[0019] With reference to the drawings and in terms of the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0020] As shown in the drawings, Figs. 1-3 A LCD module narrow frame light leakage buckle type front frame structure, comprising a front frame 1, the rear side of the front frame 1 is provided with a rear cover 2, the front surface of the rear cover 2 is evenly distributed with a slot 3, the outer surface of the rear cover 2 is evenly distributed with a through cavity 4, the through cavity 4 is communicated with the slot 3, the rear surface of the front frame 1 is evenly distributed with a plug 5, the rear end of the plug 5 is fixedly connected with a protruding block 6.

[0021] By adopting the above technical scheme, the front frame 1 is inserted into the slot 3 by aligning the plug 5, in the process of inserting the plug 5, the inner wall of the slot 3 pushes the protruding block 6, at this time, the plug 5 is inclined inward, when the plug 5 is completely inserted into the slot 3, the protruding block 6 is just corresponding to the through cavity 4, under the elastic force of the plug 5, the protruding block 6 is reset, so that the protruding block 6 is just inserted into the through cavity 4, thereby closing the front frame 1 and the rear cover 2.

[0022] When disassembling, the protruding block 6 can be separated from the through cavity 4 by pushing the protruding block 6 inward through the through cavity 4, so that the front frame 1 is extracted for disassembly.

[0023] Further, the area size of the front frame 1 is the same as that of the rear cover 2, and the edge thickness of the front frame 1 matches the edge thickness of the rear cover 2.

[0024] By adopting the above technical scheme, the front frame 1 and the rear cover 2 can be matched after installation.

[0025] Further, the plug 5 is made of an elastic plate body, and the thickness of the plug 5 matches the cavity thickness of the slot 3.

[0026] By adopting the above technical scheme, in the reset state of the plug 5 in the slot 3, the plug 5 can be kept flush with the inside of the rear cover 2, so that the inside of the whole frame structure is more flat.

[0027] Further, the shape of the protruding block 6 is set as a right triangle, and the thickness of the protruding block 6 matches the edge thickness of the front frame 1.

[0028] By adopting the above technical scheme, after the protruding block 6 is inserted into the through cavity 4, the protruding block 6 can be kept flush with the outside of the rear cover 2, so that the whole frame surface is more neat and tidy in the external structure observation.

[0029] Furthermore, a recessed groove 7 is provided on the rear side of the surface of the front frame 1, and a sealing gasket 8 is fixedly connected to the inner surface of the recessed groove 7.

[0030] By adopting the above technical solution, the edge of the LCD module can be completely covered and sealed by the sink 7, while the sealing gasket 8 will be tightly attached to the surface of the LCD module for sealing, thereby greatly improving the sealing effect of the edge gaps after the overall installation.

[0031] Furthermore, the sealing gasket 8 is made of elastic rubber material and covers the entire settling tank 7.

[0032] By adopting the above technical solution, the soft and elastic sealing gasket 8 can ensure that it fits the shape of the LCD module better when bonding with the LCD module, and will not scratch the LCD module by hard contact.

[0033] Working Principle: When using the narrow bezel anti-light leakage snap-on front frame structure of this LCD module, firstly, after the LCD module is connected to the electrical components in the back cover 2, the front side is placed into the recess 7 of the front frame 1. The recess 7 can completely cover and seal the edge of the LCD module, while the sealing gasket 8 will tightly adhere to the surface of the LCD module for sealing. Then, the front frame 1 uses the insert 5 to align with the slot 3 and insert it. During the insertion of the insert 5, the inner wall of the slot 3 will use the inclined surface to push the protrusion 6. At this time, the insert 5 will tilt inward. When the insert 5 is fully inserted into the slot 3, the protrusion 6 corresponds exactly with the cavity 4. Under its own elastic force, the insert 5 drives the protrusion 6 to spring up and reset, so that... The protrusion 6 is inserted into the cavity 4, thereby closing the front frame 1 and the rear cover 2. The front frame 1 carries the LCD module and the rear cover 2 for quick installation, and the LCD is firmly assembled inside the frame structure. Due to the covering of the groove 7 and the tight fit of the sealing gasket 8, light leakage through the seam can be prevented. At the same time, the soft sealing gasket 8 can also protect the LCD module. When disassembling, the protrusion 6 can be pushed inward through the cavity 4 to disengage the protrusion 6 from the cavity 4, thereby pulling out the front frame 1 for disassembly, so that the internal electrical components can be maintained. This is the working principle of the narrow bezel anti-light leakage snap-on front frame structure of the LCD module.
