Description

  The present invention relates to a light emitting keyboard, and more particularly to a light emitting keyboard having a light emitting function.

  Generally speaking, computer peripheral input devices include a mouse, keyboard and trackball, etc. Of these, keyboards can be used to input characters and symbols directly into the computer, which is of considerable importance to users and input device manufacturers. ing. Next, the structure and function of a known keyboard will be described. FIG. 1 is a schematic diagram of the external structure of a known keyboard. There are a plurality of keys on the surface of the known keyboard 1, and these keys are classified into general keys 10, numeric keys 11, function keys 12, and the like. The computer generates a signal to perform the function of the key pressed by the computer, for example, the general key 10 is used to input a code such as an alphabet, and the numeric key 11 is used to input a number. The function keys 12 are used to provide various functions, and examples thereof include F1 to F12.

  However, along with technological innovations, keyboard manufacturers have been researching and developing keyboards with various special functions and trying to satisfy the various requirements of different users. 2 is a schematic side view of the structure of a known light-emitting keyboard. The light emitting keyboard 2 includes a key 20, a metal bottom plate 21, a thin film switch circuit 22, a light source 23 and a light guide plate 24. The key 20 includes a key cap 201, a scissor-type connecting member 22, and an elastic body 203. In the light emitting keyboard 2, the above-described members are arranged in the order from top to bottom, ie, keycap 201, scissor-type connecting member 202, elastic body 203, thin film switch circuit 22, metal bottom plate 21 and light guide plate 24, The light source 23 is positioned on one side of the light guide plate 24. The light source 23 is connected to a circuit board (not shown in the drawing) of the light-emitting keyboard 2 by a flexible printed circuit (FPC) 25, and power is obtained by the flexible printed circuit 25. Here, the light source 23 is a light emitting diode (LED), and the elastic body 203 is a translucent rubber.

  In FIG. 2, the light guide plate 24 is used to guide the beam B, and the beam B is diffused throughout the keyboard, changing the traveling direction of the beam B and causing the beam B to travel upward. The thin film switch circuit 22 is provided on the metal bottom plate 21, and the metal bottom plate 21 has a first fixing structure 211, a second fixing structure 212, and two opening portions 213, and the opening portion 213 passes the beam B. The beam B is used to enter the thin film switch circuit 22. The key cap 201 includes a first key cap fixing structure 2011, a second key cap fixing structure 2012, and a translucent area 2013, and the scissor-type connecting member 202 includes a first frame 2021 and a second frame 2022. The first end 2021A of the first frame 2021 is connected to the second fixing structure 212, the second end 2021B of the first frame 2021 is connected to the first keycap fixing structure 2011, and the first end 2022A of the second frame 2022 is The second end 2022 </ b> B of the second frame 2022 is connected to the second keycap fixing structure 2012.

  Subsequently, when the key 2 in FIG. 2 is pressed and moves downward with respect to the metal bottom plate 21, the first frame 2021 and the second frame 2022 of the scissor-type connecting member 202 change from the open / closed state to the folded state, In addition, the key cap 201 that moves downward compresses and contracts the elastic body 203 so that the elastic body 203 contacts the thin film switch circuit 22 and generates a key signal corresponding to the key 20. When the key 20 is no longer pressed, the elastic body 203 provides an elastic force to the key cap 201, the key cap 201 moves upward with respect to the metal bottom plate 21, and the first frame 2021 and the second frame 2022 are It changes from the folded state to the open / closed state, and the key cap is returned to the original position. When the light source 23 generates the beam B, the beam B enters the light guide plate 24, the light guide plate 24 changes the direction of the beam B, a part of the beam B is blocked by the metal bottom plate 21, and the remaining beams are opened. Passes through the part 213 and enters the thin film switch circuit 22. Subsequently, the beam B sequentially passes through the thin film switch circuit 22, the elastic body 203, and the translucent area 2013 on the key cap 201, and causes the key 20 to emit light. However, when the known light-emitting keyboard is operated, most of the beams B generated by the light source 23 positioned below the metal bottom plate 21 are blocked by the metal plate 21, so that the light-emitting keyboard of the known light-emitting keyboard is not uniform.

