Description

Technical Field

[0001] The utility model relates to the field of keyboard switches, in particular to a thin keyboard switch and a keyboard with a side-mounted magnet. Background Art

[0002] In traditional keyboard switch designs, the placement of magnets has certain limitations. Magnets are usually placed in the middle bottom of the button. Although this layout meets the basic magnetic sensing requirements to a certain extent, it has obvious shortcomings. Specifically, the position of magnets in traditional designs limits the design flexibility of keyboard switches. Since the magnets must maintain a certain distance and position relationship with the guide channel of the base, the overall size and shape of the keyboard switch are limited. For keyboard products that pursue a thin and light design, this limitation will become a major obstacle. Utility Model Content

[0003] In view of this, the utility model provides a thin keyboard switch with a magnet placed on the side, and the top of the magnet column is designed to extend out of the upper surface of the upper cover. This innovative design greatly expands the installation space of the magnet, so that the volume of the magnet is no longer limited by the limited chamber space between the upper cover and the base, and the height of the magnet is effectively increased. Even in a limited space, it can provide stronger magnetic force and achieve efficient magnetic field distribution.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] A thin keyboard switch with a magnet placed on the side, comprising a base, an upper cover, a button, a spring and a PCB board, wherein the button is slidably mounted on the base, the top of the button protrudes from the upper cover, a downwardly protruding positioning column is provided in the middle of the button, a magnet column is provided on the side of the button, a mounting hole is provided at the bottom of the magnet column, a magnet is installed in the mounting hole, a guide channel is provided at the bottom of the base, and when the button descends to the end of the stroke, the positioning column and the guide channel move relative to each other, and the top of the magnet column protrudes from the upper surface of the upper cover.

[0006] Its design cleverly overcomes the thickness limitation of traditional keyboard switches. The switch includes components such as a base, an upper cover, a button, a spring and a PCB board. The button and the base are installed by sliding fit to ensure smooth operation. The top of the button extends out of the upper cover, and a positioning column protruding downward is provided in the middle. A magnet column is provided on the side, and a mounting hole is provided at the bottom of the magnet column for fixing the magnet. A guide channel is provided at the bottom of the base. When the button moves downward to the end of the stroke, the positioning column and the guide channel move relative to each other, ensuring a precise trigger mechanism. The top of the magnet column is designed to extend out of the upper surface of the upper cover. This innovative design greatly expands the installation space of the magnet. In the traditional keyboard switch design, the volume of the magnet is often limited by the limited chamber space between the upper cover and the base, making it difficult to achieve efficient magnetic field distribution. This new thin keyboard switch effectively increases the height of the magnet by allowing the top of the magnet column to extend, providing stronger magnetic force even in a limited space, which is particularly important for thin keyboard switches.

[0007] The advantages of this design are obvious: first, it greatly improves the magnetic force of the magnet, allowing the keyboard switch to provide good tactile feel and response speed while maintaining a thin design. Second, since the volume of the magnet is no longer limited, designers can more flexibly adjust the size and shape of the magnet to suit different application requirements. Finally, this design also helps to improve the overall performance and durability of the keyboard switch because it allows the use of larger and stronger magnets, thereby improving the stability and reliability of the switch.

[0008] This thin keyboard switch with a magnet on the side uses an innovative design with the top of the magnet column extending out. It not only breaks through the thickness limitations of traditional keyboard switches, but also improves the performance of the switch and user experience. It is an important technological innovation in the trend of lightweight and thin modern electronic devices.

[0009] Preferably, a buckle is provided on the outer periphery of the upper cover or the base, and the buckle is snap-connected with the PCB board.

[0010] The introduction of the buckle not only simplifies the assembly process, but also significantly enhances the connection stability between the keyboard switch and the PCB board, so that it will not shake easily even during frequent key operations. This stable connection relationship ensures the precise transmission of magnetic induction intensity, so that each key operation can get accurate feedback, thereby improving the response accuracy and user experience of the entire keyboard system.

[0011] Preferably, there are multiple buckles, and the multiple buckles are evenly distributed on the periphery of the upper cover or the base.

[0012] There are not just one but multiple buckles, which are evenly distributed around the outer periphery of the upper cover or base. This multi-point fixing design concept firmly supports the keyboard switch like stars, so that each buckle can share part of the stress, thus greatly enhancing the overall structural strength and stability. This design not only improves assembly efficiency, but also ensures the durability and reliability of the keyboard switch during long-term use.

[0013] Preferably, a channel column extending downward is provided at the bottom of the base, and the guide channel is provided at the center of the channel column.

[0014] The limited vertical space inside the keyboard switch is cleverly utilized. By setting up a downward-extending channel column, the spring can be lengthened, which means that the spring can provide a larger elastic force range. At the same time, the positioning column of the button is also extended, increasing the length of the tube position, thereby optimizing the button travel feel. With this design, the button can remain stable whether it is during rapid continuous tapping or long-term typing, reducing unnecessary shaking, thus providing users with a more stable and comfortable operating experience.

[0015] Preferably, the magnet column is dug with a through hole, and the through hole is connected to the mounting hole.

