Description

Technical Field

[0001] This utility model relates to the field of consumer electronics technology, specifically to a positioning plate integration with light effects and its keyboard. Background Technology

[0002] With the development of consumer electronics and keyboards, users have more immersive operation needs, one of which is the rich color display surface of the keyboard facing the user. The existing keyboard displays the user-facing display by means of an LED light matrix installed near the keys.

[0003] The core hardware structure of current magnetic axis keyboards can be divided into three layers: the top layer is the positioning plate that fixes the magnetic axis keys, also known as the middle plate in the industry; the PCB board integrates various control circuits and Hall sensor matrices; and the bottom layer is the base. Current LED lights are located near the Hall sensors on the PCB board. Light shines through perforations in the middle plate onto the keycaps, creating the lighting effect.

[0004] However, the existing technology has the problem that the angle of light illumination is limited by the perforation. Utility Model Content

[0005] The purpose of this invention is to provide a positioning plate integration with light effect. By integrating the LED light group on the substrate, it differs from the existing technology of setting the LED light on the PCB board and solves the problem of the illumination angle being limited by the perforation in traditional magnetic axis keyboards.

[0006] This utility model provides an integrated positioning plate with light effect, including a substrate, and mounting holes for supporting magnetic shaft buttons on the substrate, and an LED light group disposed on the substrate, the LED light group being located near the mounting holes and on the side of the substrate facing the user; and a wiring layer disposed thereon, the wiring layer being used for signal transmission and power supply of the LED light group.

[0007] Preferably, the wiring layer is a metal line etched on the substrate or a flexible printed circuit board.

[0008] Preferably, the LED light group is positioned above the upper surface of the substrate and the sidewall of the mounting hole.

[0009] Preferably, a groove is formed on the side of the substrate facing the magnetic axis keycap, and the LED light group is located in the groove.

[0010] Preferably, a ceramic plate is embedded in the substrate, and the ceramic plate is located directly below the LED light assembly.

[0011] Preferably, the ceramic plate is covered with a reflective coating.

[0012] Preferably, a light diffusion layer is covered on the LED light assembly.

[0013] Preferably, pins are provided on the substrate, and the pins are connected to the wiring layer lines.

[0014] This utility model also provides a keyboard, which integrates any of the above-described positioning plates with light effects.

[0015] Compared with the prior art, the beneficial effect of this utility model is that by reconstructing the LED light group onto the positioning plate, it breaks through the optical limitation of the traditional magnetic boat keyboard LED light group being perforated on the positioning plate, and realizes wide-angle lighting.

[0016] On the other hand, by moving the LED light assembly from the PCB board to the positioning board, the space available for sensor density on the PCB board can be freed up.

[0017] Furthermore, by placing the LED light group on the substrate and near the mounting holes of the magnetic axis keys, the light emitted by the LED light group is not limited by the matching of the keycap style. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1 to 3 This utility model provides a positioning plate integration 100 with light effect, including a substrate 10, and a mounting hole 11 for supporting a magnetic shaft button on the substrate 10. It also includes an LED light group 13 disposed on the substrate 10, the LED light group 13 being located near the mounting hole 11 and on the side of the substrate 10 facing the user; and a wiring layer 20 disposed thereon, the wiring layer 20 being used for signal transmission and power supply of the LED light group 13.

[0027] In implementation, the substrate 10 is made of glass fiber reinforced epoxy resin with a thickness ranging from 1.5mm to 3mm, and rectangular mounting holes 11 are formed on it to support the magnetic shaft buttons. At least one LED is symmetrically arranged around each mounting hole 11, located on the upper surface of the substrate 10 and at a distance from the edge of the mounting hole 11, as long as it does not interfere with the position of the button shell. The wiring layer 20 forms a 0.2mm thick copper wiring layer on the surface of the substrate 10 through an etching process. The power supply line width is 0.3mm and it is connected to the power pin on the USB of the keyboard 200. The signal control line is used for signal transmission and has a line width of 0.1mm.

[0028] In this way, by reconstructing the LED light group 13 onto the positioning plate, the optical limitation of the traditional magnetic boat keyboard 200 LED light group 13 being perforated on the positioning plate is overcome, and wide-angle lighting is achieved.

[0029] On the other hand, by moving the LED light group 13 from the PCB board to the positioning board, the space for sensor density on the PCB board can be freed up.

[0030] Furthermore, the LED light group 13 is placed on the substrate 10 and near the mounting hole 11 of the magnetic axis key, so that the light emitted by the LED light group 13 is not limited by the matching of the keycap style.

[0031] Furthermore, the wiring layer 20 is a metal line etched on the substrate 10 or a flexible printed circuit board.

[0032] When a thinner overall thickness of the keyboard 200 is required and a higher cost is acceptable, a trace layer 20 with metal lines etched on the substrate 10 is used. When the thickness requirement of the keyboard 200 is not high and a lower cost is required, a flexible printed circuit board is used for mounting.

[0033] Furthermore, the LED light group 13 is positioned higher than the upper surface of the substrate 10 and the sidewall of the mounting hole 11.

[0034] In this way, the light angle is not blocked by the upper surface of the substrate 10 at all.

[0035] Furthermore, a groove 12 is provided on the side of the substrate 10 facing the magnetic axis keycap, and the LED light group 13 is located in the groove 12.

[0036] During implementation, the LED group is embedded in the groove 12, which improves the overall aesthetics and completely avoids physical conflicts with buttons and keycaps of various styles and sizes.

[0037] Furthermore, a ceramic plate 30 is embedded in the substrate 10, and the ceramic plate 30 is located directly below the LED light group 13.

[0038] In this way, the heat generated by the LED light group 13 during operation can be dissipated in a timely manner through the ceramic plate 30 in the dense space between the substrate 10 and the button.

[0039] Furthermore, a reflective coating 40 is applied to the ceramic plate 30.

[0040] In practice, a compound composition of nano-barium sulfate and fumed silica is used. The ceramic plate 30 is covered on the side facing the LED lamp group 13 through a continuous process of plasma treatment, electrostatic spraying, and then UV curing, thereby increasing the illuminance value of the LED lamp group 13.

[0041] Furthermore, a light diffusion layer is applied to the LED light group 13.

[0042] During implementation, a light-guiding silicone film is used to cover the LED light group 13, and the light diffuses omnidirectionally within the light diffusion layer to achieve wide-angle diffused light.

[0043] For further details, please refer to Figure 4 A pin 60 is provided on the substrate 10, and the pin 60 is connected to the wiring layer 20.

[0044] In this way, a detachable connection can be formed between the pin 60 and the needle tube on the PCB board. During operation, the connection can be pressed to achieve signal transmission, and it can be quickly disassembled for easy maintenance.

[0045] like Figure 5 As shown, this utility model also provides a keyboard 200, which is equipped with any of the above-described positioning plate integration 100 with light effect.

[0046] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and are all included within the protection scope of this application.
