In order to explain the technical contents of the present invention in detail, specific examples will be given below.
In this embodiment, the light leakage prevention structure includes two key sheets 10, that is, a first key sheet 101 and a second key sheet 102, the joint side of the first key sheet 101 is provided with a joint opening 12, and the joint side of the second key sheet 102 is provided with a convex edge 11. The lower end surfaces (i.e., the back surfaces) of the first key sheet 101 and the second key sheet 102 are provided with card slots 15. Meanwhile, the key holder 20 is provided with a rotating shaft 23 matched with the slot 15. When the slots 15 of the first key sheet 101 and the second key sheet 102 are matched with the rotating shaft 23 of the key holder 20, the first key sheet 101 and the second key sheet 102 can swing within a certain range by using the rotating shaft 23 as a fulcrum.
The PCB 30 is provided with an indicator lamp 32 and four tact switches 31, the key support 20 is provided with a light guide hole 22 and four pressing pieces 21, the light guide hole 22 is located above the indicator lamp 32, the pressing pieces 21 are in one-to-one correspondence with the tact switches 31, and the pressing pieces 21 are movably abutted against the tact switches 31. The two pressing members 21 are a group and matched with a key board 10, and the two pressing members 21 in the same group are respectively arranged at two sides of the rotating shaft 23. When one side of the key sheet 10 swings down along the rotation shaft 23, the key sheet 10 presses down the pressing piece 21 on the side, so that the pressing piece 21 abuts on the tact switch 31, thereby activating the tact switch 31. Similarly, when the key sheet 10 swings to the other side, the tact switch 31 on the other side is activated.
The light emitted from the indicator lamp 32 is transmitted upward along the light guide hole 22, and the light scattering space is limited because the light blocking wall 221 is formed around the light guide hole 22. When the light reaches the lower end surface of key sheet 10, it is diffused by diffusion film 13, so that the light is concentrated at light transmission hole 14. Meanwhile, according to the principle that light travels along a straight line, a corner structure is formed between the first key board 101 and the second key board 102 through the convex edge 11 and the lap joint 12, so that light is diffused through the host machine, the effect of continuously weakening light propagation is achieved, and the problem of light leakage between the first key board 101 and the second key board 102 is avoided.
In this embodiment, the PCB 30 and the key holder 20 are locked together by screws. Specifically, the lower end surface of the key support 20 is provided with a locking column 24, the PCB 30 is provided with a locking hole 33 corresponding to the locking column 24, and the screw passes through the locking hole 33 and then is locked with the locking column 24. In order to facilitate the connection between the PCB 30 and the key holder 20, the lower end surface of the key holder 20 is provided with a positioning column 25, and the PCB 30 is provided with a positioning hole 34, and the positioning hole 34 is matched with the positioning column 25.
The intelligent switch panel also includes a mounting box 70. When the installation box 70 is used, the installation box 70 is installed on a wall, and then the bottom shell 40 is locked with the installation box 70.
Based on the structure, the embodiment is improved from two aspects, so that the light leakage prevention effect is enhanced, and the use experience of a user is improved. The method comprises the following specific steps:
one, set up protruding edge 11 or overlap joint mouth 12 in the concatenation side of keypad 10, make two keypad 10 concatenation departments form the corner structure through protruding cooperation along 11 and overlap joint mouth 12 for light passes through the diffuse reflection of host computer, reaches the effect that constantly weakens the light propagation, has avoided the problem of light leak between the keypad 10 from this. In addition, depending on the injection molding process characteristics, the larger the draft angle required for a thicker part, the larger the gap between the key sheet 10. By adopting the staggered design, the thickness of the matching part can be thinned, and the draft angle is reduced, so that the clearance between the key boards 10 is reduced, and the light leakage problem between the small key boards 10 is further avoided.
Secondly, the light guide hole 22 and the light blocking wall 221 limit the scattering space of light, so that the light is concentrated at the light transmission hole 14 as much as possible, and the scattering amount of the light is reduced. Meanwhile, the light is scattered only when reaching the key board 10 by matching with the diffusion film 13, so that the light transmission effect at the light transmission hole 14 is improved.
The above description is only an embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any slight modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments are all within the scope of the technical solution of the present invention.
