Description

Technical Field

[0001] This utility model relates to the field of mouse technology, and in particular to a three-in-one mouse IC component with metal patch. Background Technology

[0002] With the development of electronic technology, computers have become indispensable tools in our lives and work. The mouse, as a primary input device for computers, has a significant impact on our operational efficiency. The earliest mice were mechanical, which used conductive rubber wheels and negatively charged positioning axes for positioning and movement. However, mechanical mice were too inaccurate and were eventually phased out. Nowadays, the most common type is the optical mouse. Its working principle involves a light source reflecting light onto an optical sensor (sensing chip). The optical sensor (sensing chip), optical lens, and light source are essential components of an optical mouse. In the industry, these three components are generally integrated into one unit, also known as a three-in-one integrated circuit or IC component.

[0003] "While traditional three-in-one integrated ICs achieve component integration, they still employ plug-in soldering, requiring specialized fixtures for positioning. This results in a high PCB board space occupancy rate (40% larger than that of this invention). Furthermore, the lens and IC body are assembled separately, leading to optical path misalignment issues due to assembly gaps (the misalignment can reach 0.1mm), affecting mouse positioning stability. In traditional structures, the LED core and sensor chip are not physically isolated, making them susceptible to light refraction interference and prone to cursor drift. In addition, traditional IC components expose the optical lens directly, making it susceptible to burns from heat during soldering. The convex surface of the optical imaging is prone to fogging and blurring, resulting in poor IC surface performance or even malfunction. During daily use, the optical lens is also easily affected by external factors, leading to dust accumulation and aging." Utility Model Content

[0004] Purpose of the utility model: In order to overcome the shortcomings of the existing technology, this utility model provides a three-in-one metal patch mouse IC component.

[0005] Technical solution: To achieve the above objectives, the present invention provides a three-in-one metal patch mouse IC assembly, which includes an IC assembly, an IC body inside the IC assembly, an IC bottom shell below the IC body, a lens assembly inside the IC bottom shell, and an IC light shield on the lens assembly.

[0006] The IC body contains a metal sheet, on which the lamp wick and sensor chip are mounted; the entire IC assembly is mounted on the PCB board of other circuits using a surface mount method.

[0007] Furthermore, multiple IC body hardware brackets are installed on the outer side of the metal sheet, and a plastic shell is installed on the metal sheet. The IC bottom shell can be combined with the plastic shell for fixed connection.

[0008] Furthermore, the IC bottom shell has light holes; the lens assembly has an arc-shaped lens section and a convex lens section, with the arc-shaped lens section divided into surface A and surface B.

[0009] Furthermore, the IC light-shielding sheet includes a barrier sheet and a barrier plate, with the barrier plate fixedly connected to the side of the barrier sheet, and filter holes opened on the barrier sheet.

[0010] Furthermore, an IC light shield is positioned above the lens assembly, and a barrier plate is located between the lamp core and the sensing chip to separate them.

[0011] Furthermore, the position of the sensing chip corresponds to the filter hole and the convex lens; the position of the lamp wick corresponds to the curved lens.

[0012] The beneficial effects of this utility model are:

[0013] 1. Integrated design improves production efficiency: The traditionally separate IC, lens, and lamp core are integrated into one unit, and surface mount technology is used to replace plug-in soldering, reducing assembly steps, lowering processing costs, and improving production efficiency.

[0014] 2. Enhanced durability with built-in lens structure: The lens assembly is built into the IC back cover, avoiding high-temperature burns from soldering, while also preventing dust accumulation and air oxidation, thus extending its service life.

[0015] 3. Synergistic optimization of optical performance through light shielding and filtering: The barrier plate of the IC light shield isolates the light path of the lamp core and the sensor chip, preventing light refraction interference.

[0016] 4. Modular structure lowers the application threshold: Through the standardized design of IC body hardware bracket and plastic shell, it supports direct mounting on various PCB boards by SMT surface mount technology and is compatible with mainstream mouse production lines.

[0026] The present invention will be further described below with reference to the accompanying drawings. Example

[0027] like Figures 1 to 9 The three-in-one mouse IC assembly shown has an IC assembly 1000, an IC body 10 inside the IC assembly 1000, an IC bottom shell 2 installed below the IC body 10, a lens assembly 3 installed inside the IC bottom shell 2, and an IC light shield 4 installed on the lens assembly 3.

[0028] The IC body 10 contains a metal sheet 100, on which a lamp core 101 and a sensor chip 102 are mounted. Multiple IC body hardware brackets 104 are installed on the outer side of the metal sheet 100. A plastic shell 103 is mounted on the metal sheet 100. The IC bottom shell 2 can be combined with the plastic shell 103 for fixed connection. The IC assembly 1000 is mounted on the PCB board 1 in a surface mount manner.

[0029] The IC bottom shell 2 has a light hole 21; the lens assembly 3 has an arc-shaped lens part 31 and a convex lens part 32, and the arc-shaped lens part 31 is divided into surface A and surface B.

[0030] The IC light shield 4 is provided with a barrier sheet 41 and a barrier plate 42. The barrier plate 42 is fixedly connected to the side of the barrier sheet 41, and a filter hole 411 is provided on the barrier sheet 41.

[0031] The filter aperture 411 is circular, elliptical, or polygonal in shape, and its function is to filter out other stray and useless light.

[0032] The IC light shield 4 is installed above the lens assembly 3. The barrier plate 42 is located between the lamp core 101 and the sensing chip 102, separating the two and also separating the light path between the curved lens part 31 and the convex lens part 32.

[0033] The position of the sensor chip 102 corresponds to the filter hole 411 and the convex lens part 32; the position of the lamp wick 101 corresponds to the curved lens part 31.

[0034] How does the mouse IC component work?

[0035] Light path emission stage: The lamp core 101 inside the IC body 10 emits light, which shines on the curved lens part 31A surface of the lens assembly 3. After being refracted by the curved surface, the light is emitted from the B surface and projected onto the table through the light hole 21 of the IC bottom shell 2.

[0036] Light path reflection and reception stage: The light reflected from the desktop enters the convex lens section 32 of the lens assembly 3 directly through the light aperture 21. After being focused by the convex lens, it passes through the filter aperture 411 of the IC light shield 4 to filter stray light and is finally projected onto the sensor chip 102.

[0037] Signal processing stage: The sensor chip 102 generates displacement data based on the changes in the received light signal, and transmits it to the external circuit through the metal sheet 100 to realize the mouse positioning function.

[0038] In the above process, the curved lens section 31 is only responsible for refracting the light on both sides of the emitted light path AB, and the convex lens section 32 is only responsible for receiving the reflected light path. The two are physically isolated by the barrier plate 42 to avoid cross-interference of the light paths.

[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
