Description

TECHNICAL FIELD

[0001] The application relates to the field of keys, in particular to an optical axis key which improves the operation sound feedback by operation bottoming. BACKGROUND

[0002] In the field of mechanical keyboards, optical axis keys, as an important key technology, are widely used in various high-end keyboard products. Traditional optical axis keys usually use a bottom-mounted photoelectric component to realize key triggering. This design makes the shaft rod not directly contact the bottom surface of the keyboard shell when the key is pressed, thereby avoiding physical friction between the key and the shell. This non-touching working form improves the durability and response speed of the key to a certain extent, but also brings some non-negligible shortcomings.

[0003] Due to the lack of direct physical feedback during the operation of the key, the pressing sound of the traditional optical axis key is often not crisp enough, and it is difficult to achieve the "HIFI" effect pursued in the industry. This deficiency in sound not only affects the user's experience, but also to a certain extent, reduces the high-end positioning of the keyboard. In addition, the unclear feedback sound of the key may also cause the user to be unable to accurately perceive the triggering state of the key during fast typing or game operation, thereby affecting the accuracy and efficiency of the operation.

[0004] The main reason for the above-mentioned shortcomings is the structural design of the existing optical axis key. Since the shaft rod does not touch the bottom, the key lacks the necessary acoustic feedback path during the pressing process, resulting in limited sound propagation when the key is triggered. In addition, although the bottom-mounted design of the photoelectric component optimizes the response performance of the key, it does not effectively support and enhance the sound feedback. Therefore, while the existing technology pursues the response speed and durability of the key, it ignores the high requirements of users for the key touch and sound experience.

[0005] In view of the above problems, it is particularly important to develop a new type of optical axis key technology. CONTENT OF THE INVENTION

[0006] The purpose of the present application is to at least overcome at least one of the deficiencies of the prior art, and to provide an optical axis key which, by optimizing and improving the structure of the key, can enhance the acoustic feedback effect of the key while maintaining the advantages of fast response and high durability of the optical axis key, and achieve a crisp key sound of "HIFI" level.

[0007] To achieve the above object, the application discloses a light axis key, which comprises a shell, a shaft body slidably inserted into the shell, a photoelectric component in the shell, and a light control piece connected with the shaft body and opposite to the photoelectric component, wherein the shaft body drives the light control piece to move synchronously for triggering the photoelectric component; the shaft body has a linear sliding stroke in the shell, and the shaft body has a shaft rod towards the inner bottom surface of the shell, the shaft rod has a solid bottom end, and the distance between the solid bottom end and the inner bottom surface of the shell is less than the linear sliding stroke of the shaft body, so that the solid bottom end is in contact with the inner bottom surface of the shell during the operation of the key and makes a sound by impact.

[0008] As an optional technical solution, the photoelectric component and the light control piece form a pair of shooting type trigger mechanism, specifically, the light control piece is a light shielding piece with a light transmission area; the photoelectric component comprises a PCB board, a light emitting end and a light receiving end mounted on the PCB board, the light emitting end and the light receiving end are opposite to form a light path, and the light shielding piece is located in the light path; when the shaft body moves, the light transmission area is controlled to be opposite to the light path, and then the light path is controlled to be on / off.

[0009] Further, in order to avoid the light shielding piece stroke, the PCB board is divided into two independent areas for mounting the light emitting end and the light receiving end, or an avoiding opening is formed on the PCB board.

[0010] As an optional technical solution, the photoelectric component and the light control piece form a reflection type trigger mechanism, specifically, the light control piece is a reflection piece provided with a light reflection area; the photoelectric component comprises a PCB board, a light emitting end and a light receiving end mounted on the PCB board, the light emitting end and the light receiving end are arranged on the same side and in the same direction, and are simultaneously matched with the reflection piece; when the shaft body moves, the reflection area is controlled to match the light emitting end and the light receiving end, so that a reflection light path is formed between the light emitting end and the light receiving end, and then the light path is controlled to be on / off.

[0011] Further, the PCB board is directly or indirectly connected with the pin extending out of the shell.

[0012] As an optional technical solution, the solid bottom end of the shaft rod is spherical.

[0013] Compared with the prior art, the application has at least one of the following beneficial effects:

[0014] 1. Enhanced acoustic feedback effect: by optimizing the structure of the light axis key, especially by designing the solid bottom end to contact the bottom surface of the shell, the sound feedback of the key is improved, a crisp impact sound is produced when pressing, and the "HIFI" effect pursued by the industry is achieved. This improvement not only improves the use experience of the key, but also enhances the high-end positioning of the keyboard.

[0015] 2. Improved operation accuracy: The newly designed optical axis button provides clear physical feedback through the bottom touch design during the button triggering process, helping users more clearly perceive whether the button is triggered, avoiding the uncertainty of operation caused by unclear sound in traditional optical axis buttons, especially in fast typing or game operation, users can more accurately perceive the button state.

