[0039] Refer to Figures 1 to 3 , according to the first aspect embodiment of the present invention, the light-emitting button assembly includes: a positioning plate 10, a button shaft 20, a sensing element 30, and a light-emitting element 40. A plurality of positioning holes 11 are provided on the positioning plate 10, and the positioning holes 11 are used to accommodate buttons; the button shaft 20 is disposed on the positioning plate 10 and located in the positioning holes 11; the sensing element 30 is disposed above the positioning plate 10. The sensing element 30 includes a plurality of sensing areas 31, and the sensing areas 31 can cover a plurality of positioning holes 11. The sensing element 30 can be used to sense the position of an object in the air; the light-emitting element 40 is disposed below the positioning plate 10. The light-emitting element 40 has a plurality of light sources. The sensing element 30 is electrically connected to the light-emitting element 40. The sensing areas 31 can cover a plurality of light sources. The sensing element 30 can wake up the light sources, and the light sources can transmit through the button shaft 20 and emit light to the outside.

[0040] Specifically, the embodiments of the present utility model relate to an innovative luminous key component, which is particularly suitable for electronic devices that require visual feedback and enhanced user experience, such as gaming keyboards, music controllers, etc. The following is a detailed description of the specific implementation of the luminous key component according to the embodiments of the present utility model.

[0041] The positioning plate 10 serves as the basic structure of the luminous key component. It is provided with a plurality of positioning holes 11, which are used to accurately accommodate and fix the key shafts 20, ensuring that the keys are stable and responsive during operation. The positioning plate 10 can be made of hard plastic, metal or composite materials to ensure its strength and durability. The key shafts 20 are installed in the positioning holes 11 of the positioning plate 10. Each key shaft 20 corresponds to a key, allowing the key to move freely in the vertical direction. The design of the key shafts 20 needs to ensure that the keys can move smoothly when pressed and released, while maintaining a good feel. The material of the key shafts 20 can be selected from wear-resistant and low-friction coefficient materials, such as POM (polyoxymethylene) or nylon, to extend the service life. The sensing element 30 is cleverly arranged above the positioning plate 10 and includes a plurality of sensing areas 31. Each sensing area 31 can cover a plurality of positioning holes 11. This means that the user does not need to directly touch the key, and the sensing element 30 can trigger the corresponding function by sensing the position of an object in the air (such as a finger approaching). The sensing element 30 can adopt capacitive, infrared or electromagnetic induction technology to achieve high-precision non-contact sensing. The lighting element 40 is arranged below the positioning plate 10 and includes a plurality of independent light sources, such as LED lights. Each light source corresponds to at least one position below the key shaft 20, ensuring that the light can evenly and effectively pass through the key shaft 20 and emit a charming lighting effect to the outside. The lighting element 40 is electrically connected to the sensing element 30. When the sensing element 30 detects the position of an object in the air, it can immediately wake up the corresponding light source to achieve instant visual feedback.

[0042] In practical applications, when the user's finger approaches or hovers above the key, the sensing element 30 immediately recognizes this action and activates the corresponding light source. The light source then lights up and emits light through the transparent or translucent part of the key shaft 20, providing an intuitive visual cue for the user. This process not only enhances the user's operation experience but also gives the product a unique visual effect. In summary, the luminous key component according to the embodiments of the present utility model combines the ingenious designs of the positioning plate 10, the key shafts 20, the sensing element 30 and the lighting element 40 to achieve non-contact sensing control and dynamic lighting effects, greatly enhancing the interactivity and aesthetics of the user interface.

[0043] Therefore, it can be understood that the light-emitting button assembly according to the embodiments of the present utility model has at least the following beneficial effects: Through the sensing element 30 on the positioning plate 10, the position of an object approaching the button shaft 20 can be sensed, thereby waking up the light source of the light-emitting element 40 at the corresponding position, and then causing the light source at the corresponding position to emit light; and the emitted light can be emitted to the outside through the button shaft 20, ultimately achieving the purpose of emitting light according to the position of the object in a dim environment, facilitating the use of the user.

[0044] It should also be noted that the light-emitting element 40 and the sensing element 30 are respectively arranged below and above the positioning plate 10, so that the light-emitting element 40 and the sensing element 30 can be separated, thereby avoiding the interference of the circuit structure in the light-emitting element 40 on the sensing effect in the sensing element 30, and further ensuring the stable sensing of the sensing element 30.

