[0002] With the rapid development of technology, keyboards have become an indispensable part of our daily life and work. For the convenience of travel, wireless keyboards have emerged on the market at present. They are internally provided with batteries and transmit input information to a special receiver inserted into a computer through infrared rays or radio waves, thereby realizing signal transmission.

[0003] Conventional key switches are generally installed on a keyboard circuit board and are always conducting with the keyboard circuit board. This method will cause a high power consumption rate of the wireless keyboard on a wireless keyboard, and it often needs to be charged, which is not conducive to people's daily use. Content of the Utility Model

[0004] In view of the above deficiencies, the purpose of the utility model is to provide a wake-up conduction structure for a key switch, which can be applied to shaft bodies such as Hall magnetic shafts and optical shafts, has a large application range, wakes up the original conduction structure of the Hall magnetic shaft, optical shaft and other shaft bodies when being pressed to realize signal transmission, and has no interference with the original conduction structure of the Hall magnetic shaft, optical shaft and other shaft bodies when not being pressed, so that the Hall magnetic shaft, optical shaft and other shaft bodies enter the sleep state, thereby achieving the purpose of saving the power of the wireless keyboard, reducing power consumption, increasing the service life of the wireless keyboard, and being beneficial to people's use.

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

[0006] A wake-up conduction structure for a key switch includes a guide core, a moving piece located on the side of the guide core, and a static piece arranged below the moving piece. At least one convex rib is formed on the side of the guide core. The moving piece includes at least one moving piece arm extending horizontally towards the convex rib. The moving piece arm is driven by the convex rib to contact or separate from the static piece under the action of an external force pressing the guide core. The moving piece and the static piece are respectively electrically connected to an external circuit, and the moving piece and the static piece are stacked up and down.

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

[0008] As a further improvement of the present utility model, the stationary sheet includes a stationary sheet body located below the movable sheet body, at least one stationary sheet arm disposed on the stationary sheet body and extending horizontally towards the convex rib, and at least one stationary sheet pin integrally formed on the stationary sheet body. The stationary sheet pin is electrically connected to an external circuit. The movable sheet arm is driven by the convex rib to contact or separate from the stationary sheet arm under the action of an external force pressing the guide core.

[0009] As a further improvement of the present utility model, at least one stationary sheet relief groove for accommodating the movable sheet pin is formed on the stationary sheet body.

[0010] As a further improvement of the present utility model, the stationary sheet pin includes a first stationary sheet pin extending downward and bent from the stationary sheet body, and a second stationary sheet pin disposed on the side of the lower end of the first stationary sheet pin, bent towards the guide core and then extending downward.

[0011] As a further improvement of the present utility model, the number of movable sheet arms is 3 groups, the number of stationary sheet arms is 3 groups corresponding one-to-one to the movable sheet arms, and the number of convex ribs is also 3 groups corresponding one-to-one to the movable sheet arms.

[0012] As a further improvement of the present utility model, a first guiding inclined surface is formed at the upper end of the convex rib.

[0013] As a further improvement of the present utility model, a second guiding inclined surface is formed at the lower end of the convex rib.

