Description

Technical Field

[0001] The utility model relates to the field of buffer buttons, in particular to a buffer button and a keyboard switch. Background Art

[0002] In the prior art, keyboard switches are an important part of the human-computer interaction interface, and their design directly affects the user's operating experience and the durability of the device. Traditional keyboard switches and buttons are mostly made of hard materials, such as POM / POK / PC. Although these materials perform well in terms of structural strength and tactile feedback, they have obvious limitations in practical applications.

[0003] Users often experience hand fatigue when using hard material buffer buttons for a long time or with high frequency of clicks. This is because hard materials cannot effectively absorb and disperse the impact force when in contact, causing the user's fingers to bear a large reaction force. This design not only affects the user's comfort, but also over time, the hard material may wear, scratch or even break, thus shortening the service life of the button.

[0004] In addition, the tactile feedback of hard materials is relatively simple, lacking in variety and layering, which limits the user's sensory experience to a certain extent. In today's pursuit of efficient and comfortable operation, users have higher expectations for the tactile feedback of keyboard switch buttons, hoping to obtain more delicate and rich sensory stimulation. Utility Model Content

[0005] In view of this, the utility model provides a buffer button and keyboard switch. The buffer part is a core component, which adopts a soft material. Its softness is softer than the touch part and the knocking part, which not only ensures the normal tactile feedback of the button, but also effectively absorbs the impact force generated during the user's operation. At the same time, the soft texture of the buffer part also gives the button a unique tactile feedback, providing users with a more pleasant use experience.

[0006] The purpose of the utility model is achieved through the following technical solutions:

[0007] A buffer button comprises a touch portion, a buffer portion and a knock portion which are separately connected in sequence from top to bottom, wherein the buffer portion is softer than the touch portion and the buffer portion is softer than the knock portion.

[0008] The design of the buffer button cleverly integrates the three functional areas of the touch part, the buffer part and the knocking part, and realizes the clear hierarchy of the structure and the complementary functions through the split connection. As the core component, the buffer part adopts soft materials, which are softer than the touch part and the knocking part, which not only ensures the normal tactile feedback of the button, but also effectively absorbs the impact force generated during the user's operation. This innovative design enables the buffer part to produce a certain elastic deformation when it is hit, thereby significantly reducing the impact force when the button is hit downward. This shock absorption effect not only reduces the force burden on the user's fingers and improves the comfort of operation, but also helps to extend the service life of the button because the reduced impact force reduces mechanical wear. In addition, the design of the buffer button also takes into account the principles of ergonomics. Its moderate hardness and elastic deformation characteristics make it less likely for users to feel fatigue during long-term operation, thereby improving work efficiency and accuracy of operation. At the same time, the soft texture of the buffer part also gives the button a unique tactile feedback, providing users with a more pleasant experience.

[0009] Preferably, the touch portion or the knocking portion is provided with a striking column facing downward.

[0010] In the optimized buffer button design, a downward-extending impact column is specially added to the touch or tapping part. When the user touches or presses the button, the impact column first contacts the shell, and the buffer plays a vital role in this process. Since the buffer is made of a soft and elastic material, it can produce an effective buffering effect at the moment the impact column contacts the shell. The generation of this buffering effect means that the impact force transmitted to the shell by the impact column is greatly reduced, which in turn reduces the reaction force felt by the user's fingers. Therefore, even in the case of frequent or forceful operation, users can enjoy a soft and comfortable tapping feel, as if they are interacting with a flexible object rather than hard plastic or metal. In addition, the shock-absorbing function of the buffer also helps to reduce the noise generated by the impact. In an office environment or in an occasion where quietness is required, this low-noise design is undoubtedly a huge advantage. It not only improves the user's comfort, but also helps to maintain a quiet working atmosphere.

[0011] Preferably, a lower impact edge is provided on the side of the striking portion.

