses a buckle design to complete the installation of the backlight module, is solved. The fixing points of the buckle are relatively concentrated, which makes it impossible to evenly distribute the external force on the backlight module.

[0025] In this invention, a sealing device is used to prevent light leakage from the back of the backlight assembly after installation. The sealing frame on the assembly frame tightly fits the back of the backlight assembly inside the frame, preventing light from leaking from the back of the backlight assembly. The sealing device solves the problem of poor light leakage prevention effect and the impact on the color performance of the backlight assembly caused by the traditional backlight module frame structure.

[0032] Reference Figure 1 , Figure 3 and Figure 5 As shown, this utility model provides a technical solution: a backlight module frame structure, including a frame 1, a fixing device 2 on one side of the frame 1, and a sealing device 3 on one side of the frame 1.

[0033] The following section will describe in detail the specific setup and function of its fixing device 2 and sealing device 3.

[0034] Reference Figure 2 As shown in this embodiment: the fixing device 2 includes four circular blocks 201. A screw 202 is fixedly connected to one end of each circular block 201. An internal threaded ring 203 is threadedly connected to the arc surface of the screw 202. One end of each of the four circular blocks 201 is fixedly connected to the frame 1. A sleeve 204 is slidably connected to the arc surface of each circular block 201. A fixing block 205 is fixedly connected to the arc surface of the sleeve 204. A fixing frame 206 is fixedly connected to the outer side of each of the four fixing blocks 205. A pressure frame 207 is fixedly connected to one side of the fixing frame 206. A rubber frame 208 is fixedly connected to one side of the pressure frame 207. This achieves the effect of allowing the internal threaded ring 203 to rotate and unscrew the screw 202, eliminating the limitation on the fixing block 205, thus allowing the fixing frame 206 to move and causing the pressure frame 207 and rubber frame 208 to detach from the frame 1. The inner threaded ring 203 has several anti-slip grooves 209 evenly distributed on its arc surface. This increases friction. Four connecting plates 210 are fixedly connected to one side of the fixed frame 206, and a telescopic rod 211 is fixedly connected to one side of each connecting plate 210. This ensures the telescopic rod 211 is fixed to the connecting plates 210, which in turn are fixed to the fixed frame 206. An L-shaped limiting plate 213 is fixedly connected to the output end of the telescopic rod 211. This allows the L-shaped limiting plate 213 to move, causing the output end of the telescopic rod 211 to extend or retract. A spring 212 is fitted onto the arc surface of the telescopic rod 211, with both ends fixedly connected to the L-shaped limiting plate 213 and the connecting plate 210, respectively. This prevents the spring 212 from deforming during extension or contraction.

[0035] Reference Figure 4 As shown, in this embodiment: the sealing device 3 includes four threaded rods 31 and an assembly frame 33. One end of each threaded rod 31 is fixedly connected to the frame 1, and an internal threaded block 32 is threadedly connected to the arc surface of each threaded rod 31. This achieves the effect of the internal threaded block 32 and the threaded rod 31 being compatible. A sealing frame 34, made of rubber, is fixedly connected to one side of the assembly frame 33. This achieves the effect of the sealing frame 34 being fixed to the assembly frame 33. Two anti-foolproof openings 35 are provided on one side of the assembly frame 33. This achieves the effect of the anti-foolproof openings 35 being provided on the assembly frame 33. Anti-foolproof plates 36 are slidably connected inside the anti-foolproof openings 35, and one side of each anti-foolproof plate 36 is fixedly connected to the frame 1. This achieves the effect of the anti-foolproof plates 36 and the anti-foolproof openings 35 being compatible.

[0036] Working principle: When installing the backlight assembly, the operator first pulls the L-shaped limiting plates 213 one by one through the fixing device 2, so that they are released from the limiting state of the internal threaded ring 203. During the pulling process, the L-shaped limiting plates 213 drive the telescopic rod 211 to extend and the spring 212 to stretch and deform. After the limiting of the internal threaded ring 203 is completely released, the internal threaded ring 203 is rotated to make it unscrew along the screw 202, thereby releasing the constraint on the fixing block 205. Then, the fixing frame 206 is pulled, which drives the fixing block 205 to move synchronously, so that the sleeve 204 slides smoothly off the round block 201 and the screw 202. At the same time, the fixing frame 206... The pressure frame 207 is moved, causing the rubber frame 208 to detach from the frame 1, thus releasing the installation space. Then, the backlight component to be installed is placed smoothly in the designated position inside the frame 1. Finally, the above operation steps are reversed, and the rubber frame 208 and the fixing frame 206 are reset in sequence, re-fixed by the internal threaded ring 203, and locked by the L-shaped limiting plate 213. The installation of the backlight component is then completed. The fixing device 2 solves the problem of the traditional backlight module frame structure, which basically uses a buckle design to install the backlight module. The fixing points of the buckle are relatively concentrated, which makes it impossible to evenly distribute the external force on the backlight module.

[0037] When it is necessary to prevent light leakage from the back of the backlight assembly after installation, the operator first aligns the assembly frame 33 with the frame 1 and moves the assembly frame 33 so that the anti-fooling opening 35 and the anti-fooling plate 36 are precisely engaged to ensure that the assembly position is accurate. Then, the internal thread block 32 is screwed and fixed along the threaded rod 31. The threaded engagement achieves a stable limit on the assembly frame 33. After the above operations are completed, the sealing frame 34 on the assembly frame 33 will be tightly attached to the back of the backlight assembly inside the frame 1, forming an effective shield, thereby preventing light from leaking from the back of the backlight assembly and ensuring the uniformity and purity of the display effect. The sealing device 3 solves the problem of poor light leakage prevention effect and the impact on the color performance of the backlight assembly caused by the traditional backlight module frame structure.