[0016] 3. Maintaining high responsiveness and durability: By moving the light and electrical components upwards, the application improves sound feedback through bottom touch design, while still maintaining the fast response and high durability of traditional optical axis buttons. The sliding stroke of the shaft body and the design of the photoelectric components ensure the speed and accuracy of the button response, without affecting the long-term service life of the button.

[0017] 4. Diverse triggering methods: The application provides two photoelectric triggering methods, reflection and reflection, which can be selected according to different design needs. This flexibility allows the optical axis button to adapt to different mechanical keyboard design needs, while also improving the application scenarios of optical axis buttons in optical sensing technology.

[0018] The above listed benefits are not exhaustive of all advantages. Other potential benefits and detailed technical implementations will be further disclosed in the embodiments or other description sections of the present application. BRIEF DESCRIPTION OF DRAWINGS

[0026] Referring to the drawings Figure 1 In the embodiments, the main components of the optical axis key include a shell 1, a shaft body 2, a shaft rod 3, a solid bottom end 4, a light emitting end 5, a light receiving end 6, a light shield 7, a light transmission area 8, a reflecting sheet 9, and a reflecting area 10. The components and their cooperation will be described in detail below.

[0027] First, the shell 1 is the outer shell of the entire optical axis key, and is designed in a sealed structure to form a closed cavity to ensure that the internal photoelectric components are not disturbed by external light. The inner wall surface of the shell 1 is smooth and has certain strength and durability to ensure that the key can work stably during use. A shaft body 2 is slidably inserted into the shell, and the sliding stroke of the shaft body 2 is designed to fully match the space inside the shell, thereby ensuring that the shaft body can move smoothly without jamming.

[0028] The shaft body 2 is connected to the light control member, and the movement of the shaft body 2 controls the switching of the light path. Specifically, the movement of the shaft body 2 drives the synchronous movement of the light control member 7 or 9, and by adjusting the cooperation between the light transmission area 8 or the reflecting area 10 and the photoelectric components 5, 6, the generation of the operation signal is triggered. The movement of the shaft body 2 is guided by the shaft rod 3, which has a root facing the bottom surface of the shell, and a solid bottom end 4 is provided on the shaft rod 3, and the shape and size of the bottom end 4 are designed to ensure that the bottom end 4 is in contact with the inner bottom surface of the shell during key operation.

[0029] The entity design of the bottom end 4 is to solve the problem of insufficient sound of the traditional optical shaft key. In the traditional optical shaft key, there is no direct contact between the shaft body and the inner bottom surface of the shell, resulting in a lack of crisp feedback sound when the key is pressed. The entity bottom end 4 of the shaft rod 3 in the embodiment will collide with the inner bottom surface of the shell when the key is working, and the sound produced by the collision will be transmitted through the shell, forming a crisp sound and providing a sound feedback similar to "HIFI" effect. This design effectively improves the user experience of the key, especially for gamers or user groups that require high-precision key feedback.

[0030] The light emitting end 5 is usually a light emitting diode (LED), and the light receiving end 6 is usually a photoelectric crystal such as a photodiode. Referring to FIG. 4, the light emitting end 5 and the light receiving end 6 are mounted on the PCB board and form a reflection type trigger mechanism. Specifically, when the movement of the shaft body 2 drives the light shielding sheet 7 or the reflecting sheet 9, the light transmission area 8 of the light shielding sheet or the reflection area 10 of the reflecting sheet will be opposite to the light emitting end 5 and the light receiving end 6, thereby realizing the on-off of the light path. This design ensures that the key can accurately trigger the signal when pressed, and at the same time realizes the high response speed and long service life of the optical trigger. Figure 1

[0031] In specific implementation, the light emitting end 5 and the light receiving end 6 on the PCB board are adapted to the movement track of the shaft body through independent areas or avoidance openings, avoiding the interference of the light shielding sheet 7 or the reflecting sheet 9. The PCB board is also connected with the shell through pins to ensure that the photoelectric signal can be smoothly transmitted.

[0032] As another embodiment, referring to FIG. 5, the reflecting sheet 9 of the reflection type trigger mechanism is provided with a reflection area 10, and when the shaft body 2 drives the reflecting sheet 9 to move, the reflection area 10 will form a reflected light path with the light path between the light emitting end 5 and the light receiving end 6, achieving the same triggering purpose as the reflection type trigger mechanism. Figure 2

[0033] In summary, the optical shaft key of the embodiment can provide crisp sound feedback on the basis of ensuring high response speed and long durability of the key through the unique shaft rod design and cooperation with the photoelectric component. This design not only solves the problem of insufficient feedback of the traditional optical shaft key, but also improves the user experience, especially suitable for application scenarios with high requirements for key touch and sound feedback.

[0034] Although the exemplary embodiments of the present disclosure have been described, it should be understood by those skilled in the art that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence. Therefore, all changes and modifications are included in the protection scope of the present disclosure defined by the claims. The present disclosure is defined by the appended claims, and the equivalents of these claims are also included.​​