[0012] In this optimization scheme, the side of the knocking part is cleverly designed with a lower edge of the impact side. The addition of this design element brings a more precise and comfortable experience to the operation of the button. When the user presses the button, the lower edge of the impact side first contacts the shell, and the role of the buffer part in this process is particularly important. The buffer part is made of soft and elastic material, which can quickly produce elastic deformation at the moment when the lower edge of the impact side contacts the shell, thereby effectively absorbing and dispersing the impact force. This buffering mechanism greatly reduces the reaction force felt by the user's finger when pressing the button, making each tapping as if on a soft cushion, which is both comfortable and natural. In addition, since the impact force is effectively controlled, the impact sound is also reduced accordingly, which is particularly important in environments that need to be kept quiet, such as libraries, offices and other places. The low-noise design not only improves the comfort of use, but also helps to maintain a quiet working or learning environment. The design of the lower edge of the impact side also improves the response sensitivity and operation accuracy of the button. The existence of the lower edge of the side allows the button to trigger the action when it is lightly touched without pressing hard, which is a significant advantage for scenes that require long-term operation or quick response.

[0013] Preferably, the side of the buffer portion is provided with an impact-side upper edge.

[0014] The side of the buffer is carefully designed with an upper edge on the impact side. This design cleverly balances the operating force and feedback effect of the button. When the user releases the button and it rebounds upward, the upper edge on the impact side first contacts the shell, and at this time the soft material of the buffer plays its unique advantage. The soft and hard materials of the buffer can produce elastic deformation at the moment when the upper edge on the impact side contacts the shell. This deformation effectively absorbs and disperses the impact force during the rebound process. This shock absorption effect not only reduces the force burden on the user's hands and reduces the fatigue that may be caused by repeated operations, but also significantly reduces the impact sound generated during rebound. In environments that need to be kept quiet, such as libraries, offices and other places, this low-noise design is undoubtedly a huge advantage. The design of the upper edge on the impact side also improves the tactile feedback of the button. When the user releases the button, he can clearly feel the slight resistance and rebound action. This tactile feedback enhances the user's perception of the button operation, making the operation more intuitive and accurate. In addition, the soft texture of the buffer and the design of the upper edge on the impact side can better protect the internal mechanical structure and avoid damage caused by excessive impact, thereby extending the service life of the button.

[0015] Preferably, the touch portion is provided with a buckle facing downward, and the knocking portion is provided with a slot that cooperates with the buckle.

[0016] The touch part is equipped with a clever snap mechanism facing downward, while the knock part is equipped with a slot that perfectly matches it. This design not only ensures a secure connection between the components, but also provides a smooth and intuitive user experience during operation. The combination of the snap and the slot allows the touch part, the buffer part, and the knock part to be easily aligned during assembly and maintain a stable position relationship during use. This design simplifies the assembly process, reduces production costs, and also improves the overall quality and reliability of the product.

[0017] Preferably, the touch portion, the buffer portion and the knocking portion are connected by snapping, riveting, gluing, ultrasonic welding or two-color injection molding.

[0018] Through a variety of connection methods such as snap-fitting, riveting, gluing, ultrasonic welding or two-color injection molding, these parts are firmly combined together, which not only improves the mechanical strength of the product, but also ensures durability under various conditions of use. For example, snap-fitting and riveting provide physical locking, gluing and ultrasonic welding achieve close bonding through chemical or hot melting, and two-color injection molding is formed in one step during the production process to achieve structural integration. These methods together ensure the long-term stability and durability of the product.

[0019] Preferably, the buffer portion is made of soft material.

[0020] The buffer part is made of soft and elastic soft materials, which are widely used in occasions where buffering is required due to their excellent shock absorption performance. The selection of soft materials enables the buffer part to effectively absorb and disperse the impact force when the user operates the button, thereby protecting the user's fingers from being hit by hard objects and significantly reducing the noise generated during operation. In addition, this material also has good wear resistance and aging resistance, and can maintain stable performance in long-term use, ensuring the durability and reliability of the product.

[0021] Preferably, the touch part is made of a hard material, and the knocking part is made of a hard material.

[0022] The touch and tap parts are made of hard materials, which are selected for their high strength and good mechanical properties. The use of hard materials ensures that the touch and tap parts can provide clear tactile feedback and accurate operation response when the user operates. At the same time, hard materials can also resist wear and scratches in daily use, maintaining the appearance and touch of the product. In addition, the rigidity of the hard material also provides the necessary support for the overall structure of the button, ensuring the stability and reliability of the button in various usage environments.

