Description

Technical Field

[0001] The present application relates to a switch button, in particular to a switch button with adjustable feedback elasticity. Background Art

[0002] In modern electronic products, switch buttons are one of the core components of human-computer interaction, and their design and performance are crucial to the user experience. Traditional switch button technology mainly provides button feedback force through a fixed spring system, but this design is often difficult to meet the user's personalized needs for feedback force in changing application scenarios. Most of the existing switch buttons use a preset spring compression amount to determine the button feedback feeling. Although this method solves the basic tactile feedback problem to a certain extent, it lacks flexibility and adjustability and cannot provide a diverse button experience according to different usage needs.

[0003] The deficiencies of the prior art are mainly reflected in two aspects: First, since the compression amount of the spring is usually fixed and cannot be adjusted according to the different needs of users, in some scenarios, users may feel that the key feedback is too soft or too stiff, which affects the comfort and experience of use. Secondly, the existing key system cannot cope with changes in different operation intensities and frequencies. For example, in some high-frequency operation scenarios, excessive rebound force may cause key fatigue, while too weak rebound force may affect the clear feedback of the key, resulting in inaccurate or unsmooth operation. The root cause of these deficiencies is that the prior art has failed to effectively introduce a feedback adjustment mechanism, and has not taken into account the different needs of users for rebound force during actual use.

[0004] In order to solve the above problems, it is particularly important to develop a switch button technology with an adjustable feedback elastic force function. Summary of the invention

[0005] The purpose of the present application is to overcome at least one of the shortcomings of the prior art and to provide a switch button with adjustable feedback elasticity. The switch button can adjust the initial compression amount of the spring by setting a knob at the bottom. It can not only adjust the rebound feel according to specific needs, but also adapt to a variety of usage scenarios.

[0006] To achieve the above-mentioned purpose, the present application discloses a switch button with adjustable feedback elastic force, which includes a shell, a shaft rod inserted into the shell, and a reset spring located in the shell for resetting the shaft rod, wherein the shaft rod is matched with the shell by insertion, and the shaft rod has an upper stop constrained by the shell, and the stop limit the displacement of the shaft rod in the up and down directions; a guide structure matched with the shaft rod is provided inside the shell, and the structure can guide the shaft rod to slide in a straight line direction, thereby ensuring the stable movement of the shaft rod in the shell; an opening opposite to the shaft rod is provided at the bottom of the shell, and at the same time, a ring platform is formed by extending upward at the edge of the opening position in the shell, and the ring platform is provided with a clamping platform; a positioning knob is inserted from the bottom opening of the shell, and the outer wall surface of the positioning knob is provided with a plurality of clamping positions matched with the clamping platform in the height direction, and the clamping positions and the clamping platform cooperate to fix the positioning knob in the opening of the shell; a spring installation position for installing and fixing the reset spring is formed between the top of the positioning knob and the shaft rod, and the height position of the positioning knob is adjusted, thereby adjusting the pre-compression amount of the reset spring.

[0007] In some embodiments, a magnetic block is provided on the side surface of the shaft rod, and correspondingly, a Hall device opposite to the magnetic block is provided on the inner side surface of the shell.

[0008] Compared with the prior art, the present invention has at least one of the following beneficial effects: 1. Feedback elastic force adjustability: By adjusting the initial compression of the spring through the knob at the bottom, the rebound feel of the key can be adjusted according to the user's personalized needs, providing a more flexible key experience and solving the problem of fixed spring compression in traditional technology.

[0009] 2. Adapt to various usage scenarios: The elastic force adjustment mechanism of the switch button enables it to adapt to different operating intensities and frequencies. Whether it is high-frequency operation or occasions requiring greater feedback, it can provide appropriate rebound force to enhance the user experience.

[0010] 3. Convenient adjustment and installation: The design of the adjustment knob allows the user to easily adjust the pre-compression of the spring. At the same time, its positioning with the housing ensures the fixation and stability of the knob, simplifying the installation and adjustment process.

[0011] The above-listed beneficial effects are not exhaustive of all advantages. Other potential beneficial effects and detailed technical implementations will be further disclosed in the examples or other description parts of this application. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] See attached Figure 1 This embodiment provides a switch button with adjustable feedback elastic force, aiming to solve the problem that the button feedback force in the prior art is not adjustable and cannot meet the personalized needs of different users. Specifically, this embodiment realizes the adjustable function of the button rebound force through innovative design, so that the feedback force can be flexibly adjusted according to actual use needs, thereby improving the user's operating comfort and experience. The technical solution of this application is described in detail below in combination with specific implementation methods.