[0045] Refer to Figures 2 to 4 , further, in some embodiments of the present utility model, the sensing element 30 includes a flexible printed circuit board 32, the flexible printed circuit board 32 has a plurality of induction coils 321, the induction coils 321 are wound in the flexible printed circuit board 32, and the induction coils 321 have an induction area 31.

[0046] This embodiment further elaborates in detail the specific structure and configuration of the sensing element 30. The sensing element 30 is a key part in the light-emitting button assembly of the present utility model, and it is responsible for non-contact sensing control. In this embodiment, the sensing element 30 particularly uses a flexible printed circuit board 32 as the base. The flexible printed circuit board 32 not only has good flexibility and bendability, but also is convenient for wiring and connection inside the assembly.

[0047] A plurality of induction coils 321 are arranged on the flexible circuit board 32, and these induction coils 321 are cleverly wound in the flexible circuit board 32. Each induction coil 321 forms an independent induction area 31, which can cover a plurality of positioning holes 11, thereby realizing accurate sensing of the position of the object in the air. Specifically, the induction coil 321 is wound beside the positioning hole 11, and the positioning holes 11 on both sides of the induction coil 321 can fall into the sensing range of the induction coil 321. When the user's finger or other object approaches the key, the induction coil 321 will immediately detect this change and trigger the corresponding function. The working principle of the induction coil 321 is based on the principle of capacitive sensing. Capacitive sensors are non-contact detection devices. When an object in the air (such as a finger) approaches the induction coil 321, the electric field effect is used to detect nearby objects, and they are particularly good at detecting conductive materials. Their working principle is similar to that of a capacitor. When the target object approaches the sensor, the capacitance will change, affecting the oscillator circuit, thereby detecting the object. Using the induction coil 321 as the induction area 31 has multiple advantages. First, it can achieve high-precision non-contact sensing, improving the user's operating experience. Second, the structure of the induction coil 321 is relatively simple, and the manufacturing cost is low, which is conducive to the wide application of the product. Finally, due to the flexibility of the flexible circuit board 32, the induction coil 321 can be more flexibly arranged inside the component, adapting to the design of buttons of different shapes and sizes.

[0048] Reference Figures 2 to 3 as well as Figure 5 In some embodiments of the present invention, the light emitting element 40 includes a rigid circuit board 41, on which a light source circuit is disposed, and the light source circuit is electrically connected to the light source.

[0049] This embodiment will further elaborate on the specific structure and configuration of the light-emitting element 40. The light-emitting element 40 is a key part in the light-emitting button assembly of the present utility model responsible for generating the light effect. In this embodiment, the light-emitting element 40 particularly uses a rigid circuit board 41 as the substrate. The rigid circuit board 41 has good stability and load-bearing capacity, which can ensure the stability and durability of the light-emitting element 40 during long-term use. A light source circuit is provided on the rigid circuit board 41, which is the core part of the light-emitting element 40. The light source circuit is responsible for providing a stable current and voltage for the light source to ensure that the light source can emit light normally. The light source circuit is connected to the light source through electrical connection. In this way, when the sensing element 30 wakes up the light source, the light source circuit can provide the required electrical energy for the light source to make it emit light. The working principle of the light source circuit is based on the circuit principle. Through reasonable circuit design and component selection, the function of providing stable electrical energy for the light source is realized. The light source circuit usually includes components such as a power supply, resistors, and capacitors to ensure that the light source can work under appropriate current and voltage. And using the rigid circuit board 41 and the light source circuit as the light-emitting element 40 has multiple advantages. First, the rigid circuit board 41 provides a stable support structure, protecting the light source circuit and the light source from external interference and damage. Second, the light source circuit can provide stable electrical energy for the light source to ensure the uniformity and durability of the light-emitting effect. Finally, due to the stability and durability of the rigid circuit board 41, the light-emitting element 40 can work stably for a long time in various environments, improving the reliability and service life of the product.