[0023] A keyboard switch comprises the buffer button as described above.

[0024] Compared with the prior art, the utility model has the following beneficial effects:

[0025] The design of the buffer button of the utility model cleverly integrates the three functional areas of the touch part, the buffer part and the knocking part, and realizes the clear hierarchy of the structure and the complementary functions through the split connection. As the core component, the buffer part adopts a soft material, which is softer than the touch part and the knocking part, which not only ensures the normal tactile feedback of the button, but also effectively absorbs the impact force generated during the user's operation.

[0034] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other.

[0035] The technical solution in this application will be described below in conjunction with the accompanying drawings.

[0036] This embodiment provides a keyboard switch, including a buffer button 100 , a housing, a spring 200 , a terminal 300 and a contact sheet 400 , wherein the housing includes a base 500 and an upper cover 600 .

[0037] The buffer button 100 includes a touch portion 110 , a buffer portion 120 , and a knock portion 130 which are separately connected in sequence from top to bottom. The buffer portion 120 is softer than the touch portion 110 , and the buffer portion 120 is softer than the knock portion 130 .

[0038] The design of the buffer button 100 cleverly integrates the three functional areas of the touch part 110, the buffer part 120 and the knocking part 130, and realizes the clear hierarchy of the structure and the complementary functions through the split connection. As the core component, the buffer part 120 adopts a soft material, which is softer than the touch part 110 and the knocking part 130, which not only ensures the normal tactile feedback of the button, but also effectively absorbs the impact force generated during the user's operation. This innovative design enables the buffer part 120 to produce a certain elastic deformation when it is struck, thereby significantly reducing the impact force when the button is hit downward. This shock absorption effect not only reduces the force burden on the user's fingers and improves the comfort of operation, but also helps to extend the service life of the button, because the reduced impact force reduces mechanical wear. In addition, the design of the buffer button 100 also takes into account the principles of ergonomics. Its moderate hardness and elastic deformation characteristics make it difficult for users to feel fatigue during long-term operation, thereby improving work efficiency and accuracy of operation. At the same time, the soft texture of the buffer part 120 also gives the button a unique tactile feedback, providing users with a more pleasant use experience.

[0039] In this embodiment, the touch portion 110 is provided with a strike column 111 facing downward. In other embodiments, the strike column may also be provided on the knocking portion.

[0040] In the optimized design of the buffer button 100, the touch part 110 is specially provided with a downward extending impact column 111. When the user touches or presses the button, the impact column 111 first contacts the shell, and the buffer part 120 plays a vital role in this process. Since the buffer part 120 is made of a soft and elastic material, it can produce an effective buffering effect at the moment when the impact column 111 contacts the shell. The generation of this buffering effect means that the impact force transmitted to the shell by the impact column 111 is greatly weakened, thereby reducing the reaction force felt by the user's fingers. Therefore, even in the case of frequent or forceful operation, the user can enjoy a soft and comfortable tapping feel, as if interacting with an elastic object rather than hard plastic or metal. In addition, the shock absorption function of the buffer part 120 also helps to reduce the noise generated by the impact. In an office environment or an occasion where quietness is required, this low-noise design is undoubtedly a huge advantage. It not only improves the user's comfort, but also helps to maintain a quiet working atmosphere.

[0041] In other embodiments, a side of the striking portion 130 is provided with an impact-side lower edge 131 to replace the aforementioned impact column 111 for achieving downward impact.

[0042] In this optimized solution, the side of the knocking part 130 is cleverly designed with a lower edge 131 on the impact side. The addition of this design element brings a more accurate and comfortable experience to the operation of the button. When the user presses the button, the lower edge 131 on the impact side first contacts the shell, and the role of the buffer part 120 in this process is particularly important. The buffer part 120 is made of soft and elastic material, which can quickly produce elastic deformation at the moment when the lower edge 131 on the impact side contacts the shell, thereby effectively absorbing and dispersing the impact force. This buffer mechanism greatly reduces the reaction force felt by the user's finger when pressing the button, making each tapping feel like being on a soft cushion, which is both comfortable and natural. In addition, since the impact force is effectively controlled, the impact sound is also reduced accordingly, which is particularly important in an environment that needs to be kept quiet, such as libraries, offices and other places. The low-noise design not only improves the comfort of use, but also helps to maintain a quiet working or learning environment. The design of the lower edge 131 on the impact side also improves the response sensitivity and operation accuracy of the button. The presence of the lower side edge allows the button to be triggered with a light touch without having to press hard, which is a significant advantage for long-term operations or scenarios that require quick response.

