Description

[0001] New type of push button switch and keyboard Technical Field

[0002] This utility model relates to the field of switch technology, and in particular to a novel push button switch and keyboard. Background Technology

[0003] A key switch is an independent component mounted on the circuit board of a mechanical keyboard. Each key press activates an individual key switch. Keyboard key switches are crucial components; their specific structure and performance stability determine the keyboard's lifespan and the comfort of the typing experience.

[0004] In existing technology, push-button switches generally include a top cover, a handle, a magnetic post, a spring, and a base. The magnetic post is usually housed within the handle and is roughly integrated with it, moving with the handle's movement. In some cases, touching or shaking the handle will cause the magnetic post to shake simultaneously, affecting the change in magnetic flux and potentially impacting the button's output. Furthermore, during the pressing process, the magnetic post produces sound. Since the material of the magnetic post is fixed, the sound effect is also fixed, making it difficult to create diverse audio experiences. However, in some applications, different button impact sounds can provide a better user experience, especially during gaming, where choosing a better impact sound can enhance immersion and improve the overall experience.

[0005] Therefore, it is necessary to provide a new type of push button switch with a more stable overall structure that will not directly shake the magnetic column when the push handle is shaken, and which can select various impact sound effects. Utility Model Content

[0006] The purpose of this invention is to provide a new type of button switch with a more stable overall structure that will not directly shake the magnetic column due to shaking of the handle, and which can select various impact sound effects.

[0007] Another objective of this invention is to provide a keyboard in which key movement does not affect keyboard output and various impact sound effects can be selected.

[0008] To achieve the above objectives, this utility model provides a novel push-button switch, comprising:

[0009] The top cover has a through-hole opening for the first cavity;

[0010] The base is connected to the top cover and has a second cavity, which together with the first cavity form a receiving cavity.

[0011] The handle is installed in the receiving cavity and one end protrudes out of the first cavity for pressing, and has a hollow inner cavity.

[0012] The shaft core assembly has one end installed in the inner cavity and the other end protruding out of the inner cavity and elastically movable in the base by means of an elastic element. The elastic element is sleeved on the shaft core assembly and one end of the elastic element abuts against the shaft core assembly, while the other end abuts against the base.

[0013] Magnetic column, located within the shaft core assembly;

[0014] A rolling element is provided between the shaft core assembly and the button, which allows the shaft core assembly and the button to rotate freely at multiple angles.

[0015] With the above technical solution, the novel push button switch of this utility model includes a top cover, a base, a handle, a shaft core assembly, a magnetic post, a rolling element, and an elastic element. The top cover has a first cavity extending through it. The base is connected to the top cover, and a second cavity is formed within the base, which, together with the first cavity, forms a receiving cavity for accommodating the handle. The handle is installed within the receiving cavity, with one end protruding from the first cavity for pressing. A hollow inner cavity is formed within the handle for installing the shaft core assembly. The shaft core assembly is installed within the inner cavity, with one end protruding from the inner cavity, and is elastically mounted within the base by the elastic element. The magnetic post is disposed within the shaft core assembly. A rolling element is provided between the shaft core assembly and the handle, allowing the shaft core assembly and the handle to rotate freely at multiple angles. It is understood that the magnetic post is not directly connected to the handle; shaking the handle will not directly shake the magnetic post, thus minimizing its impact. Furthermore, a rolling element is provided between the button and the shaft core assembly. Shaking the button directly acts on this rolling element, which rotates freely at multiple angles between the button and the shaft core assembly, acting like a universal bearing. This ensures that the shaking of the button acts on the rolling element, preventing it from causing the shaft core assembly and its internal magnetic pillar to shake. This minimizes the impact on the magnetic pillar and makes the overall structure more stable and reliable. On the other hand, pressing the button directly moves the shaft core assembly and its internal magnetic pillar downwards. The bottom of the shaft core assembly, which encloses the magnetic pillar, contacts the base. The shaft core assembly can be replaced with various suitable materials according to the actual sound effect requirements. This novel push-button switch has a more stable overall structure, preventing the magnetic pillar from shaking due to button shaking, and allows for selection of various impact sound effects.

[0016] Preferably, the shaft assembly includes an upper shaft and a lower shaft, which are detachably connected.

[0017] Preferably, the upper shaft core is provided with a mounting groove for accommodating the rolling element at the end away from the lower shaft core. The rolling element is installed in the mounting groove and one end protrudes out of the mounting groove to make rolling contact with the handle.

