[0029] Please refer to Figures 1 to 6, the utility model embodiment provides a kind of wake-up conduction structure for key switch, including a guide core 1, the dynamic sheet 2 being located on the side of guide core 1 and being bent down elastically as a whole, and the static sheet 3 being arranged below the dynamic sheet 2, at least one convex ridge 11 is formed on the side of guide core 1, the dynamic sheet 2 includes at least one dynamic sheet arm 21 extending transversely to the direction of convex ridge 11, the dynamic sheet arm 21 is driven to realize contact or separation with static sheet 3 under the action of the convex ridge 11 under the action of external force pressing guide core 1, the dynamic sheet 2 and static sheet 3 are electrically connected with external circuit respectively, the dynamic sheet 2 and static sheet 3 are mutually parallel and stacked up and down.The wake-up conduction structure can be installed on different types of shaft bodies such as Hall shaft body, optical shaft, etc., thereby as the wake-up structure of different types of shaft bodies, its applicable range is large, more practical.

[0030] Its specific operation mode is that when external force presses guide core 1, the guide core 1 drives the convex ridge 11 on it to move down, so that the lower end surface is pressed on the dynamic sheet arm 21 on the convex ridge 11, which is pressed on the static sheet 3 under the action of its elastic restoring force, thereby realizing the closure of the loop, and transmitting the start signal to the conduction component of the external circuit board or Hall element or light-emitting diode, etc., to wake up the conduction component on the shaft body, thereby realizing the transmission of operation signal.When external force is removed from guide core 1, the guide core 1 is driven by the reset spring in the shaft body to move up and reset the convex ridge 11 on it, the convex ridge 11 lifts the outermost side of the dynamic sheet arm 21, thereby separating the dynamic sheet arm 21 from the static sheet 3, and the loop between the dynamic sheet 2 and the static sheet 3 is disconnected, and the conduction component of the external circuit board or Hall element or light-emitting diode, etc., is in a dormant state without conduction under the condition of not receiving the start signal, thereby realizing the purpose of saving power and reducing power consumption, improving the use time of wireless keyboard, and facilitating people to use.By stacking the dynamic sheet 2 and the static sheet 3 mutually parallel and up and down, the stroke of the dynamic sheet 2 and the static sheet 3 can be very short, thereby realizing the wake-up of the conduction component of the Hall element or light-emitting diode, etc., before sensing other structures or starting, to ensure the timely and accurate signal transmission.

[0031] For the specific structure of the dynamic sheet 2, as shown in Figures 1 to 4, the dynamic sheet 2 further includes a dynamic sheet body 22 and at least one dynamic sheet pin 23 arranged on the dynamic sheet body 22 and extending downward, the dynamic sheet arm 21 is arranged on the dynamic sheet body 22, and the dynamic sheet pin 23 is electrically connected with the external circuit, specifically, the dynamic sheet pin 23 is embedded in the external circuit board, thereby realizing the electrical connection between the dynamic sheet 2 and the external circuit and realizing the transmission of signal.The end of the dynamic sheet body 22 away from the guide core 1 is pressed on the base of the shaft body, thereby realizing the position fixation of the dynamic sheet, and preventing the dynamic sheet body 22 from being driven to move down by the dynamic sheet arm 21, which causes the guide core 1 to move up and cannot separate from the static sheet.

[0032] For the specific structure of the static sheet 3, as shown in FIG. 1 to FIG. 3 and FIG. 5, the static sheet 3 includes a static sheet body 31 located below the dynamic sheet body 22, at least one static sheet arm 32 arranged on the static sheet body 31 and extending transversely to the direction of the convex ridge 11, and at least one static sheet pin 33 arranged on the static sheet body 31 and extending downward as a whole, the static sheet pin 33 being electrically connected to an external circuit, specifically, the static sheet pin 33 being embedded in an external circuit board, thereby realizing the electrical connection between the static sheet 3 and the external circuit and the transmission of signals. The dynamic sheet arm 21 is driven by the convex ridge 11 under the action of the external force pressing the core 1 to realize contact or separation with the static sheet arm 32. Specifically, when the core 1 is pressed externally, the convex ridge 11 on the core 1 moves downward, and the lower end surface of the dynamic sheet arm 21 on the convex ridge 11 is pressed against the static sheet arm 32 under the elastic restoring force of the dynamic sheet arm 21, thereby realizing the closure of the circuit, and the static sheet pin 33 and the dynamic sheet pin 23 are embedded in the external circuit board, thereby transmitting the start signal to the conductive part of the external circuit board or the Hall element or the light-emitting diode, thereby awakening the conductive part on the shaft body and realizing the transmission of the operation signal. When the external force is removed from the core 1, the convex ridge 11 on the core 1 is moved upward under the driving of the reset spring in the shaft body, and the outermost side of the dynamic sheet arm 21 is lifted by the band-pass step, thereby separating the dynamic sheet arm 21 from the static sheet arm 32, and the circuit between the dynamic sheet 2 and the static sheet 3 is disconnected, and the conductive part of the external circuit board or the Hall element or the light-emitting diode is in a dormant state without conduction under the condition of not receiving the start signal, thereby realizing the purpose of saving power and reducing power consumption, improving the use time of the wireless keyboard, and facilitating the use of people. The end of the static sheet body 31 away from the core 1 is pressed against the base of the shaft body, thereby realizing the position fixation of the static sheet 3 and preventing the displacement of the static sheet body 31 during operation, which causes the dynamic sheet arm 21 to fail to normally conduct with the static sheet arm 32, thereby improving the conduction accuracy and efficiency of the structure.