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

[0015] By setting the wake-up conduction structure to include a guide core, a moving piece located on the side of the guide core and elastically bent downward as a whole, and a static piece arranged below the moving piece, at least one convex rib is formed on the side of the guide core. The moving piece includes at least one moving piece arm extending horizontally towards the convex rib. The moving piece arm is driven by the convex rib under the action of an external force pressing the guide core to achieve contact or separation from the static piece. The moving piece and the static piece are respectively electrically connected to an external circuit. This wake-up conduction structure can be installed on different types of shafts such as Hall shafts and optical shafts, so as to serve as the wake-up structure of different types of shafts. It has a large application range and is more practical. Its specific operation method is that when an external force presses the guide core, the guide core drives the convex rib on it to move downward, so that the lower end surface presses against the moving piece arm on the convex rib, and the moving piece arm under its own elastic restoring force presses downward against the static piece, thereby realizing the closure of the circuit and transmitting the start signal to the conduction components of the shaft such as an external circuit board, a Hall element, or a light-emitting diode, waking up the conduction components on the shaft, and thus realizing the transmission of operation signals. When the external force is removed from the guide core, the guide core is driven by the reset spring in the shaft to move the convex rib on it upward to reset. The convex rib lifts the outermost side of the moving piece arm, so that the moving piece arm is separated from the static piece, and the circuit between the moving piece and the static piece is disconnected. The conduction components of the shaft such as an external circuit board, a Hall element, or a light-emitting diode are in a dormant state without conduction when they do not receive the start signal, thereby achieving the purpose of saving power, reducing power consumption, increasing the usage time of the wireless keyboard, and facilitating people's use. By arranging the moving piece and the static piece in parallel and stacked up and down, the stroke of the moving piece and the static piece can be very short, so as to wake up the Hall element before the Hall element senses the magnet signal and ensure the timely and accurate transmission of signals.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] Please refer to Figures 1 to 6The embodiment of the utility model provides a wake-up conduction structure for a key switch, including a guide core 1, a movable plate 2 located on the side of the guide core 1 and elastically bent downward as a whole, and a static plate 3 arranged below the movable plate 2, at least one convex ridge 11 is formed on the side of the guide core 1, the movable plate 2 includes at least one movable plate support arm 21 extending laterally in the direction of the convex ridge 11, the movable plate support arm 21 is driven by the convex ridge 11 to achieve contact or separation with the static plate 3 under the force of external force pressing the guide core 1, the movable plate 2 and the static plate 3 are electrically connected to the external circuit respectively, and the movable plate 2 and the static plate 3 are stacked up and down in parallel with each other. The present wake-up conduction structure can be installed on different types of shafts such as Hall shafts, optical shafts, etc., so as to serve as a wake-up structure for different types of shafts, and has a wide range of applications and is more practical.

[0030] The specific operation mode is that when the external force presses the guide core 1, the guide core 1 drives the convex rib 11 thereon to move downward, so that the movable arm 21 whose lower end face is pressed against the convex rib 11 is pressed downward against the static plate 3 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 or the conductive component of the shaft body such as the Hall element or the light-emitting diode, waking up the conductive component on the shaft body, thereby realizing the transmission of the operation signal. When the external force is separated from the guide core 1, the guide core 1 is driven by the reset spring in the shaft body to move the convex rib 11 thereon upward and reset, and the convex rib 11 lifts the outermost side of the movable arm 21, thereby separating the movable arm 21 from the static plate 3, disconnecting the circuit between the movable plate 2 and the static plate 3, and the conductive component of the shaft body such as the external circuit board or the Hall element or the light-emitting diode 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 moving plate 2 and the static plate 3 in parallel with each other, the travel of the moving plate 2 and the static plate 3 can be very short, so that the conductive components of the Hall element or light-emitting diode can be awakened before sensing other structures or starting, thereby ensuring timely and accurate signal transmission.

[0031] Regarding the specific structural arrangement of the moving piece 2, as shown in FIG. Figures 1 to 4 As shown, the movable piece 2 also includes a movable piece body 22, and at least one movable piece pin 23 disposed on the movable piece body 22 and bent and extended downward, the movable piece support arm 21 is disposed on the movable piece body 22, and the movable piece pin 23 is electrically connected to the external circuit, specifically, the movable piece pin 23 is embedded in the external circuit board, so as to realize the electrical connection between the movable piece 2 and the external circuit and realize the signal transmission. The end of the movable piece body 22 away from the guide core 1 is pressed against the base of the shaft body, so as to realize the position fixing of the movable piece, and prevent the movable piece body 22 from being driven downward by the movable piece support arm 21, so as to prevent the guide core 1 from being unable to separate from the static piece when moving upward.