[0018] Preferably, the mounting groove has a spherical structure that mates with the rolling element, allowing the rolling element to be mounted in the mounting groove at multiple angles.

[0019] Preferably, the mounting groove is provided with multiple limiting blocks protruding along its periphery. The multiple limiting blocks are evenly distributed on the periphery of the mounting groove to cover the rolling element. Each limiting block can move elastically within a preset range to allow the rolling element to be installed into the mounting groove.

[0020] Preferably, the surface of each limiting block facing the rolling element is an arc-shaped surface that mates with the rolling element, and the rolling element is installed in the mounting groove and rolls against the arc-shaped surface.

[0021] Preferably, the inner cavity of the handle is provided with an arc-shaped groove that mates with the rolling element, and one end of the rolling element protruding from the upper shaft is rotatably disposed in the arc-shaped groove.

[0022] Preferably, the upper shaft core has a first groove and the lower shaft core has a second groove, the first groove and the second groove forming a mounting cavity for accommodating the magnetic post.

[0023] Preferably, the base has a mounting part that mates with the elastic element. One end of the elastic element is fitted onto the mounting part and abuts against the base, while the other end of the elastic element is fitted onto the shaft core assembly and abuts against the shaft core. Pressing the handle moves the shaft core assembly downward and compresses the elastic element. The compressed elastic element always tends to drive the shaft core assembly and the handle to reset.

[0024] To achieve the other objective mentioned above, the present invention also provides a keyboard, including a keyboard body and the aforementioned novel key switches, wherein a plurality of novel key switches are movably mounted on the keyboard body.

[0025] After adopting the above technical solution, the keyboard of this utility model will not affect the keyboard output when the keys are shaken, the overall output effect is better, the structure is more stable, and various impact sound effects can be selected, providing more choices for the user experience and a better overall experience.

[0042] To explain the technical content and structural features of this utility model in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0043] Please see Figures 1 to 4 and Figure 6This utility model provides a novel push-button switch 100, including a top cover 10, a base 20, a push handle 30, a shaft core assembly 40, a magnetic post 50, and a rolling element 60. The top cover 10 has a through-hole first cavity 101 and a first engaging portion 11 that engages with the base 20. The base 20 has a second cavity 201 and a second engaging portion 21, which connects to the first engaging portion 11 of the top cover 10, so that the second cavity 201 and the first cavity 101 engage to form a receiving cavity 110, which is used to install the push handle 30. The push handle 30 is installed in the receiving cavity 110, with one end protruding from the first cavity 101 for pressing. A hollow inner cavity 301 is formed within the push handle 30 for installing the shaft core assembly 40. One end of the shaft core assembly 40 is installed in the inner cavity 301, and the other end protrudes from the inner cavity 301 and is elastically movably disposed in the base 20 by means of an elastic member 70. The elastic member 70 is sleeved on the shaft core assembly 40, with one end of the elastic member 70 abutting against the shaft core assembly 40 and the other end abutting against the base 20. The magnetic post 50 is disposed inside the shaft core assembly 40. Specifically, a rolling member 60 is provided between the shaft core assembly 40 and the handle 30, so that the shaft core assembly 40 and the handle 30 can rotate freely at multiple angles, and the multi-angle shaking of the handle 30 directly acts on the rolling member 60, greatly reducing the impact on the shaft core assembly 40.

[0044] With the above technical solution, the novel push button switch 100 of this utility model includes a top cover 10, a base 20, a push handle 30, a shaft core assembly 40, a magnetic post 50, a rolling element 60, and an elastic element 70. The top cover 10 has a first cavity 101 extending through it. The base 20 is connected to the top cover 10. A second cavity 201 is formed within the base 20, and the second cavity 201 cooperates with the first cavity 101 to form a receiving cavity 110 for accommodating the push handle 30. The push handle 30 is installed in the receiving cavity 110, with one end protruding from the first cavity 101 for pressing. A hollow inner cavity 301 is formed within the push handle 30 for installing the shaft core assembly 40. The shaft core assembly 40 is installed in the inner cavity 301, with one end protruding from the inner cavity 301, and is elastically and movably installed within the base 20 by means of the elastic element 70. The magnetic post 50 is disposed within the shaft core assembly 40. A rolling element 60 is provided between the shaft core assembly 40 and the handle 30, allowing the shaft core assembly 40 and the handle 30 to rotate freely at multiple angles. Understandably, the magnetic column 50 is not directly connected to the handle 30; shaking the handle 30 will not directly shake the magnetic column 50, thus minimizing its impact. Furthermore, the rolling element 60 between the handle 30 and the shaft core assembly 40 directly acts on the handle 60 when the handle 30 is shaken. The rolling element 60 rotates freely at multiple angles between the handle 30 and the shaft core assembly 40, acting like a universal bearing. This ensures that the shaking of the handle acts on the rolling element 60, and the rotation of the rolling element 60 does not cause the shaft core assembly 40 or its internal magnetic column 50 to shake, further minimizing the impact on the magnetic column 50 and making the overall structure more stable and reliable. On the other hand, when the button 30 is pressed, it directly drives the shaft core assembly 40 and the magnetic column 50 inside it to move downwards. The bottom of the shaft core assembly 40, which encloses the magnetic column 50, contacts the base 20. The shaft core assembly 40 can be replaced with various suitable materials according to the actual sound effect requirements. The overall structure of the novel button switch 100 of this utility model is more stable, and the magnetic column 50 will not shake directly due to shaking the button 30. It can also select various impact sound effects.