[0050] Further, referring to Figure 2 and Figure 5, in some embodiments of the present utility model, the positioning holes 11 on the positioning plate 10 are arranged in one-to-one correspondence with the positions of the light sources. This embodiment will further elaborate on the specific configuration relationship between the positioning plate 10, the positioning holes 11, and the light sources. In this embodiment, the positioning holes 11 on the positioning plate 10 are arranged in one-to-one correspondence with the positions of the light sources. This means that a corresponding light source is provided below each positioning hole 11 to ensure that when the user presses or approaches a certain button, the light source below the button will be awakened and emit light. To achieve this correspondence, the number and layout of the buttons are first determined, and then the positioning holes 11 are correspondingly formed on the positioning plate 10. Then, the light-emitting elements 40 are arranged below the positioning plate 10, and it is ensured that each light source is accurately located below a positioning hole 11. This one-to-one setting method brings multiple advantages. First of all, it improves the user's operation experience. When the user presses or approaches a certain button, the light source below the button will light up, providing intuitive visual feedback and enabling the user to clearly identify the button they are operating. Secondly, this setting method simplifies the circuit design and wiring process. Since each light source only corresponds to one button, it is easier to design the circuit and wiring, reducing the manufacturing cost and complexity. Finally, this one-to-one setting method also helps to improve the reliability and stability of the product. Since each light source works independently, even if one of the light sources fails, it will not affect the normal operation of other buttons.

[0051] Refer to Figure 1, in some embodiments of the present utility model, the key shaft 20 is provided with a light-transmitting portion 21, and the positions of the light-transmitting portion 21 and the light-emitting source are arranged in one-to-one correspondence. This embodiment will further elaborate on the specific configuration relationship between the key shaft 20, the light-transmitting portion 21, and the light-emitting source. In this embodiment, a light-transmitting portion 21 is specifically provided on the key shaft 20. This design enables the light emitted by the light-emitting source to pass through the key shaft 20 and then emit light. Importantly, the position of the light-transmitting portion 21 is arranged in one-to-one correspondence with the position of the light-emitting source, which means that a corresponding light-emitting source is provided below each light-transmitting portion 21. To achieve this correspondence, first ensure that the light-transmitting portion 21 on the key shaft 20 has sufficient transparency and smoothness so that light can pass through smoothly. Then install the key shaft 20 on the positioning plate 10 and ensure that each light-transmitting portion 21 accurately covers the top of a light-emitting source. The setting of the light-transmitting portion 21 brings multiple advantages and applications. First, it enhances the visual effect of the illuminated key assembly. When the user presses or approaches the key, the light emitted by the light-emitting source will pass through the light-transmitting portion 21, forming a unique lighting effect and bringing a new visual experience to the user. Second, the setting of the light-transmitting portion 21 makes the illuminated key assembly more flexible and variable. By changing the shape, size, and position of the light-transmitting portion 21, various different lighting effects can be created to meet the user's needs for personalization and customization. Finally, the application of the light-transmitting portion 21 further improves the user's operation experience. Since the light can be emitted through the key shaft 20, the user can more clearly see the position and state of the key when operating the key, thereby improving the accuracy and comfort of the operation.

[0052] Furthermore, in some embodiments of the present utility model, the light-transmitting portion 21 includes at least one of a light-transmitting hole, a light guide column, and a light homogenizing portion. This embodiment will further elaborate on the specific structure and configuration of the light-transmitting portion 21. The light-transmitting portion 21 is an important part of the key shaft 20, which is responsible for transmitting the light emitted by the light-emitting source through the key shaft 20 and emitting light. In this embodiment, the light-transmitting portion 21 includes at least one of a light-transmitting hole, a light guide column, and a light homogenizing portion. These structures can exist alone or in combination to achieve different lighting effects.

[0053] The light-transmitting holes are one or more small holes formed in the key shaft 20, which allow light to directly pass through the key shaft 20 and emit. The shape, size and position of the light-transmitting holes can be designed according to needs to achieve different lighting effects. For example, the light-transmitting holes can be set in shapes such as circular, square, oval, etc., and can be located at the center or edge of the key shaft 20. The light guide column is one or more columnar structures provided on the key shaft 20, which is used to guide the light to propagate inside the key shaft 20 and emit the light from the side or top of the key shaft 20. The light guide column can be made of transparent or translucent materials to ensure that the light can propagate and emit smoothly. By adjusting the shape, size and position of the light guide column, different lighting effects and light propagation paths can be achieved. The light homogenizing part is one or more structures provided on the key shaft 20 for evenly distributing light. It can diffuse and evenly distribute the light emitted by the light source, so that the entire key shaft 20 emits a soft and uniform lighting effect. The light homogenizing part can be made of materials with scattering properties, such as frosted glass or diffuser sheets, etc., to ensure that the light can be evenly distributed on the surface of the key shaft 20.