[0043] In this embodiment, an impact-side upper edge 121 is disposed on the side of the buffer portion 120 .

[0044] The side of the buffer 120 is carefully provided with an impact side upper edge 121. This design cleverly balances the operating force and feedback effect of the button. When the user releases the button and it rebounds upward, the impact side upper edge 121 first contacts the shell, and at this time, the soft material of the buffer 120 plays its unique advantage. The soft and hard material of the buffer 120 can produce elastic deformation at the moment when the impact side upper edge 121 contacts the shell, and this deformation effectively absorbs and disperses the impact force during the rebound process. This shock absorption effect not only reduces the force burden on the user's hand and reduces the fatigue that may be caused by repeated operations, but also significantly reduces the impact sound generated during rebound. In an environment that needs to be kept quiet, such as libraries, offices and other places, this low-noise design is undoubtedly a huge advantage. The design of the impact side upper edge 121 also improves the tactile feedback of the button. When the user releases the button, he can clearly feel the slight resistance and rebound action. This tactile feedback enhances the user's perception of the button operation, making the operation more intuitive and accurate. In addition, the soft texture of the buffer portion 120 combined with the design of the upper edge 121 on the impact side can better protect the internal mechanical structure and avoid damage caused by excessive impact, thereby extending the service life of the button.

[0045] In this embodiment, the touch portion 110 is provided with a buckle 112 facing downward, and the knocking portion 130 is provided with a slot 132 matched with the buckle 112 .

[0046] The touch part 110 is provided with an ingenious buckle mechanism facing downward, and the knocking part 130 is equipped with a slot that perfectly matches it. This design not only ensures a stable connection between the components, but also provides a smooth and intuitive user experience during operation. The use of the buckle 112 and the slot allows the touch part 110, the buffer part 120 and the knocking part 130 to be easily aligned during assembly and maintain a stable position relationship during use. This design simplifies the assembly process, reduces production costs, and also improves the overall quality and reliability of the product.

[0047] In other embodiments, the touch portion 110 , the buffer portion 120 , and the striking portion 130 may also be connected by riveting, gluing, ultrasonic welding, or two-color injection molding.

[0048] Through riveting, gluing, ultrasonic welding or two-color injection molding and other connection methods, these parts are firmly combined together, which not only improves the mechanical strength of the product, but also ensures durability under various conditions of use. For example, riveting provides physical locking, gluing and ultrasonic welding achieve close bonding through chemical or hot melting, and two-color injection molding is formed in one step during the production process to achieve structural integration. These methods together ensure the long-term stability and durability of the product.

[0049] In this embodiment, the buffer portion 120 is made of soft material.

[0050] The buffer part 120 is made of a soft and elastic material, which is widely used in occasions where buffering is required due to its excellent shock absorption performance. The selection of soft material enables the buffer part 120 to effectively absorb and disperse the impact force when the user operates the button, thereby protecting the user's fingers from being hit by hard objects and significantly reducing the noise generated during operation. In addition, this material also has good wear resistance and aging resistance, and can maintain stable performance in long-term use, ensuring the durability and reliability of the product.

[0051] In this embodiment, the touch portion 110 is made of a hard material, and the knocking portion 130 is made of a hard material.

[0052] The touch part 110 and the knock part 130 are made of hard materials, which are selected for their high strength and good mechanical properties. The use of hard materials ensures that the touch part 110 and the knock part 130 can provide clear tactile feedback and accurate operation response when the user operates. At the same time, the hard material can also resist wear and scratches in daily use, maintaining the appearance and touch of the product. In addition, the rigidity of the hard material also provides the necessary support for the overall structure of the button, ensuring the stability and reliability of the button in various usage environments.