[0033] Preferably, in order to improve the space utilization in the shaft body, as shown in FIG. 1 to FIG. 3 and FIG. 5, at least one static sheet slot 34 is formed on the static sheet body 31 to give way to the dynamic sheet pin 23, thereby making the dynamic sheet 2 and the static sheet 3 occupy less space in the shaft body, improving the space utilization in the shaft body, making the shaft body more portable, and facilitating the use.

[0034] Preferably, in order to further improve the space utilization in the shaft body, as shown in FIGS. 2-3 and 5, the static sheet pin 33 includes a first static sheet pin 331 extending downwardly from the static sheet body 31, and a second static sheet pin 332 arranged on the lower end side of the first static sheet pin 331 and extending downwardly after being bent towards the guide core 1. By arranging the second static sheet pin 332 to extend downwardly after being bent as a whole towards the guide core 1, the guide core 1 and other components in the shaft body are accommodated, facilitating the cooperation between the components, so that the static sheet 3 and the guide core 1 occupy less space in the shaft body, improving the space utilization in the shaft body, making the shaft body more portable, and facilitating use.

[0035] In order to prevent the guide core 1 from being unable to normally drive the dynamic sheet arm 21 when an external force presses the guide core 1 at different positions, as shown in FIGS. 1-5, the number of the dynamic sheet arms 21 is 3 groups, the number of the static sheet arms 32 is 3 groups corresponding to the dynamic sheet arms 21 one by one, and the number of the convex ridges 11 is also 3 groups corresponding to the dynamic sheet arms 21 one by one. The dynamic sheet arms 21 are respectively a first group of dynamic sheet arms 21 arranged on the side of the guide core 1, a second group of dynamic sheet arms 21 arranged in the middle of the guide core 1, and a third group of dynamic sheet arms 21 arranged on the other side of the guide core 1. Therefore, no matter which position of the guide core 1 is pressed by the external force, the convex ridges 11 on the guide core 1 can drive the dynamic sheet arms 21 to realize contact or separation with the static sheet arms 32.

[0036] Preferably, as shown in FIGS. 4 and 5, the two groups of dynamic sheet arms 21 arranged on the side edges are respectively provided with a dynamic sheet extension plate 211 extending transversely towards the convex ridges 11. Therefore, the convex ridges 11 drive the two groups of dynamic sheet arms 21 arranged on the side edges through the dynamic sheet extension plate 211, so that the dynamic sheet arms 21 are driven by the convex ridges 11 to realize contact or separation with the static sheet arms 32 under the action of the external force pressing the guide core 1, improving the efficiency and accuracy of the guide core 1 driving the dynamic sheet arms 21, and facilitating the cooperation between the components.

[0037] Preferably, as shown in FIGS. 4 and 5, the two groups of static sheet arms 32 arranged on the side edges are respectively provided with a static sheet extension plate 321 extending transversely towards the convex ridges 11 and directly opposite to the dynamic sheet extension plate 211. Therefore, the dynamic sheet extension plate 211 is favorably abutted against the static sheet extension plate 321, so as to realize the conduction of the dynamic sheet and the static sheet, and facilitate the cooperation between the components.

[0038] Preferably, as shown in Figure 7, in order to make the convex ridge 11 better drive the reed arm 21, the upper end of the convex ridge 11 is formed with a first guide inclined surface 111 extending obliquely from the inner upper direction to the outer lower direction. When the external force is removed from the guide core 1, the convex ridge 11 on the guide core 1 is moved upward and reset under the action of the reset spring in the shaft body. The first guide inclined surface 111 on the band-pass step first contacts the reed arm 21, so that the reed arm 21 is attached to the convex ridge 11 under the oblique guiding action of the first guide inclined surface 111, so that the convex ridge 11 better drives the reed arm 21, improves the efficiency and accuracy of the guide core 1 driving the reed arm 21, and facilitates the cooperation between the parts.

[0039] For the reed arm 21 being fixedly contacted with the convex ridge 11, or the guide core 1 being bent downward to separate from the convex ridge 11 under the action of the elastic restoring force when the guide core 1 is pressed, and then being driven by the convex ridge 11 when the guide core 1 moves upward, or the reed arm 21 being transversely arranged, the convex ridge 11 bends the reed arm 21 downward during the pressing process so that the reed arm 21 contacts the static reed arm 32, the reed arm 21 is restored to be transversely arranged under the elastic restoring force when the convex ridge 11 moves upward so as to be separated from the static reed arm 32, or other ways that can realize the contact or separation of the reed arm 21 and the static reed arm 32 driven by the convex ridge 11 can be used, which can be set according to the actual situation, so in this embodiment, no specific limitation is made.

[0040] Preferably, as shown in Figure 7, if the reed arm 21 is transversely arranged, the convex ridge 11 bends the reed arm 21 downward during the pressing process so that the reed arm 21 contacts the static reed arm 32, and the reed arm 21 is restored to be transversely arranged under the elastic restoring force when the convex ridge 11 moves upward so as to be separated from the static reed arm 32. The lower end of the convex ridge 11 can be formed with a second guide inclined surface 112 extending obliquely from the outer upper direction to the inner lower direction. When the guide core 1 is pressed by the external force, the second guide inclined surface 112 first contacts the reed arm 21. The reed arm 21 is more attached to the convex ridge 11 under the oblique guiding action of the second guide inclined surface 112, so as to be pressed downward by the convex ridge 11 until it contacts the static reed arm 32 to be conducted, thereby improving the efficiency and accuracy of the guide core 1 driving the reed arm 21, and facilitating the cooperation between the parts.
