[0095] The first buckle 410 includes a protruding portion 411 protruding from the bottom surface of the pressure plate 400, and a buckle portion 412 protruding from the protruding portion 411; the buckle portion 412 extends from the protruding portion 411 along the left and right directions away from the pressure plate 400; the buckle portion 412 extends into and is limited in the first buckle hole 212 to limit the movement of the pressure plate 400.
[0096] In one embodiment, the second buckle 420 includes an elastic section 421 extending downward from the bottom surface of the pressure plate 400, and a hook section 422 protruding from the elastic section 421; the hook section 422 extends from the elastic section 421 along the left and right direction away from the pressure plate 400, and the hook section 422 is engaged in the second clamping hole 213.
[0097] In one embodiment, the two buckles at both ends of the pressing plate 400 are first buckles 410 , and two first buckle holes 212 are provided on the corresponding light guide member 200 .
[0098] In another embodiment, the two buckles at both ends of the pressing plate 400 are second buckles 420 , and two second buckle holes 213 are provided on the corresponding light guide member 200 .
[0099] In this embodiment, a protruding limiting step 214 is formed on the front side wall of the accommodating cavity 210 , and a protruding limiting protrusion 430 is formed on the front end of the pressing plate 400 , and the limiting protrusion 430 abuts against the lower end of the limiting step 214 .
[0100] A protruding reinforcing rib 440 is formed on the bottom surface of the pressing plate 400, and the limiting protrusion 430 protrudes from the front side of the reinforcing rib 440 to enhance the structural strength of the pressing plate 400 and the limiting protrusion 430. The reinforcing rib 440 extends in the left-right direction.
[0101] The button protrudes from the front side or rear side of the remote control panel 300; a protruding abutting rib 460 is formed on the bottom surface of the pressure plate 400; the abutting rib 460 abuts against the upper end of the button to prevent the position of the button on the remote control panel 300 from changing, thereby effectively ensuring the reliability of the button.
[0102] A disassembly position is formed on the pressing plate 400, and the rear end of the disassembly position is close to the rear end of the remote control panel 300. The pressing plate 400 has a concave cavity 450 formed on the bottom surface of the disassembly position. The concave cavity 450 extends backward through the rear end of the pressing plate 400. The setting of the concave cavity 450 facilitates the disassembly of the pressing plate 400.
[0103] In the present invention, the left and right side walls of the accommodating cavity 210 are provided with mounting grooves 211 extending in the vertical direction, and the length direction of the remote control panel 300 is parallel to the extending direction of the light guide 200; the remote control panel 300 is arranged in the vertical direction, and the left and right ends of the remote control panel 300 are vertically inserted in the mounting grooves 211. The remote control panel 300 is vertically inserted on the light guide 200, so that the thickness of the light guide 200 in the front-to-back direction can be set thinner to adapt to the thickness of the display device in the front-to-back direction.
[0104] A button 220 is provided on the bottom surface of the light guide 200, and the button 220 abuts against the button on the remote control panel 300; the pressing plate 400 is limited on the light guide 200, and the pressing plate 400 is pressed on the top of the remote control panel 300 to press the remote control panel 300 into the installation groove 211. When the case presses the button on the remote control panel 300, the pressing of the pressing plate 400 on the remote control panel 300 effectively prevents the remote control panel 300 from moving upward, thereby ensuring the stability and reliability of the remote control panel 300 in the vertical direction.
