[0002] The key switch commonly used in mechanical keyboards is the Hall induction key switch. The magnet is installed on the core shaft, and the Hall element is coaxial with the magnet and is arranged below the magnet. The core shaft moves up and down to drive the magnet to move, thereby triggering the Hall element to turn the key switch on or off.

[0003] Conventional key switches are usually installed on the keyboard circuit board and are always connected to the keyboard circuit board. This method on a wireless keyboard will result in high power consumption of the wireless keyboard, which often needs to be charged, which is not conducive to people's daily use. In addition, general key switches do not have a silent effect. If the silent function is required, it is necessary to set silent pads at the upper and lower ends of the guide core respectively, so as to buffer and silence the impact force of the guide core hitting the inner wall of the cavity. This method results in a large number of complex structures in the key switch, and the maintenance cost is also relatively high, which is not conducive to use. Utility Model Content

[0004] In view of the above-mentioned deficiencies, the purpose of the utility model is to provide a magnetic axis with a wake-up function, which is arranged inside to trigger a mechanical switch when pressed by the user, thereby waking up the Hall element to realize signal transmission.

It also has a silent arm to buffer the downward impact, thereby realizing the silent function, and its structure is simple, which is conducive to production and use.

[0005] The technical solution adopted by the utility model to achieve the above-mentioned purpose is:

[0006] A magnetic axis with a wake-up function comprises a base, an upper cover covering the base, a guide core arranged inside the base and the upper cover and extending upward through the upper cover, a return spring with its upper end pressed against the guide core and its lower end pressed against the base, a permanent magnet arranged at the lower end of the guide core, and a Hall element, and also comprises a moving piece arranged on the side of the guide core, and a static piece arranged below the moving piece; at least one convex ridge is formed on the side of the guide core, the moving piece comprises at least one moving piece support arm extending laterally in the direction of the convex ridge, the moving piece support arm is driven by the convex ridge to achieve contact or separation with the static piece under the action of external force pressing the guide core, and realizes the control of the conduction and disconnection of the Hall element, so as to correspondingly wake up or sleep the Hall element, and the Hall element senses the descending permanent magnet after being awakened; the moving piece and the static piece are respectively electrically connected to an external circuit board, and the moving piece and the static piece are stacked up and down.

[0007] As a further improvement of the utility model, the movable piece also includes a movable piece body and at least one movable piece pin integrally formed on the movable piece body, the movable piece support arm is arranged on the movable piece body, and the movable piece pin is electrically connected to the external circuit board.

[0008] As a further improvement of the present invention, the static piece includes a static piece body located below the moving piece body, at least one static piece support arm arranged on the static piece body and extending laterally in the direction of the convex ridge, and at least one static piece pin integrally formed on the static piece body, the static piece pin is electrically connected to an external circuit board, and the moving piece support arm is driven by the convex ridge to achieve contact or separation with the static piece support arm under the action of external force pressing the guide core.

[0009] As a further improvement of the utility model, at least one static piece giving way groove is formed on the static piece body to give way to the movable piece pin.

[0010] As a further improvement of the present invention, the number of the moving piece support arms, the number of the static piece support arms and the number of the convex ridges correspond one to one.

[0011] As a further improvement of the utility model, at least one mute arm that can be elastically bent and reset is formed at the middle and lower end of the guide core respectively, and a buffer space for the mute arm to move is formed between the mute arm and the guide core.

[0012] As a further improvement of the utility model, a silent buffer platform protruding outward is formed on the outermost side of the silent arm.

[0013] As a further improvement of the present invention, the static piece pin includes a first static piece pin that is bent downward and extends from the static piece body, and a second static piece pin that is arranged on the side of the lower end of the first static piece pin and extends downward after being bent toward the guide core direction, and the second static piece pin gives way to a mute arm arranged at the lower end of the guide core.

[0014] The beneficial effects of the utility model are:

[0015] The shaft structure is configured to include a base that can be installed on a keyboard, an upper cover covering the base, a guide core arranged in the base and the upper cover and extending upward through the upper cover, a return spring whose upper end presses against the guide core and whose lower end presses against the base, a permanent magnet arranged in the lower part of the guide core, and a Hall element arranged on an external circuit board and facing the permanent magnet.

When the external force is separated from the guide core, the guide core moves the convex ridges and permanent magnets thereon upward and resets under the drive of the reset spring, and the convex ridges lift the outermost side of the movable arm, thereby separating the movable arm from the static plate, disconnecting the circuit between the movable plate and the static plate, and the Hall element on the external circuit board is dormant and non-conductive without receiving the start signal, thereby realizing the purpose of saving power and reducing power consumption, increasing the use time of the wireless keyboard, and facilitating people's use; by stacking the movable plate and the static plate in parallel with each other, the travel of the movable plate and the static plate can be very short, thereby realizing the awakening of the Hall element before the Hall element senses the permanent magnet signal, and ensuring the timely and accurate signal transmission.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality" means two or more, unless otherwise specifically defined.

