Description

Technical Field

[0001] This utility model relates to the field of keyboard technology, and in particular to a silent magnetic shaft and a keyboard. Background Technology

[0002] A magnetic switch is a keyboard switch based on Hall effect technology. It triggers a signal through changes in magnetic field. Specifically, the button of a magnetic switch has a magnet. When a user presses a keycap, causing the button connected to the keycap to move downwards, the position of the magnet changes. This causes the Hall sensor on the keyboard to detect the change in magnetic field strength, which is then converted into an electrical signal to trigger a response. Through market research on magnetic switch keyboards and studying user feedback, the inventors discovered that existing magnetic switch keyboards produce a knocking sound when the button is pressed down and then bounces back up. (During the downward movement of the button, the magnet collides with the magnetic switch housing, producing a knocking sound; during the upward movement of the button, it collides with the magnetic switch housing, producing a knocking sound). This knocking sound can be very noticeable in environments such as libraries and offices, and can disturb others' work and rest. Therefore, designing and manufacturing a silent magnetic switch is the technical problem that the inventors aim to solve. Utility Model Content

[0058] First embodiment:

[0059] Reference Figures 1 to 3 This utility model provides a silent magnetic shaft, which includes a housing 100, a button 200, a magnet 300, and a spring 400.

[0060] The housing 100 includes a connected upper cover 110 and a base 120. The upper cover 110 has a clearance hole 111, through which a button 200 is slidably inserted. The button 200 is used to connect with a keycap. A first buffer 510 is fitted onto the button 200. A magnet 300 is disposed on the button 200. The base 120 has a second buffer 520. A spring 400 is disposed between the base 120 and the button 200. The first buffer 510 can be made of a soft material such as silicone; the second buffer 520 can also be made of a soft material such as silicone.

[0061] When the button 200 is pressed down, the magnet 300 can collide with the base 120 through the second buffer 520.

[0062] When the spring 400 drives the button 200 to reset and move upward, the button 200 can abut against the upper cover 110 through the first buffer 510.

[0063] Understandably, the first buffer 510 abuts against the upper cover 110, which can prevent the button 200 from moving upward away from the clearance hole 111.

[0064] In some embodiments, the first buffer 510 may be disposed on the upper cover 110, and the second buffer 520 may be disposed on the magnet 300.

[0065] With the above structure, a first buffer 510 is provided at the contact interface between the button 200 and the upper cover 110, and a second buffer 520 is provided at the contact interface between the magnet 300 and the base 120. The second buffer 520 and the first buffer 510 absorb the collision energy during the downward pressing stage and the upward rebound stage of the button 200, respectively. Therefore, the first buffer 510 and the second buffer 520 work together to effectively reduce or eliminate the collision sound energy generated by the button 200 at the end of its vertical stroke. Thus, compared with the traditional rigid collision structure of magnetic shaft, the collision sound can be greatly reduced or eliminated, thereby effectively solving the noise interference problem of magnetic shaft keyboards in scenarios such as libraries and offices.

[0066] In this embodiment, refer to Figure 2 and Figure 3 The first buffer 510 is provided with a first abutting block 511, the button 200 is provided with a first guide block 210, and the base 120 is provided with a first guide groove 121. The first guide block 210 is slidably disposed in the first guide groove 121, and the first abutting block 511 abuts against the upper side of the first guide block 210. When the spring 400 drives the button 200 to reset and move upward, the first guide block 210 can abut against and collide with the upper cover 110 through the first abutting block 511.

[0067] With the above structure, on the one hand, the first guide block 210 abuts against the upper cover 110 through the first abutting block 511, which enables the button 200 to abut against the upper cover 110 through the first buffer 510; on the other hand, the first guide block 210 and the first guide groove 121 work together to enable the button 200 to move up and down in a directional manner.

[0068] The magnet 300 is located on the button 200. The magnet 300 can abut against and collide with the base 120 through the second buffer 520. For details, please refer to [reference needed]. Figure 2 and Figure 3 The base 120 is provided with a sliding groove 122A, the button 200 is provided with a tube part S, the tube part S is slidably inserted into the sliding groove 122A, the magnet 300 is provided in the tube part S, and the bottom wall of the sliding groove 122A is provided with the aforementioned second buffer 520. When the button 200 is pressed and moved down, the magnet 300 can abut against and collide with the bottom wall of the sliding groove 122A through the second buffer 520.

[0069] In this embodiment, refer to Figure 2 The upward projection of the second buffer 520 covers the upward projection of the magnet 300.

[0070] In order to ensure that the force exerted by the second buffer 520 on the magnet 300 is located in the middle of the magnet 300 when the magnet 300 collides with the second buffer 520, thereby reducing the tilting displacement of the magnet 300 during the collision and improving the accuracy of the Hall effect sensor, refer to... Figure 2 and Figure 3 The second buffer 520 is provided with a protrusion 521 corresponding to the middle of the magnet 300, wherein when the button 200 is pressed and moved down, the magnet 300 can abut against and collide with the protrusion 521.

[0071] In some embodiments, the second buffer 520 is disposed on the magnet 300, wherein when the button 200 is pressed and moved downward, the protrusion 521 can abut against the bottom wall of the sliding groove 122A.