[0018] As shown in the figure, the switch button of this embodiment includes a housing 1, a shaft 2, a reset spring 3, an adjustment knob 6, a clamping structure 7, and components such as a magnetic block and a Hall device. First, the housing 1 is made of high-strength engineering plastic material (such as polycarbonate PC or polyoxymethylene POM), which not only has good wear resistance and impact resistance, but also can effectively ensure stability in long-term use. A guide structure is designed inside the housing 1 to cooperate with the shaft 2, which is used to guide the shaft 2 to slide smoothly in a straight line direction to ensure the smoothness of the button operation. An opening is provided at the bottom of the housing 1, and a ring 4 is extended upward at the edge of the opening to hold the adjustment knob 6.

[0019] The shaft 2 is made of high-strength non-metallic material (such as reinforced nylon PA6 or polytetrafluoroethylene PTFE), which not only has good mechanical properties but also has a low friction coefficient, which helps to improve the durability and comfort of the key. The shaft 2 is matched with the housing 1 by insertion, and an upper stop is provided on the shaft 2 to limit its displacement in the up and down directions. The surface of the shaft 2 is finely processed so that it cooperates with the guide structure in the housing 1 to ensure the stability and accuracy of the shaft 2 during key operation. As one of the core components of the key, the reset spring 3 mainly provides a rebound force to ensure that the key can quickly return to its original position after being pressed. The reset spring 3 is made of highly elastic stainless steel or alloy material, which has excellent elasticity and durability.

[0020] The positioning knob 6 is an innovative design of the present embodiment, which is inserted through the opening at the bottom of the housing 1. The outer wall of the knob 6 is provided with a plurality of latches 7 along the height direction, and these latches 7 cooperate with the latches 5 on the inner ring platform 4 of the housing 1 to ensure that the positioning knob 6 will not loosen during rotation, thereby ensuring the stability and controllability of the adjustment process. A spring mounting position is provided between the top of the knob 6 and the shaft 2 for installing and fixing the reset spring 3. By rotating the positioning knob 6, the user can adjust the pre-compression amount of the reset spring 3, and then adjust the rebound force of the button. Specifically, in the process of rotating the positioning knob 6, the compression amount of the reset spring 3 changes, and the magnitude of the feedback force also changes accordingly. By adjusting the strength of the rebound force, the user can select the appropriate button feedback force according to different needs.

[0021] In some embodiments, a magnetic block is provided on the side of the shaft 2, and a Hall device opposite to the magnetic block is provided on the inner side of the housing 1 for real-time detection of the displacement of the shaft 2. The Hall device outputs a corresponding signal according to the relative position change of the magnetic block. This design not only helps to provide precise resilience adjustment, but also can be expanded to other intelligent control functions, such as automated feedback or enhanced tactile perception.

[0022] Specifically, the design of the adjustment knob 6 ensures the stability and controllability of the adjustment process. During the adjustment process, the user rotates the adjustment knob 6, and the knob 6 moves along the height direction, driving the spring mounting position to move up and down, thereby adjusting the pre-compression of the reset spring 3. The magnitude of the rebound force is determined by the compression of the reset spring 3. When the compression is large, the rebound force is strong and the feedback is more obvious; when the compression is small, the rebound force is weak and the feedback is softer. During each rotation, the positioning position 7 of the adjustment knob 6 cooperates with the positioning table 5 to produce a locking feeling, ensuring that the knob 6 can be stably fixed after being adjusted to the appropriate position, avoiding loosening during use, and ensuring that the adjusted rebound force is continuous and stable.

[0023] Through this design, users can flexibly adjust the feedback force according to actual needs. For high-frequency operation occasions, users can choose a weaker rebound force to reduce the fatigue of key operation; in occasions where precise tactile feedback is required, a stronger rebound force can provide clear tactile feedback to ensure the accuracy of operation. After completing the adjustment, the user can press the switch button to perform actual operation to test whether the rebound force meets the requirements. If the rebound force is too strong or too weak, the user can rotate the adjustment knob 6 again to fine-tune the feedback force until the ideal feel is achieved.

[0024] The switch button of this embodiment has the function of flexibly adjusting the feedback force, and can provide personalized rebound feedback according to different operation requirements and usage scenarios, further improving the user experience. For example, in frequently operated devices such as smart phones, mice, keyboards, etc., users can choose a lighter rebound force to reduce operating fatigue; and in situations where precise tactile feedback is required, such as game controllers or professional equipment, a stronger rebound force can help users accurately perceive the response of the button and avoid misoperation. In addition, the switch button is also suitable for smart homes, automotive electronics, medical equipment and other fields. By adjusting the strength of the rebound force, it can better meet the needs of different usage environments and improve the user experience.

[0025] In summary, the switch button with adjustable feedback elastic force in this embodiment realizes the adjustable function of the button feedback force through the innovative design of the adjustment knob 6 structure. This design not only meets the personalized needs of users, but also ensures the stability and long-term durability of the button. By selecting suitable materials and precise adjustment mechanisms, the present invention can provide a more flexible and comfortable operating experience, and is widely applicable to various electronic products that require tactile feedback.

[0026] 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 scope of protection of the present disclosure as defined by the claims.