[0031] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] Please refer to Figures 1 to 9 The utility model provides a magnetic axis with a wake-up function, including a base 1 that can be installed on a keyboard, an upper cover 2 covering the base 1, a guide core 3 arranged in the base 1 and the upper cover 2 and extending upward through the upper cover 2, a return spring with an upper end pressed against the guide core 3 and a lower end pressed against the base 1, a permanent magnet 4 arranged in the lower part of the guide core 3, a Hall element 5 arranged on an external circuit board 8 and facing the permanent magnet 4, and also including a moving piece 6 arranged on the side of the guide core 3 and elastically bent downward as a whole, and a static piece 7 arranged below the moving piece 6; at least one convex rib 31 is formed on the side of the guide core 3, and the moving piece includes at least one moving piece support arm 61 extending laterally in the direction of the convex rib 31, and the moving piece support arm 61 is driven by the convex rib 31 under the action of external force pressing the guide core 3 to achieve contact or separation with the static piece 7, and the moving piece 6 and the static piece 7 are respectively electrically connected to the circuit board 8 on the external wireless keyboard.

[0033] When the external force presses the guide core 3, the guide core 3 drives the convex rib 31 and the permanent magnet 4 thereon to move downward, so that the movable arm 61 whose lower end face is pressed against the convex rib 31 is pressed downward against the static plate 7 under the action of its own elastic restoring force, thereby realizing the closure of the circuit, transmitting the start signal to the external circuit board 8 to wake up the Hall element 5, and the Hall element 5 senses the descending permanent magnet 4, thereby transmitting the operation signal. When the external force is separated from the guide core 3, the guide core 3 is driven by the reset spring to move the convex rib 31 and the permanent magnet 4 thereon upward and reset, and the convex rib 31 lifts the outermost side of the movable arm 61, thereby separating the movable arm 61 from the static plate, disconnecting the circuit between the movable plate 6 and the static plate 7, and the Hall element 5 on the external circuit board 8 is dormant and non-conductive without receiving the start signal, thereby realizing the purpose of saving power and reducing power consumption, and increasing the use time of the wireless keyboard, which is convenient for people to use. By stacking the moving piece 6 and the static piece 7 in parallel, the travel of the moving piece 6 and the static piece 7 can be very short, so that the Hall element 5 can be awakened before the Hall element 5 senses the signal of the permanent magnet 4, ensuring timely and accurate signal transmission.

[0034] Regarding the specific structural arrangement of the moving piece 6, as shown in FIG. Figures 2 to 5As shown in the figure, the movable piece 6 further includes a movable piece body 62, and at least one movable piece pin 63 disposed on the movable piece body 62 and bent downward and extending. The movable piece support arm 61 is disposed on the movable piece body 62, and the movable piece pin 63 is electrically connected to an external circuit board 8. The movable piece pin 63 is embedded in the circuit board 8 of the wireless keyboard, so as to realize the electrical connection between the movable piece and the wireless keyboard circuit, realize the transmission of the start signal, wake up the Hall element 5 disposed on the wireless keyboard circuit board 8, and the Hall element 5 senses the permanent magnet 4 to realize the transmission of the operation signal. One end of the movable piece body 62 away from the guide core 3 abuts against the base 1, so as to fix the position of the movable piece 6, and prevent the problem that the movable piece body 62 cannot be separated from the static piece 7 when the guide core 3 moves upward driven by the movable piece support arm 61 and moves downward.