[0072] In some embodiments, the protrusion 521 may not be provided and the second buffer 520 may be provided in the same size as the protrusion 521, that is, the top view projection of the magnet 300 covers the top view projection of the second buffer 520, and the second buffer 520 is provided corresponding to the middle part of the magnet 300.

[0073] Second embodiment:

[0074] Reference Figures 4 to 6 This utility model provides a silent magnetic shaft, which includes a housing 100, a button 200, a magnet 300, and a spring 400.

[0075] The housing 100 includes a connected upper cover 110 and a base 120. The upper cover 110 has a clearance hole 111, and the base 120 has an extension cylinder 122. The extension cylinder 122 has a sliding groove 122A. A button 200 is slidably inserted through the clearance hole 111 and the sliding groove 122A. The button 200 is used to connect with a keycap. The button 200 has a third buffer 530, a magnet 300 is disposed in the button 200, and a spring 400 is disposed between the base 120 and the third buffer 530. The material of the third buffer 530 can be a soft material such as silicone.

[0076] When the button 200 is pressed down, it can collide with the extension cylinder 122 through the third buffer 530.

[0077] When the spring 400 drives the button 200 to reset and move upward, the button 200 can abut against the upper cover 110 through the third buffer 530.

[0078] Understandably, the third buffer 530 abuts against the top cover 110, which can prevent the button 200 from moving upward away from the clearance hole 111.

[0079] With the above structure, a third buffer 530 is provided on the button 200, so that the button 200 can flexibly contact the corresponding extension cylinder 122 or the top cover 110 through the third buffer 530, whether in the pressing down phase or the rebounding up phase. In other words, the collision energy can be absorbed in the pressing down phase and the rebounding up phase of the button 200 through the third buffer 530. Therefore, the setting of the third buffer 530 can effectively reduce or eliminate the collision sound energy generated by the button 200 at the end of the up and down stroke. Therefore, compared with the traditional magnetic axis rigid collision structure, the collision sound can be greatly reduced or eliminated, thereby effectively solving the noise interference problem of magnetic axis keyboards in scenarios such as libraries and offices.

[0080] The button component 200 includes a first up button 220 and a first down button 230.

[0081] Reference Figure 5 and Figure 6 The first upper button 220 is slidably inserted into the clearance hole 111. The first upper button 220 is used to connect with the keycap. The first upper button 220 has a tube part S. A magnet 300 is disposed in the tube part S. The tube part S is slidably inserted into the sliding groove 122A. The third buffer 530 is sleeved on the tube part S. The first lower button 230 is disposed on the first upper button 220 and together with the first upper button 220 clamps the third buffer 530.

[0082] When the button 200 is pressed down, the first upper button 220 can collide with the extension cylinder 122 through the third buffer 530.

[0083] When the spring 400 drives the button 200 to reset and move upward, the first button 230 can collide with the upper cover 110 through the third buffer 530.

[0084] In some embodiments, the spring 400 is disposed between the base 120 and the first down button 230.

[0085] In this embodiment, refer to Figure 5 and Figure 6 The third buffer 530 is provided with a second abutting block 531, the first down button 230 is provided with a second guide block 231, the base 120 is provided with a second guide groove 123, the second guide block 231 is slidably disposed in the second guide groove 123, and the second abutting block 531 abuts against the upper side of the second guide block 231. When the spring 400 drives the button 200 to reset and move upward, the second guide block 231 can abut against and collide with the upper cover 110 through the second abutting block 531.

[0086] With the above structure, on the one hand, the second guide block 231 abuts against the upper cover 110 through the second abutting block 531, which enables the button 200 to abut against the upper cover 110 through the third buffer 530; on the other hand, the second guide block 231 and the second guide groove 123 work together to enable the button 200 to move up and down in a directional manner.

[0087] To position the third buffer 530 relative to the button 200 and reduce the probability of the third buffer 530 rotating relative to the insert portion S, refer to... Figure 6 The first upper button 220 is provided with a first positioning groove 221, and the second abutting block 531 is inserted into the first positioning groove 221.

[0088] Third embodiment:

[0089] Reference Figures 7 to 9 This utility model provides a silent magnetic shaft, which includes a housing 100, a button 200, a magnet 300, and a spring 400.

The fourth buffer 540 can be made of a soft material such as silicone.

[0091] When the button 200 is pressed down, the magnet 300 can collide with the base 120 through the fourth buffer 540.

[0092] When the spring 400 drives the button 200 to reset and move upward, the button 200 can collide with the upper cover 110 through the fourth buffer 540.

[0093] Understandably, the fourth buffer 540 abuts against the top cover 110, which can prevent the button 200 from moving upward away from the clearance hole 111.

[0094] With the above structure, the magnet 300 is directly set on the fourth buffer 540. During the pressing and lowering phase and the rebounding and rising phase of the button 200, the collisions between the magnet 300 and the base 120, and between the button 200 and the top cover 110, are all absorbed by the deformation of the fourth buffer 540. In other words, the fourth buffer 540 can absorb the collision energy during the pressing and lowering phase and the rebounding and rising phase of the button 200. Therefore, the setting of the fourth buffer 540 can effectively reduce or eliminate the collision sound energy generated by the button 200 at the end of the up and down stroke. Thus, compared with the traditional rigid collision structure of magnetic axis, the collision sound can be greatly reduced or eliminated, thereby effectively solving the noise interference problem of magnetic axis keyboards in scenarios such as libraries and offices.