[0016] In the design of the magnet column, the introduction of the through hole is also an innovative improvement. This through hole is connected to the mounting hole and plays a vital role in the installation process of the magnet. When the magnet is placed in the opening at the top of the magnet column, the through hole plays the role of exhaust. In the process of contact between the magnet and the magnet column, the air can be discharged smoothly through the through hole, which helps the magnet to enter the installation position more smoothly and reduces the resistance during the installation process. The existence of the through hole also provides a visual inspection method for the staff. Through the through hole, the staff can visually observe whether the magnet has been fully installed in place or whether there are any abnormalities. This instant visual feedback greatly improves the accuracy and efficiency of the installation process, while also reducing the risk of product failure caused by improper installation of the magnet. This design not only simplifies the installation process of the magnet and increases the assembly speed, but also enhances the reliability and stability of the product. The design of the through hole cleverly solves the exhaust problem during the installation of the magnet, and also provides a simple and effective means for quality control. This innovative design not only improves the overall performance of the product, but also brings a better user experience to users.

[0017] Preferably, the upper portion of the spring is sleeved on the positioning column, and the lower portion is sleeved on the outer periphery of the guide channel.

[0018] The upper part of the spring is sleeved on the positioning column, and the lower part is sleeved on the guide channel, providing stable support and precise control for the button. This design ensures the stability and durability of the spring throughout the use process. The positioning column serves as a fixing point for the spring, ensuring that the spring can move along the predetermined path when pressed and released. The guide channel provides a smooth movement trajectory for the spring, reducing friction and wear, and extending the service life of the spring.

[0019] Preferably, the PCB board is arranged at the bottom of the base, and a Hall element is installed on the PCB board for induction with the magnet to form a signal input; the PCB board is provided with a Hall element state detection circuit and a main control circuit, and the Hall element is connected through the Hall element state detection circuit and the main control circuit.

[0020] The layout optimization of the PCB board is also one of the highlights of this improvement. Placing the PCB board at the bottom of the base not only saves space, but also improves the stability of the circuit board. Hall elements that cooperate with magnets to sense and form signal input are installed on the PCB board. These Hall elements are connected to the main control circuit through the Hall element state detection circuit to form a highly integrated electronic control system. This design enables the keyboard switch to monitor and control the state of each key position in real time, improving the response speed and accuracy of the keyboard. In addition, the integration of the Hall element state detection circuit and the main control circuit on the PCB board also provides more functional expansion possibilities for the keyboard switch. For example, through programming, advanced functions such as macro definition and shortcut keys can be realized to meet the personalized needs of different users. At the same time, this design also makes the keyboard switch easier to upgrade and maintain, providing convenience for future functional expansion.

[0021] The utility model also provides a keyboard, comprising the keyboard switch with the magnet placed on the side as described above.

[0022] Compared with the prior art, the utility model has the following beneficial effects:

[0023] The thin keyboard switch with magnets placed on the side of the utility model cleverly overcomes the thickness limitation of traditional keyboard switches. The switch includes components such as a base, an upper cover, a button, a spring and a PCB board, wherein the button and the base are installed by sliding cooperation to ensure smooth operation. The top of the button extends out of the upper cover, the middle is provided with a positioning column protruding downward, the side is provided with a magnet column, and the bottom of the magnet column is provided with a mounting hole for fixing the magnet. A guide channel is provided at the bottom of the base, and when the button descends to the end of the stroke, the positioning column and the guide channel move relative to each other, ensuring a precise triggering mechanism. The top of the magnet column is designed to extend out of the upper surface of the upper cover. This innovative design greatly expands the installation space of the magnet. In the traditional keyboard switch design, the volume of the magnet is often limited by the limited chamber space between the upper cover and the base, making it difficult to achieve efficient magnetic field distribution. However, this new thin keyboard switch effectively increases the height of the magnet by allowing the top of the magnet column to extend, and can provide stronger magnetic force even in a limited space, which is particularly important for thin keyboard switches.

[0034] The present embodiment provides a thin keyboard switch with a magnet placed on the side, comprising a base 100, an upper cover 200, a button 300, a spring 400 and a PCB board.

The top of the magnet column 320 is designed to extend out of the upper surface of the upper cover 200. This innovative design greatly expands the installation space of the magnet 500. In the design of traditional keyboard switches, the volume of the magnet 500 is often limited by the limited chamber space between the upper cover 200 and the base 100, making it difficult to achieve efficient magnetic field distribution. The new type of thin keyboard switch effectively increases the height of the magnet 500 by extending the top of the magnet column 320, and can provide a stronger magnetic force even in a limited space, which is particularly important for a thin keyboard switch.

[0037] This thin keyboard switch with magnet 500 on the side has an innovative design with magnet column 320 extending from the top. It not only breaks through the thickness limitation of traditional keyboard switches, but also improves the performance of the switch and user experience. It is an important technological innovation under the trend of lightweight and thin modern electronic devices.

[0038] In this embodiment, a buckle 600 is disposed on the outer periphery of the upper cover 200 or the base 100 , and the buckle 600 is buckled with the PCB board.

[0039] The introduction of the buckle 600 not only simplifies the assembly process, but also significantly enhances the connection stability between the keyboard switch and the PCB board, so that it will not easily shake even during frequent key operations.
