Description

Technical Field

[0001] The utility model belongs to the technical field of keyboard structures and relates to a luminous keyboard with a ring-edge luminous structure. Background Art

[0002] Computers have become an essential tool in people's lives, and keyboards for inputting data are also important input tools. Generally speaking, people usually operate computers in an environment with sufficient light, but in order to allow computers to be operated in a dim environment, luminous keyboards have come into being. The existing film-type luminous keyboard has a backlight device arranged under the conductive film so that the backlight device can generate light. The light generated by the backlight device will be emitted upward and reach the surface or surroundings of the keys, so that the keyboard can emit light, so that the user can clearly see the fonts on the keys.

[0003] However, the existing membrane-type luminous keyboard has a relatively simple overall luminous effect, and can only achieve the luminous effect of the key position, and the overall lighting decoration effect is monotonous; it cannot meet the current diverse market demands.

[0024] The utility model provides Figures 1 to 5 In the embodiment of the utility model, a light-emitting keyboard with a ring-shaped light-emitting structure includes: a bottom shell 6, an upper shell 2, a film circuit board 3 and a light-transmitting plate 4;

[0025] A plurality of keys 1 (including key caps and a single silicone) are arranged on the upper shell 2; during installation, the key caps are first installed into the upper shell 2, and then the silicone is placed; the thin film circuit board 3 is arranged at the lower end of the upper shell 2, and the keys 1 in the upper shell 2 are connected and matched with the thin film circuit board 3; the basic functional structure of the keyboard is realized;

[0026] The key 1 and the thin film circuit board 3 are entirely or partially light-transmitting structures;

[0027] The light-transmitting plate 4 is provided with a light-guiding fold 41 extending upward at the ring edge thereof. A light-emitting body 43 is provided at the lower end of the light-transmitting plate 4. When the light-emitting body 43 is working, the light is diffused through the light-transmitting plate 4, and the light emitted by the light-emitting body 43 can be evenly diffused, so as to achieve an effect similar to that of the entire light-transmitting plate 4 emitting light.

[0028] The upper shell 2 is inserted into the light-transmitting plate 4 from the opening of the light-transmitting plate 4 (the inner cavity is formed on the light-transmitting plate 4 by the light-guiding folded edge 41); the light-transmitting plate 4 is then inserted into the bottom shell 6 from the opening of the bottom shell 6; the light-transmitting plate 4 is connected and fixed to the upper shell 2 and the bottom shell 6 through the screw connection points 62, and the light-transmitting plate 4 is also clamped between the bottom shell 6 and the upper shell 2 to achieve the fixing work;

[0029] The upper shell 2, the light-transmitting plate 4 and the bottom shell 6 are installed in a center-aligned manner, and the length and width of the upper shell 2 are smaller than the length and width of the inner cavity on the light-transmitting plate 4, while the length and width of the light-transmitting plate 4 are smaller than the length and width of the inner cavity on the bottom shell 6. After installation, a circle of open grooves 5 will be formed between the upper shell 2 and the bottom shell 6, and the light-guiding folded edge 41 extending upward from the ring edge of the light-transmitting plate 4 is embedded in the open groove 5 formed between the upper shell 2 and the bottom shell 6. When the light-emitting body 43 is working, it can realize the light-emitting effect of the key 1 (keycap characters, keycaps, etc.) while also realizing the light-emitting effect of the ring edge of the keyboard (the position of the light-guiding folded edge 41). The overall light-emitting effect is more beautiful and more gorgeous.

[0030] The height structure of the light guide fold 41 can be designed in a manner that it is lower than the horizontal plane of the opening slot 5 or is flush with the horizontal plane of the opening slot 5;

[0031] Embodiment 1: The height of the light-guiding folded edge 41 is lower than the horizontal plane of the opening groove 5. Therefore, after assembly is completed, viewed from the front of the keyboard, the light-guiding folded edge 41 is sunken into the opening groove 5 to form a sunken structure design. In actual production, such a structure can improve the processing tolerance of the light-guiding folded edge 41 in the light-transmitting plate 4 and reduce the processing difficulty.

[0032] Embodiment 2: The height of the light-guiding folded edge 41 is flush with the horizontal plane of the opening groove 5. Therefore, after assembly is completed, viewed from the front of the keyboard, the surface of the upper shell 2 of the keyboard body, the top surface of the light-guiding folded edge 41 and the upper edge of the bottom shell 4 are all at the same level, making the overall keyboard structure more flat and beautiful.

[0033] Embodiment 3: The height of the light-guiding folded edge 41 is higher than the horizontal plane of the opening groove 5, the surface of the upper shell 2 of the keyboard body is level with the upper edge of the bottom shell 6, and the top surface of the light-guiding folded edge 41 is higher than the surface of the upper cover 2 and the upper edge of the bottom shell 6, making the light effect structure of the light-guiding folded edge 41 more prominent and more gorgeous.

[0034] In the actual production process, different processing methods can be selected according to different production needs to meet the needs of different users.

[0035] Furthermore, the inner end surface of the bottom shell 6 is formed with an annular support plate step 62. During assembly, the support plate step 62 supports the edge position of the light-transmitting plate 4, and the side end surface of the light-transmitting plate 4 is tightly fitted with the inner wall of the support plate step 62; the support plate step 62 structure is used to achieve the bottom support and all-round surrounding effect of the light-transmitting plate 4, thereby fixing and supporting the light-transmitting plate 4; the light-transmitting plate 4 can reduce the number of screw connection points 62 required between the light-transmitting plate 4 and the bottom shell 6, and without affecting the installation stability, it can not only achieve the effect of saving materials and labor time, but also make the light transmission performance of the light-transmitting plate 4 better.

[0036] It should also be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "including a ..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0037] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
