Therefore, when the panel bracket 12 and the middle frame 13 are required to be connected, the universal positioning point 131 is only required to be matched with the combining piece 121. In the present embodiment, preferably, the universal positioning point 131 is a cambered pit formed by recessing the surface of the middle frame 13 toward the direction away from the panel bracket 12, and the coupling member 121 is a protrusion toward the middle frame 13, so that the coupling member 121 can be snapped into the universal positioning point 131 and be adapted to the universal positioning point 131.

The PCB board 14 is provided with a control button 141, and the middle frame 13 is provided with a corresponding through hole 132, so that the control button 141 can pass through the through hole 132 and be exposed out of the front surface of the middle frame 13, and when the metal panel 11 is pressed, the panel bracket 12 can press the control button 141 on the PCB board 14. The through hole 132 may be provided with a button film 133, and the control button 141 passes through the through hole 132 to abut against the button film 133.

The mating arrangement of the gimbaled point 131 and the coupler 121 may preferably be in the following manner:

The metal panel 11 comprises one or more control members 111 and accordingly also one or more panel brackets 12, each control member 111 being fixedly connected to a respective one of the panel brackets 12. Each control 111 may control at least three control buttons 141 on the PCB board 14, each control button 141 corresponding to an edge position of the corresponding control 111, respectively. As in the present embodiment, four control buttons 141 are controlled for one control member 111, the four control buttons 141 corresponding to both sides of both ends of one control member. When one of the edges of the control member 111 is pressed, the coupling member 121 is inclined at a certain angle to the pressed position with the universal positioning point 131 as a fulcrum, so that the control member 111 can be pressed to the control button 141 on the pressing side, and the position of the control member 111 corresponding to the other control buttons 141 is slightly tilted, so that no misoperation is caused. Each control member 111 corresponds to one gimbaled point 131, and each gimbaled point 131 corresponds to the middle of the control member 111. Preferably, each control 111 controls 3 or 4 control buttons 141. Preferably, a certain gap is formed between the universal positioning point 131 and the combining piece 121, so that the combining piece 121 and the universal positioning point 131 can freely slide without clamping.

The metal bracket 2 is arranged between the panel main body 1 and the bottom box 3, the metal bracket 2 is provided with a hollow part 21 which is hollowed out, and the panel 1 and the bottom box 3 can be combined by arranging the hollow part 21. The surface of the metal bracket 2 is provided with screw holes 22 so that the metal bracket 2 can be fixed to a wall.

Referring to fig. 6, the base case 3 includes a base case upper cover 31, a base case lower cover 32, and a power supply device 33, and the power supply device 33 is disposed in a cavity formed between the base case upper cover 31 and the base case lower cover 32.
