Description

mark structure

This disclosure relates to an identification structure, particularly an identification structure provided in a computer peripheral device.

Among various computer peripheral devices, such as keyboard, it is an indispensable input device for operating a computer. Through the keyboard, text, symbols, special actions, etc. can be input to the computer host to effectively control the computer. However, most of the keyboards used in general personal computers, network workstation computers, etc. have a fixed appearance model and rarely change. Although the main function of the keyboard is only to input command signals, nowadays, in terms of personalized and humanized work, In this environment, the traditional cold and dull keyboard mechanism obviously does not meet the above needs, and as far as manufacturers are concerned, it is difficult to increase the added value of a keyboard with poor quality.

In view of the above problems, there are currently technologies that provide luminous marking structures on the surface of computer peripherals (for example, computer keyboards), thereby changing the appearance and texture of the computer keyboard, or providing marking functions that are legible to the human eye. A typical sign structure generally forms an opening on the surface of a computer peripheral device (for example, a computer keyboard), places a light-emitting unit in the opening, and then uses a light guide column or diffusion plate to guide the light to the opening and then emit it outward.

However, before the light is emitted from the opening, it usually needs a certain distance to be mixed or fogged, so that the emitted light can produce the desired visual effect. The additional light mixing distance may not be able to take into account the thinning requirements of computer peripherals. Therefore, there is a need to provide an advanced marking structure to improve the problems faced by the conventional technology.

An embodiment of this specification discloses a sign structure provided on an electronic device, including a cover plate, a light-emitting element, a light-transmitting component and a supporting component. The cover has a light-emitting area. The light-emitting element is located under the cover and corresponds to the light-emitting area. The light-transmitting component is located between the cover plate and the light-emitting element and corresponds to the light-emitting area. The support member is located between the cover plate and the light-emitting element, and has a recessed portion and a through hole. The recessed portion is used to accommodate the light-transmitting component, so that there is a distance between the light-transmitting component and the light-emitting element. The through hole passes through the bottom of the recess and is aligned with the light emitting element.

Another embodiment of this specification discloses a sign structure provided on an electronic device, including a light guide plate, a light-emitting element, a nameplate and an acrylic double-sided tape. The light guide plate has a light exit surface, a back surface and at least one side surface. Wherein, the back side of the light guide plate is relative to the light exit surface; the side surface of the light guide plate is connected to the light exit surface; and the light emitting element is adjacent to the side surface of the light guide plate. The nameplate is located above the light-emitting surface and includes a light-transmitting area and an opaque area for the logo. Acrylic double-sided tape is attached to the back of the light guide plate and overlaps the light-transmitting area of the logo. Among them, the contact area between the acrylic double-sided tape and the back surface of the light guide plate is substantially greater than or equal to the area of the light-transmitting area of the mark, and smaller than the back surface area of the light guide plate.

Another embodiment of this specification discloses a sign structure provided on an electronic device, including a cover plate, a light-emitting element and a reflective member. The cover plate has a light-transmitting area and a light-impermeable area. The light-emitting element is located under the inner surface of the cover and overlaps with the opaque area. The reflective member is located under the inner surface of the cover plate and has a plurality of reflective surfaces, at least a part of which overlaps the light-transmitting area and is adjacent to the light-emitting element. Among the plurality of reflective surfaces, at least one central distance closest to the center of the light-transmitting area is smaller than a plurality of peripheral distances between the other reflective surfaces and the inner surface.

Based on the above, embodiments of the present specification provide a marking structure provided on an electronic device, through a simple support structure, uniform light structure or reflective structure, so as to increase the number of light-emitting elements without significantly increasing the thickness of the electronic device. The light mixing or fogging distance of the emitted light is used to produce the desired visual effect on the light emitted from the marking structure, while taking into account the need for thinner electronic devices.