[0045] Please see Figure 1 , Figure 2 and Figure 6 In some optional embodiments, the shaft core assembly 40 includes an upper shaft core 41 and a lower shaft core 42, which are detachably connected. The upper shaft core 41 can engage with the lower shaft core 42 to form a single structure. In other embodiments, the shaft core assembly 40 can enclose the magnetic post 50 and be molded into a single structure, resulting in a more robust overall structure.

[0046] Please see Figure 6 and Figure 7In some optional embodiments, the end of the upper shaft core 41 away from the lower shaft core 42 is provided with a mounting groove 411 for accommodating the rolling element 60. The rolling element 60 is spherical, and the mounting groove 411 is hemispherical. For example, the rolling element 60 can be a steel ball, other metal spheres, or ceramic beads, etc. The rolling element 60 is installed in the mounting groove 411 and one end protrudes out of the mounting groove 411 to roll in contact with the handle 30. Specifically, the mounting groove 411 has a spherical structure that mates with the rolling element 60, and the rolling element 60 is rotatably installed in the mounting groove 411 at multiple angles. On the other hand, the inner cavity 301 of the handle 30 is provided with an arc-shaped groove 31 that mates with the rolling element 60, and the end of the rolling element 60 protruding out of the upper shaft core 41 is rotatably disposed in the arc-shaped groove 31. Understandably, one end of the handle 30 protrudes from the upper cover 10. When the handle 30 is shaken, the arc groove 31 inside the handle 30 acts on the rolling element 60, causing the rolling element 60 to roll at multiple angles within the mounting groove 411 and the arc groove 31. The force of the handle 30 shaking acts on the rolling element 60 and does not directly act on the shaft core assembly 40. At this time, the rolling element 60 is equivalent to a universal bearing, rotating at multiple angles between the handle 30 and the shaft core assembly 40.

[0047] Please see Figure 6 and Figure 7 In some optional embodiments, a plurality of limiting blocks 412 are provided protruding along the periphery of the mounting groove 411, and the plurality of limiting blocks 412 are evenly distributed on the periphery of the mounting groove 411 to cover the rolling element 60. The limiting blocks 412 protrude from the mounting groove 411 and can limit the rolling element 60, so that the rolling element 60 is more securely installed in the mounting groove 411. Each limiting block 412 can elastically move within a preset range to allow the rolling element 60 to be inserted into the mounting groove 411. It can be understood that the plurality of limiting blocks 412 are arranged in a lotus shape on the outer ring of the mounting groove 411, and the rolling element 60 in the mounting groove 411 is in a semi-enclosed state. During installation, the rolling element 60 can be pressed through the plurality of limiting blocks 412 with a little force, and then the rolling element 60 is installed in the mounting groove 411. During the pressing of the rolling element 60, the limiting block 412 will move elastically backward within a certain range to enlarge the installation opening, thereby allowing the rolling element 60 to be installed into the installation groove 411. Then the limiting block 412 elastically resets and wraps around the rolling element 60. The structure is simple, the installation effect of the rolling element 60 is better, and the overall structure is more stable and reliable.

[0048] Please see Figure 6 and Figure 7In some optional embodiments, the surface of each limiting block 412 facing the rolling element 60 is an arc-shaped surface 4121 that mates with the rolling element 60. The rolling element 60 is installed in the mounting groove 411 and rolls against the arc-shaped surface 4121. It can be understood that the arc-shaped surface 4121 of the limiting block 412 mates with the rolling element 60 allows for better rolling contact with the rolling element 60, enabling the rolling element 60 to roll more smoothly when the handle 30 is shaken, thereby better reducing the impact on the shaft core assembly 40.