[0054] In practical applications, the light-transmitting parts 21 can be combined and used according to needs to achieve more complex and diverse lighting effects. For example, the light-transmitting holes and the light guide columns can be combined and used, so that the light can not only directly emit through the light-transmitting holes, but also propagate inside the key shaft 20 through the light guide columns and emit from the side. Or, the light homogenizing part can be combined with the light-transmitting holes or the light guide columns to achieve a softer and more uniform lighting effect. The application of the light-transmitting part 21 further improves the user's operation experience. In a relatively dark environment, the soft light emitted by the light-transmitting part 21 can help the user more clearly identify the position and state of the keys, improving the accuracy and comfort of the operation.

[0055] Refer to Figure 2 and Figure 5In some embodiments of the utility model, a shaft pad 42 is provided between the key shaft 20 and the light emitting element 40. This embodiment will further elaborate on the setting and function of the shaft pad 42 between the key shaft 20 and the light emitting element 40. In the light emitting key assembly, a shaft pad 42 is specially provided between the key shaft 20 and the light emitting element 40. The shaft pad 42 is a gasket or a layered structure located below the key shaft 20 and adjacent to the light emitting element 40. It is mainly made of soft and elastic materials, such as silicone, rubber, etc., to ensure a good touch and buffering effect during the key operation. The setting of the shaft pad 42 brings multiple functions. First, it plays a buffering role. When the user presses the key, the shaft pad 42 can absorb part of the impact force, reduce the direct pressure of the key shaft 20 on the light emitting element 40, and thus protect the light emitting element 40 from damage. Secondly, the shaft pad 42 also provides a good touch. Its softness and elasticity allow the user to feel a more comfortable and smooth operation experience when pressing the key. Finally, the shaft pad 42 also helps to reduce the noise during key operation, making the entire key assembly quieter and more comfortable.

[0056] In actual applications, the under-shaft pad 42 can be customized and designed as needed. For example, the under-shaft pad 42 of different materials, thicknesses and shapes can be selected to meet different usage requirements and visual effects. At the same time, the under-shaft pad 42 can also work closely with the key shaft 20 and the light-emitting element 40 to ensure good stability and buffering effect during the entire key operation process. In addition, the installation of the under-shaft pad 42 is also very simple. During the manufacturing process, it is only necessary to place the under-shaft pad 42 between the key shaft 20 and the light-emitting element 40 and ensure close contact between them. This simple installation method not only improves production efficiency, but also reduces manufacturing costs. In summary, the luminous key assembly of this embodiment achieves a good buffering effect, a comfortable touch and noise reduction function by adopting the design of setting the under-shaft pad 42 between the key shaft 20 and the light-emitting element 40, thereby further improving the user's operating experience and the overall performance of the product.

[0057] Reference Figure 2 as well as Figure 5, in some embodiments of the present utility model, a positioning groove 12 is provided at the upper end of the positioning plate 10, and the sensing element 30 is disposed in the positioning groove 12. In this embodiment, the positioning groove 12 is specifically provided at the upper end of the positioning plate 10. This positioning groove 12 is a groove or cavity for accommodating and fixing the sensing element 30, which ensures that the sensing element 30 can be stably mounted on the positioning plate 10 and will not move or fall off during the key operation process. The sensing element 30 is disposed in the positioning groove 12, and this design enables the sensing element 30 to accurately sense the movement state of the key shaft 20 and wake up the corresponding light source when needed. At the same time, since the sensing element 30 is firmly fixed in the positioning groove 12, it is also well protected from being damaged due to external impact or vibration.

[0058] In some embodiments of the present utility model, the light-emitting element 40 has a ground wire (not shown in the figure), and the ground wire is disposed outside the induction coil 321. In this embodiment, in addition to having the light-emitting function, the light-emitting element 40 is specifically designed with a ground wire. The main function of this ground wire is to ensure the electrical stability and safety of the light-emitting element 40 during the working process. In order to avoid unnecessary interference of the ground wire on the induction coil 321, the ground wire is specifically disposed outside the induction coil 321. Specifically, the light-emitting element 40 is firmly mounted on the positioning plate 10, and its ground wire is cleverly arranged outside the induction coil 321. This design not only ensures the electrical connection stability of the light-emitting element 40 but also avoids the electrical interference between the ground wire and the induction coil 321, thereby ensuring that the induction coil 321 can accurately sense the movement state of the key shaft 20.

When the user is using the keyboard, the sensing element 30 of the light-emitting key assembly can sense the position of the user's finger, thereby waking up the corresponding light source on the light-emitting element 40. The light emitted by the light source can then pass through the key shaft 20, so that it is convenient for the user to observe the position of the keys on the keyboard and the key information, thus facilitating the user's use and improving the user experience.
