Abstract
Description
Technical Field
[0001] This utility model relates to the field of computer equipment, and in particular to a touchpad module. Background Technology
[0002] Most laptop or leather case keyboard touchpads on the market currently lack LED status indicators. Even if they do, they only provide simple static on / off status indications. Furthermore, the indicator lights are usually placed directly around the touchpad, which not only hinders finger movement during touchpad use, especially given the limited space on the laptop's keyboard, but also results in an overly simplistic display that fails to meet users' needs for multifunctional, dynamic, and aesthetically pleasing interaction, while remaining conspicuously positioned. Utility Model Content
[0003] The main technical problem solved by this utility model is to provide a touchpad module with a hidden dynamic status indication function, which can provide a variety of light indication combinations as needed when in use, and can hide the light structure when not in use.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a touchpad module with a hidden dynamic status indication function is provided. The touchpad module includes a touchpad panel, a PCB board and a metal support frame stacked from top to bottom. The touchpad panel is a glass panel. A status indication area is set on the edge of the glass panel. An LED light strip is arranged below the status indication area. The LED light strip is composed of multiple LEDs. Each LED light strip is connected to the lighting control system through an independent FPC board. A semi-transparent paint layer and a light-shielding paint layer are sprayed sequentially on the back of the status indication area. A light-transmitting window is opened on the light-shielding paint layer directly above each LED.
[0005] In a preferred embodiment of this utility model, a character is provided in the middle of the light-transmitting window, and the character is located between the semi-transparent paint layer and the glass panel.
[0006] In a preferred embodiment of the present invention, the status indicator area is arranged along one or more edges of the glass panel, and the LEDs on the LED light strip below the status indicator area are arranged in an array or in series.
[0007] In a preferred embodiment of this utility model, the LED light strip is arranged on a corresponding FPC board, and the FPC board is arranged on the outside of the PCB board by means of the metal support frame and does not exceed the projection range of the glass panel.
[0008] In a preferred embodiment of this utility model, both the light-blocking paint and the semi-transparent paint are dark-colored paints and belong to the same color family.
[0009] The beneficial effects of this utility model are as follows: This utility model is based on the structural optimization of existing touchpad modules, enabling the touchpad module to dynamically light up the light-transmitting windows of the surrounding LEDs according to instructions during use. When not in use, the lighting mechanism can be automatically hidden under the panel. In this way, when the touchpad is in use, it can not only provide a rich combination of lights to display the usage status of the touchpad or other application devices according to system instructions, but also significantly improve the visual effect of the entire keyboard when in use. Moreover, when not in use, the lighting structure is completely hidden, making it indistinguishable from an ordinary keyboard, with a significant contrast effect, thereby enhancing the product's appeal to the younger generation. Attached Figure Description
[0010] Figure 1 This is a top view of a preferred embodiment of the present invention; Figure 2 This is a schematic diagram of the material stacking in the illustrated embodiment; Figure 3 This is a schematic diagram of the lighting control logic in the illustrated embodiment; The components in the attached diagram are labeled as follows: 1. Glass panel, 101. Status indicator area, 102. Light-transmitting window, 2. PCB board, 3. Metal support frame, 4. FPC board, 5. LED light strip. Detailed Implementation
[0011] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.
[0012] Please see Figures 1 to 3 The embodiments of this utility model include: A touchpad module with a hidden dynamic status indication function includes a touchpad panel, a PCB board 2, and a metal support frame 3 stacked from top to bottom. The touchpad panel is a glass panel 1, and multiple status indication areas 101 can be set on the edge of the glass panel 1. In actual implementation, two status indication areas 101 are generally symmetrically arranged along the two edges. Each status indication area 101 is equipped with an LED light strip 5 arranged in series below it. Each LED light strip 5 is composed of multiple LEDs. Each LED light strip 5 is connected to the lighting control system through an independent FPC board 4. In this way, multiple LEDs can be combined to create a variety of different lighting modes. Each lighting mode can represent a status command, significantly improving the corresponding status indication range. The back of the status indication area 101 is coated with a semi-transparent paint layer and a light-shielding paint layer in sequence. A light-transmitting window 102 is opened on the light-shielding paint layer directly above each LED.
[0013] The light-transmitting window 102 has a character pattern in the middle, which is located between the semi-transparent paint layer and the glass panel 1. By setting the character pattern, the overall working status of the touchpad module can be displayed intuitively, and the character pattern sandwiched between the semi-transparent paint layer and the glass panel 1 can prevent the character pattern from fading due to long-term repeated friction between the finger and the character pattern.
[0014] The LED light strip 5 is mounted on the corresponding FPC board 4. The FPC board 4 is mounted on both sides of the PCB board 2 with the support of the metal support frame 3 and does not exceed the projection range of the glass panel 1. In this way, the entire module structure is compact, and the FPC board 4 and LED light strip 5 can be protected by the upper glass panel 1 and the lower metal support frame 3, making them less prone to damage during assembly.
[0015] Both the light-blocking paint and the semi-transparent paint are dark-colored and belong to the same color family. Dark colors have a better concealing effect than light colors. In actual implementation, the light-blocking paint and the semi-transparent paint are generally black or gray, so that when the LED light is not lit, the light-transmitting window structure reserved on the back of the glass panel 1 cannot be detected by the human eye.
[0016] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
