A physical key assembly suitable for a touch screen

Abstract

This utility model discloses a physical button assembly suitable for touch screens, belonging to the technical field of electronic device accessories. It includes a predetermined number of button assemblies housed within a casing. Each button assembly comprises a button body, an elastic reset component, and a conductive film. The key feature is that wires electrically connect the conductive films of the predetermined number of button assemblies. When the button body and the elastic reset component move downwards under force, the conductive films contact the screen and form a capacitive coupling effect. The beneficial effect of this utility model is that by electrically connecting multiple conductive films with wires to form a capacitive coupling array, the capacitive coupling effect achieves signal transmission by changing the electric field distribution on the touch screen surface. This eliminates the problem of existing key buttons having top and bottom conductive connections, requiring sufficient coupling charge from the human body, resulting in poor button tactile feedback, especially when wearing gloves in winter.

Description

Technical Field

[0001] This utility model belongs to the technical field of electronic device accessories, and more specifically relates to a physical button component suitable for touch screens. Background Technology

[0002] With the development of technology, mobile phones have become increasingly powerful and diverse, permeating all aspects of people's daily lives. Among these, mobile games, which rely on mobile phones, have become an important part of people's entertainment due to their strong entertainment value. However, touchscreen controls have limitations, and current mobile game control solutions mainly face the following technical bottlenecks:

[0003] 1. Defects in touchscreen operation experience

[0004] Capacitive touchscreen devices rely on direct finger touch operation. When playing games that require high-frequency and precise input, such as fighting or action games, the limited touch area can easily lead to misoperations. Especially for emulator games that require multi-button interaction, the lack of physical feedback from virtual buttons severely affects operational accuracy and immersion.

[0005] 2. Insufficient compatibility with external devices

[0006] Existing improvement solutions focus on two types of peripherals:

[0007] Bluetooth gamepads have issues such as high connection latency (usually >50ms), inconvenience in carrying, and the detachable design from the phone disrupts the seamless operation.

[0008] When a traditional game controller is applied directly to a capacitive screen, the conductive film cannot form a capacitive coupling effect when it comes into contact with the screen as the buttons and elastic reset components move downwards under force.

[0009] National utility model patent number 202120665870.6 discloses a game controller for Tencent that effectively solves the above problems, enabling a game controller to directly operate on a capacitive screen.

[0010] The game controller includes a controller body, a capacitive touch screen, and a button module; the skill button extends through the thickness of the module body, and the top and bottom of the skill button are electrically connected. The skill button is configured so that its bottom contacts the capacitive touch screen when pressed.

[0011] This device utilizes the conductive connection between the top and bottom of the skill buttons. Therefore, the skill buttons can either be made of a conductive material, which differs from the tactile feel of traditional game controllers' plastic material, or conductive contacts can be placed on the plastic buttons, indirectly allowing the human body to contact the capacitive touchscreen and create a capacitive coupling effect. This alters the electric field distribution on the touchscreen surface, enabling signal transmission. However, this approach can create a foreign object sensation during use, affecting the gaming experience. Utility Model Content

[0012] To solve the above problems and overcome the shortcomings of the prior art, this utility model provides a physical button component suitable for touch screens;

[0013] The first technical problem to be solved was that when a traditional game controller is applied directly to a capacitive screen, the conductive film cannot form a capacitive coupling effect when it comes into contact with the screen as the button body and the elastic reset component move downward under force.

[0014] The second technical problem to be solved is that the game controller consists of a main body, a capacitive touch screen, and a button module; the skill button runs through the thickness of the module body, and the top and bottom of the skill button are electrically connected, which will cause a foreign object feeling when using it and affect the gaming experience.

[0015] The specific technical solution of this utility model to solve the above-mentioned technical problems is as follows: the physical button assembly suitable for touch screens includes a preset number of button assemblies disposed in a housing. Each button assembly includes a button body, an elastic reset member, and a conductive film. The elastic reset member is used to reset the button body. The invention is characterized by:

[0016] A set number of conductive films of the key assembly are provided with wires that electrically connect the conductive films of the key assembly. When the key body and the elastic reset member are subjected to force and move downward, the conductive film contacts the screen and forms a capacitive coupling effect.

[0017] Furthermore, the conductive film is a carbon film or a metal conductive film.

[0018] Furthermore, the metal conductive film is a copper film, a silver film, or an aluminum film.

[0019] Furthermore, a conductive adhesive tape is provided below the conductive film to increase the charge adsorption and buffering effect of the screen.

