Detailed Description

The present invention will be more clearly and completely described below with reference to the accompanying drawings.

As shown in fig. 1, the present embodiment provides a key assembly, which includes a key 1, a light guide pillar 2, an indicator light 3 and a circuit board 4, wherein the key 1 and the light guide pillar 2 are made of a light guide material. The pilot lamp 3 is located circuit board 4, and leaded light post 2 one end is close to pilot lamp 3 and sets up, and the other end is connected in button 1 inboard.

In this embodiment, the indicator light 3 is a single-color LED light, but a plurality of indicator lights of the same color or different colors can be disposed on the circuit board 4, the plurality of indicator lights of the same color can obtain a more uniform light guiding effect, the plurality of indicator lights of different colors can be used in combination to indicate different signals, and the key assembly is more beautiful. If the not enough pilot lamp 3 that can't place in circuit board 4 front space, can connect the circuit after fixed pilot lamp 3 to circuit board 4 sides, adjust the position of leaded light post 2 simultaneously to guarantee the leaded light effect. The quantity of the light guide columns 2 is consistent with that of the indicating lamps 3, the positions of the light guide columns correspond to one another one by one, the centers of the light guide columns 2 and the centers of the indicating lamps 3 are located on the same straight line, and the light guide columns 2 are perpendicular to the circuit board 4 and placed, so that the light guide columns 2 have a better light guide effect.

In order to reduce mechanical damage, increase button subassembly's durability, button 1 and leaded light post 2 are integrated into one piece to adopt organic glass to make, not only guarantee like this that its mechanical properties satisfies the user demand, also can be fine compromise the leaded light performance.

In addition, the distance between the light guide column 2 and the indicator light 3 is larger than the stroke of the key 1. Since the key 1 conventionally has a bounce state and a press state, it is necessary to ensure that the light guide bar 2 does not interfere with the indicator light 3 during the pressing stroke of the key 1, otherwise the key cannot be pressed or the indicator light 3 and the light guide bar 2 are damaged.

Because the key 1 is made of light guide materials, the requirement of mobile equipment on beauty cannot be met in appearance, and the light guide performance of all parts of the surface of the whole key 1 cannot be ensured to be consistent, the surface of the key 1 is provided with the indicator light display area 5, and the area of the indicator light display area 5 is not less than 10% of the surface area of the key 1. In addition, the surface of the key 1 except the indicator light display area 5 is painted to achieve the effect of covering. Therefore, the indicator light display area 5 can be observed by a user, uneven light guide caused by too large indicator light display area 5 can be avoided, and the overall appearance of the key assembly is more attractive.

In this embodiment, after the paint coating is applied to the outer side of the key 1, the indicator display area 5 is formed by a laser etching process. The process sequence is spraying first and then laser etching, and the process is simple and feasible and easy to realize. For different products, the shape and the size of the indicator light display area 5 can be changed according to different requirements, and personalized customization of the key assembly is realized.

As shown in fig. 2, the present invention also provides a mobile device 6 including the key assembly as described above. In the mobile device 6, the key assembly is provided on a side surface of the mobile device 6 and used as a side key. In the embodiment, in order to adapt to the planarization characteristic of the overall shape of the mobile device 6, the keys 1 extend in a strip shape towards the length direction of the mobile device 6, so that the use of a user is simpler and more convenient.

If the indicator light is arranged on the front side of the mobile equipment, part of display area is occupied, and interaction is influenced; if the side surface is arranged, the number of side surface components is too large, so that the manufacturing process is complicated, and the use experience of a user is influenced. Through using foretell button subassembly, combine side key and pilot lamp, both saved the surperficial whole space of mobile device, strengthened interactive interest again.

Although specific embodiments of the present invention have been described above, it will be understood by those skilled in the art that this is by way of example only and that the scope of the invention is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and the principles of the present invention, and these changes and modifications are all within the scope of the present invention.