[0035] Regarding the specific structural setting of the static piece 7, as Figures 2 to 6 shown, the static piece 7 includes a static piece body 71 located below the movable piece body 62, at least one static piece support arm 72 disposed on the static piece body 71 and extending horizontally in the direction of the convex rib 31, and at least one static piece pin 73 disposed on the static piece body 71 and bent downward as a whole and extending. The static piece pin 73 is electrically connected to the external circuit board 8. Specifically, the static piece pin 73 is embedded in the circuit board 8 of the wireless keyboard, so as to realize the electrical connection between the static piece 7 and the wireless keyboard circuit, realize the transmission of the start signal, wake up the Hall element 5 disposed on the wireless keyboard circuit board 8, and the Hall element 5 senses the permanent magnet 4 to realize the transmission of the operation signal. The movable piece support arm 61 is driven by the convex rib 31 under the action of an external force pressing the guide core 3 to contact or separate from the static piece support arm 72. Specifically, when the external presses the guide core 3, the guide core 3 drives the convex rib 31 thereon to move downward, so that the movable piece support arm 61 with its lower end surface abutting against the convex rib 31 contacts the static piece support arm 72 downward under its own elastic restoring force, thereby realizing the closing of the loop, and the static piece pin 73 and the movable piece pin 63 are embedded on the external circuit board 8, so as to transmit the start signal to the circuit board 8 on the wireless keyboard or directly to the Hall element 5, thereby waking up the Hall element 5 and realizing the transmission of the operation signal. When the external force is removed from the guide core 3, the guide core 3 drives the convex rib 31 thereon to move upward and reset under the drive of the return spring, and the band-pass step lifts the outermost side of the movable piece support arm 61, so that the movable piece support arm 61 is separated from the static piece support arm 72, and the loop between the movable piece and the static piece is disconnected. The Hall element 5 sleeps and is not conducting without receiving the start signal, so as to achieve the purpose of saving power, reducing power consumption, increasing the usage time of the wireless keyboard, and facilitating people's use. One end of the static piece body 71 away from the guide core 3 abuts against the base 1, so as to fix the position of the static piece 7, prevent the situation that the static piece body 71 is displaced during operation, resulting in the movable piece support arm 61 not being able to conduct normally with the static piece support arm 72, and improve the conduction accuracy and efficiency of this structure.

[0036] Preferably, in order to improve the space utilization rate inside the shaft body, such as Figures 2 to 4 and Figure 6 As shown, at least one static sheet relief groove 74 for giving way to the moving sheet pin 63 is formed on the static sheet body 71. By providing the static sheet relief groove 74 to give way to the moving sheet pin 63, the occupied space of the moving sheet and the static sheet inside the shaft body is smaller, the space utilization rate inside the shaft body is improved, the shaft body structure is made lighter and more convenient for use.

[0037] In order to prevent the situation where the guide core 3 cannot drive the moving sheet support arm 61 normally when different positions of the guide core 3 are pressed by external force, such as Figures 2 to 6 As shown, the number of the moving sheet support arms 61 is 3 groups, the number of the static sheet support arms 72 is 3 groups corresponding one-to-one to the moving sheet support arms 61, and the number of the convex ribs 31 is also 3 groups corresponding one-to-one to the moving sheet support arms 61. The moving sheet support arms 61 are respectively the first group of moving sheet support arms 61 arranged on the side of the guide core 3, the second group of moving sheet support arms 61 arranged in the middle of the guide core 3, and the third group of moving sheet support arms 61 arranged on the other side of the guide core 3. Thus, no matter which position of the guide core 3 is pressed by external force, the convex ribs 31 on the guide core 3 can drive the moving sheet support arms 61 to contact or separate from the static sheet support arms 72.

[0038] Preferably, as Figures 2 to 5 shown, two groups of moving sheet support arms 61 arranged on the side are respectively provided with a moving sheet extension plate 611 extending laterally towards the convex rib 31, which is beneficial for the convex rib 31 to drive the two groups of moving sheet support arms 61 arranged on the side through the moving sheet extension plate 611. Furthermore, the moving sheet support arms 61 are driven by the convex rib 31 under the action of external force pressing the guide core 3 to contact or separate from the static sheet support arms 72, improving the efficiency and accuracy of the guide core 3 driving the moving sheet support arms 61 and being beneficial for the cooperation between components.

[0039] Preferably, as Figures 3 to 4 and Figure 6 shown, two groups of static sheet support arms 72 arranged on the side are respectively provided with a static sheet extension plate 721 extending laterally towards the convex rib 31 and facing the moving sheet extension plate 611, which is beneficial for the moving sheet extension plate 611 to correspondingly abut against the static sheet extension plate 721, thereby realizing the conduction between the moving sheet and the static sheet and being beneficial for the cooperation between components.

[0040] Preferably, as Figure 7As shown, in order to better drive the moving piece arm 61 by the convex rib 31, a first driving guiding inclined surface 311 extending obliquely from the inner upper direction to the outer lower direction is formed at the upper end of the convex rib 31. When the external force is removed from the guide core 3, the guide core 3 is driven by the reset spring in the shaft body to move the convex rib 31 thereon upward for reset. The first driving guiding inclined surface 311 on the band-pass step first contacts the moving piece arm 61, so that the moving piece arm 61 fits with the convex rib 31 under the inclined guiding action of the first driving guiding inclined surface 311, enabling the convex rib 31 to better drive the moving piece arm 61, improving the efficiency and accuracy of the guide core 3 driving the moving piece arm 61, and facilitating the cooperation between components.