[0049] Please see Figure 2 and Figures 6 to 8 In some optional embodiments, the upper shaft core 41 has a first groove 414, and the lower shaft core 42 has a second groove 421. The first groove 414 and the second groove 421 form a mounting cavity for accommodating the magnetic post 50. The upper shaft core 41 and the lower shaft core 42 are detachably connected. The magnetic post 50 is installed in the first groove 414 and the second groove 421, and the upper shaft core 41 and the lower shaft core 42 are fastened together, so that the magnetic post 50 is located within the shaft core assembly 40. This can further reduce the impact of the shaking handle on the magnetic post 50, and the sound of the lower shaft core 42 hitting the bottom cover during pressing can be changed by changing the material of the lower shaft core 42.

[0050] Please see Figure 1 and Figure 2 In some optional embodiments, a mounting portion 22 that mates with the elastic member 70 is protruding from the base 20. One end of the elastic member 70 is sleeved on the mounting portion 22 and abuts against the base 20. The elastic member 70 is sleeved on the shaft core assembly 40 and the other end abuts against the upper shaft core 41. Pressing the handle 30 moves the shaft core assembly 40 downward and compresses the elastic member 70. The compressed elastic member 70 always has a tendency to drive the shaft core assembly 40 and the handle 30 to reset. Specifically, a positioning portion 413 for positioning the elastic member 70 is protruding circumferentially from the end of the upper shaft core 41 away from the lower shaft core 42. One end of the elastic member 70 abuts against the positioning portion 413, making the overall structure stable and reliable. On the other hand, the mounting part 22 is hollow, the shaft core assembly 40 is elastically slidably disposed inside the mounting part 22, and the elastic member 70 is sleeved outside the mounting part 22. The mounting part 22 can guide the movement of the shaft core assembly 40 to prevent displacement from affecting the overall structure and output effect.

[0051] To achieve the aforementioned other objective, the present invention also provides a keyboard, including a keyboard body and the aforementioned novel key switches 100, wherein multiple novel key switches 100 are movably mounted on the keyboard body. By adopting the above technical solution, the keyboard of this invention does not affect the keyboard output when the keys are shaken, resulting in better overall output performance, a more stable structure, and the ability to select various impact sound effects, providing more choices and a better user experience.

[0052] like Figures 1 to 8 As shown, the keyboard of this utility model includes multiple novel key switches 100. Each novel key switch 100 includes a top cover 10, a base 20, a key handle 30, a core assembly 40, a magnetic post 50, a rolling element 60, and an elastic element 70. The top cover 10 has a through-hole first cavity 101. The base 20 is connected to the top cover 10. The base 20 has a second cavity 201, which cooperates with the first cavity 101 to form a receiving cavity 110 for accommodating the key handle 30. The key handle 30 is installed in the receiving cavity 110, with one end protruding from the first cavity 101 for pressing. The key handle 30 has a hollow inner cavity 301 for installing the core assembly 40. The core assembly 40 is installed in the inner cavity 301, with one end protruding from the inner cavity 301, and is elastically and movably mounted in the base 20 by the elastic element 70. The magnetic post 50 is disposed within the core assembly 40. A rolling element 60 is provided between the shaft core assembly 40 and the handle 30, allowing the shaft core assembly 40 and the handle 30 to rotate freely at multiple angles. Understandably, the magnetic column 50 is not directly connected to the handle 30; shaking the handle 30 will not directly shake the magnetic column 50, thus minimizing its impact. Furthermore, the rolling element 60 between the handle 30 and the shaft core assembly 40 directly acts on the handle 60 when the handle 30 is shaken. The rolling element 60 rotates freely at multiple angles between the handle 30 and the shaft core assembly 40, acting like a universal bearing. This ensures that the shaking of the handle acts on the rolling element 60, and the rotation of the rolling element 60 does not cause the shaft core assembly 40 or its internal magnetic column 50 to shake, further minimizing the impact on the magnetic column 50 and making the overall structure more stable and reliable. On the other hand, when the handle 30 is pressed, it directly drives the shaft core assembly 40 and its internal magnetic column 50 downwards. The lower shaft core 42 contacts the base 20. The lower shaft core 42 can be replaced with various suitable materials according to the actual sound effect requirements. The overall structure of the novel button switch 100 of this utility model is more stable. It will not directly shake the magnetic column 50 due to shaking the handle 30, and it can select various impact sound effects, providing more choices and a better user experience.