Next, a third embodiment of the light emitting keyboard of the present invention will be described.
FIG. 5 is a schematic side view of a local structure according to a more preferred embodiment of the light-emitting keyboard of the present invention. In the light-emitting keyboard 3, the translucent intermediate frame 31 is provided on the support plate 30, and the structural strength of the translucent intermediate frame 31 is enhanced by the support plate 30, so that it is avoided that the translucent intermediate frame 31 is bent. it can. The light guide film 36 is provided between the translucent intermediate frame 31 and the support plate 30. The light source thin film 35 is provided below the support plate 30. The light source 33 is provided on the light source thin film 35. The beam B ′ generated by the light source enters the light guide film 36 by extending to the support plate opening 301 and the light guide film opening 361.

  The thin film switch circuit 34 is provided on the translucent intermediate frame 31, the upper circuit board 341 is folded on the partition layer 342, and the partition layer 342 is folded on the lower circuit board 343. The elastic body 323 is provided on the thin film switch circuit 34, and the key cap 321 is provided on the elastic body 323. The scissor-type connecting member 322 is positioned between the translucent intermediate frame 31 and the key cap 321, and connects the translucent intermediate frame 31 and the key cap 321 so that the key cap 321 moves up and down with respect to the translucent intermediate frame 31. Here, the first end 3221A of the first frame 3221 of the scissor-type connecting member 322 is connected to the second intermediate frame fixing structure 312 and the second end 3221B of the first frame 3221 is the first key. The first end 3222A of the second frame 3222 of the scissor-type connecting member 322 is connected to the second keycap fixing structure 313, and the second end 3222B of the second frame 3222 is connected to the first intermediate member. The frame fixing structure 311 is connected.

  When the key 32 is pressed and moves downward with respect to the translucent intermediate frame 31, the first frame 3221 and the second frame 3222 of the scissor-type connecting member 322 change from the open / closed state to the folded state and move downward. The key cap 321 that presses and contracts the elastic body 323 causes the elastic body 323 to come into contact with the thin film switch circuit 34. In the thin film switch circuit 34, the upper connection point 3411 extends into the partition layer opening 3421, contacts the lower connection point 3431, and electrical conduction between the upper connection point 3411 and the lower connection point 3431 is established. A key signal corresponding to the key 32 is generated. When the key 32 is not pressed, the elastic body 323 provides an elastic force to the key cap 321, the key cap 321 moves upward with respect to the translucent intermediate frame 31, and the first frame 3221 and the second frame 3222 changes from the folded state to the open / closed state, and the keycap 321 is returned to its original position.

  According to FIG. 5, when the light source 33 generates the beam B ′, a part of the beam B ′ is projected and enters the light guide film 36, and a part of the beam B ′ is changed in its traveling direction and sequentially transmitted. The light passes through the optical intermediate frame 31 and the thin film switch circuit 34 and is projected onto the key 32. Here, a part of these beams B ′ passes through the elastic body 323 and is projected onto the key cap 321 and the other part of the beam. B ′ does not pass through the elastic body 323 but is projected onto the key 321. On the other hand, another part of the beam B ′ is projected downward and reflected by the support plate 30 to change its traveling direction, and another part of the beam B ′ enters the light guide film 36, and the keycap is passed through the above-described path. 321 is projected. Finally, the beam B ′ passes through a light-transmitting area 3211 positioned on the keycap 321, thereby causing the light-emitting keyboard 3 to emit light.

  Incidentally, the translucent area 3211 on the keycap 321 is an area having characters and symbols on the surface of the keycap 321, for example, an area having the letter A on the key A. With the above-described structure, when the beam B ′ passes through the light-transmitting region 3211, characters and symbols on the key 32 are caused to emit light.

  As can be seen from the above, the translucent intermediate frame of the light-emitting keyboard of the present invention has the same function as a well-known metal bottom plate--joins with a scissor-type connecting member, establishes the connection between the key and the translucent intermediate frame, and transmits light. The intermediate frame is made of a transparent material, the light source can be provided below the translucent intermediate frame, and the beam passes through the translucent intermediate frame and is not blocked, so that the beam passing through the keycap has higher brightness. There is no phenomenon that the beam is blocked by a well-known metal bottom plate and non-uniformity of light irradiation occurs. That is, since the translucent intermediate frame manufactured by the transparent material can pass the beam, the position where the light source can be installed is not limited as in the known light emitting keyboard. Further, the support plate is provided with a support plate aperture corresponding to the light source, the light source can extend into the support plate aperture, and the beam generated by the light source is blocked by the support plate. Therefore, the light source can be provided at a position below the support plate.