[0020] Furthermore, one end of the wire is electrically connected to the conductive film, and the other end of the wire is electrically connected to the phone case through a housing compression.

[0021] Furthermore, one end of the wire is electrically connected to the conductive film, and the other end of the wire is electrically connected to the conductor.

[0022] Furthermore, the conductor is any one of aluminum foil, copper foil, silver foil, or gold foil.

[0023] Furthermore, the conductor is fixed inside the housing.

[0024] The beneficial effects of this utility model are:

[0025] One advantage of this invention is that multiple conductive films are electrically connected by wires to form a capacitive coupling array. The capacitive coupling effect achieves signal transmission by changing the electric field distribution on the surface of the touch screen. This eliminates the problem of the existing technology where the top and bottom of the skill keys are conductively connected, requiring the human body to obtain sufficient coupling induction charge, which leads to poor key feel, especially when wearing gloves in winter.

[0026] One advantage of this invention is that one end of the wire is electrically connected to the conductive film, and the other end of the wire is electrically connected to the conductor, which further increases the coupling induced charge, improves the capacitive coupling effect, and realizes signal transmission by changing the electric field distribution on the touch screen surface, thereby improving the sensitivity of the device.

[0027] One advantage of this invention is that a conductive adhesive tape is provided under the conductive film to increase the charge adsorption and buffering effect of the screen. Attached Figure Description

In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0035] Specific embodiments of this utility model:

[0036] Example 1:

[0037] A physical button assembly for a touchscreen includes a predetermined number of button assemblies disposed within a housing 1. Each button assembly includes a button body 2, an elastic reset member 3, and a conductive film 4. The elastic reset member 3 is used to reset the button body 2.

[0038] The improvement of this utility model is as follows:

[0039] A wire 5 is provided between the conductive films 4 of a preset number of button assemblies to electrically connect the conductive films 4 of the preset number of button assemblies. When the button body 2 and the elastic reset member 3 are subjected to force and move downward, the conductive film 4 contacts the screen and forms a capacitive coupling effect.

[0040] As a preferred embodiment of this utility model, the conductive film 4 is a carbon film or a metal conductive film.

[0041] More preferably, the metal conductive film is a copper film, a silver film, or an aluminum film.

[0042] Example 2 is the same as Example 1, except that: a conductive adhesive tape 6 is also provided below the conductive film 4 to increase the charge adsorption and buffering effect of the screen.

[0043] Example 3 is the same as Example 1 or Example 2, except that one end of the wire 5 is electrically connected to the conductive film 4, and the other end of the wire 5 is electrically connected to the mobile phone case by being squeezed by the housing 1.

[0044] This utility model can also be configured such that one end of the wire 5 is electrically connected to the conductive film 4, and the other end of the wire 5 is electrically connected to the conductor 7.

[0045] Specifically, the conductor 7 is any one of aluminum foil, copper foil, silver foil, or gold foil.

[0046] Furthermore, the conductor 7 can also be fixed inside the housing 1.

[0047] It should be noted that this utility model is a physical button component suitable for touch screens. In actual operation,

[0048] 1. Secure the housing 1 to the phone's outer shell, with a preset number of button assemblies corresponding to the virtual buttons on the phone screen;

[0049] Because the conductive films 4 of the preset number of button assemblies are connected by wires 5, when the conductive film 4 moves downward under the force of the button body 2 and the elastic reset member 3, pressing a virtual button corresponds to an area, making contact with the screen and forming a capacitive coupling effect.

[0050] By electrically connecting multiple conductive films with wires to form a capacitive coupling array, the capacitive coupling effect achieves signal transmission by changing the electric field distribution on the surface of the touch screen. This eliminates the problem of the existing technology where the top and bottom of the skill keys are conductively connected, requiring the human body to obtain sufficient coupling induction charge, resulting in poor button tactile feedback, especially when wearing gloves in winter.

[0051] 2. One end of the wire 5 is electrically connected to the conductive film 4, and the other end of the wire 5 is electrically connected to the conductor 7, forming a stronger capacitive coupling array, which further increases the coupled induced charge and improves the capacitive coupling effect. By changing the electric field distribution on the touch screen surface, signal transmission is achieved, thereby improving the sensitivity of the device.

[0052] 3. A conductive adhesive tape 6 is also provided below the conductive film 4 to increase the charge adsorption and buffering effect of the screen.

[0053] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