[0041] Regarding whether the moving piece arm 61 is fixedly abutted against the convex rib 31, or when the guide core 3 is pressed, it bends downward under the action of its own elastic restoring force and disengages from the convex rib 31, and then is driven by the convex rib 31 again when the guide core 3 moves upward, or the moving piece arm 61 is horizontally arranged, and the convex rib 31 presses down and bends the moving piece arm 61 during the downward pressing process so that the moving piece arm 61 contacts the static piece arm 72, and when the convex rib 31 moves upward, the moving piece arm 61 returns to the horizontal setting under its own elastic restoring force and separates from the static piece arm 72, or other ways to realize the driving of the moving piece arm 61 by the convex rib 31 to achieve contact or separation with the static piece arm 72 are all acceptable, and it can be set according to the actual situation, so no specific limitation is made in this embodiment.

[0042] Preferably, as Figure 7 shown, if the moving piece arm 61 is horizontally arranged, and the convex rib 31 presses down and bends the moving piece arm 61 during the downward pressing process so that the moving piece arm 61 contacts the static piece arm 72, and when the convex rib 31 moves upward, the moving piece arm 61 returns to the horizontal setting under its own elastic restoring force and separates from the static piece arm 72, a second driving guiding inclined surface 312 extending obliquely from the outer upper direction to the inner lower direction can be formed at the lower end of the convex rib 31. When the external force presses the guide core 3 downward, the second driving guiding inclined surface 312 first contacts the moving piece arm 61, and the moving piece arm 61 fits more closely with the convex rib 31 under the inclined guiding action of the second driving guiding inclined surface 312, and is thus pressed downward by the convex rib 31 until it contacts and conducts with the static piece arm 72, improving the efficiency and accuracy of the guide core 3 driving the moving piece arm 61, and facilitating the cooperation between components.

[0043] In order to make the shaft body structure have a silent effect, as Figure 9As shown, at least one silent arm 32 that can be elastically bent and reset is formed at the middle and lower ends of the guide core 3 respectively. A buffer space 33 for the movement of the silent arm 32 is formed between the silent arm 32 and the guide core 3. When the guide core 3 moves downward, the silent arm 32 arranged at the lower end of the guide core 3 first contacts the inner wall of the base 1. The silent arm 32 arranged at the lower end of the guide core 3 bends into the buffer space 33 under the downward impact force, thereby buffering the impact force and reducing the noise generated by the guide core 3 hitting the base 1, so as to achieve the purpose of noise reduction and improve the user's experience. When the guide core 3 is driven by the return spring to move upward and reset, the silent arm 32 arranged at the middle position of the guide core 3 first contacts the inner wall of the upper cover 2. The silent arm 32 arranged at the middle position of the guide core 3 bends into the buffer space 33 under the upward impact force, thereby buffering the impact force and reducing the noise generated by the guide core hitting the upper cover 2, so as to achieve the purpose of noise reduction and further improve the user's experience.

[0044] Preferably, as Figure 9 shown, there are 4 groups of the silent arms 32, which are respectively arranged on both sides of the lower end of the guide core 3 and on both sides near the middle of the upper end of the guide core 3, so that the buffering force on the guide core 3 is more uniform, and the noise reduction effect of the shaft body structure is further improved.

[0045] In order to make the silent arm 32 better buffer the downward impact force, as Figure 9 shown, a silent buffer platform 34 that is integrally trapezoidal and protrudes outward is formed on the outermost side of the silent arm 32. When the guide core 3 moves downward, the silent buffer platform 34 first contacts the inner wall of the base 1. The silent buffer platform 34 drives the silent arm 32 to bend into the buffer space 33, thereby buffering the impact force and reducing the noise generated by the guide core 3 hitting the base 1, so as to achieve the purpose of noise reduction and improve the user's experience. When the guide core 3 is driven by the return spring to move upward and reset, the silent buffer platform 34 first contacts the inner wall of the upper cover 2. The silent buffer platform 34 drives the silent arm 32 to bend into the buffer space 33, thereby buffering the impact force and reducing the noise generated by the guide core 3 hitting the upper cover 2, so as to achieve the purpose of noise reduction and further improve the user's experience.

[0046] Preferably, as Figure 3 and Figure 9As shown, in order to further improve the space utilization rate inside the shaft body, the static blade pin 73 includes a first static blade pin 731 that extends downward and bends from the static blade body 71, and a second static blade pin 732 that is arranged on the lower side edge of the first static blade pin 731, bends toward the direction of the guide core 3 and then extends downward. The second static blade pin 732 gives way to the mute arm 32. By arranging the second static blade pin 732 to bend as a whole toward the direction of the guide core 3, it gives way to the mute arm 32 arranged at the lower end position of the guide core and other structures inside the base 1, which is beneficial to the cooperation between various components. As a result, the occupied space of the static blade and the guide core 3 inside the shaft body structure is smaller, the space utilization rate of the shaft body structure is improved, the shaft body structure is made lighter, and it is beneficial to production and use.