[0032] Regarding the specific structural arrangement of the static piece 3, as shown in FIG. Figures 1 to 3 as well as Figure 5 As shown, the static piece 3 includes a static piece body 31 located below the moving piece body 22, at least one static piece arm 32 arranged on the static piece body 31 and extending laterally toward the convex rib 11, and at least one static piece pin 33 arranged on the static piece body 31 and bent downward as a whole, wherein the static piece pin 33 is electrically connected to an external circuit, specifically, the static piece pin 33 is embedded in an external circuit board, thereby realizing electrical connection between the static piece 3 and the external circuit and signal transmission. The movable arm 21 is driven by the convex ridge 11 to contact or separate from the static arm 32 under the action of external force pressing the guide core 1. Specifically, when the guide core 1 is pressed externally, the guide core 1 drives the convex ridge 11 thereon to move downward, so that the movable arm 21, whose lower end face is pressed against the convex ridge 11, presses downward against the static arm 32 under its own elastic restoring force, thereby closing the circuit, and embedding the static pin 33 and the movable pin 23 into the external circuit board, thereby transmitting the start signal to the external circuit board or the conductive component of the shaft body such as the Hall element or the light-emitting diode, thereby waking up the conductive component on the shaft body and transmitting the operation signal. When the external force is separated from the guide core 1, the guide core 1 moves up and resets the convex ridge 11 driven by the reset spring in the shaft body, and the pass step lifts the outermost side of the movable arm 21, thereby separating the movable arm 21 from the static arm 32, disconnecting the circuit between the movable plate 2 and the static plate 3, and the external circuit board or Hall element or light-emitting diode and other conductive parts of the shaft body are dormant and non-conductive when no start signal is received, thereby saving power and reducing power consumption, increasing the use time of the wireless keyboard, and facilitating people's use. The end of the static plate body 31 away from the guide core 1 is pressed against the base of the shaft body, thereby fixing the position of the static plate 3, preventing the static plate body 31 from shifting during operation, causing the movable arm 21 to be unable to conduct normally with the static arm 32, and improving the conduction accuracy and efficiency of the present structure.

[0033] Preferably, in order to improve the space utilization in the shaft body, as Figures 1 to 3 as well as Figure 5 As shown, at least one static piece giving way groove 34 is formed on the static piece body 31 to give way to the moving piece pin 23. By setting the static piece giving way groove 34 to give way to the moving piece pin 23, the space occupied by the moving piece 2 and the static piece 3 in the shaft body is reduced, thereby improving the space utilization rate in the shaft body, making the shaft body lighter and easier to use.

[0034] Preferably, in order to further improve the space utilization rate in the shaft body, as Figures 2 to 3 as well as Figure 5As shown, the stationary contact pin 33 includes a first stationary contact pin 331 that extends downward and bends from the stationary contact body 31, and a second stationary contact pin 332 that is disposed on the lower side edge of the first stationary contact pin 331, bends in the direction of the guiding core 1, and then extends downward. By arranging the second stationary contact pin 332 to bend in the direction of the guiding core 1 as a whole and then extend downward, the guiding core 1 and other components within the shaft body can be given way, facilitating the cooperation between the components. As a result, the occupied space of the stationary contact 3 and the guiding core 1 within the shaft body is smaller, the space utilization rate within the shaft body is improved, the shaft body is made lighter, and it is more convenient for use.

[0035] To prevent the situation where the guiding core 1 cannot drive the moving contact arm 21 normally when an external force presses different positions of the guiding core 1, as Figures 1 to 5 shown, the number of the moving contact arms 21 is 3 groups, the number of the stationary contact arms 32 is 3 groups corresponding one-to-one to the moving contact arms 21, and the number of the convex ribs 11 is also 3 groups corresponding one-to-one to the moving contact arms 21. The moving contact arms 21 are respectively a first group of moving contact arms 21 disposed on the side of the guiding core 1, a second group of moving contact arms 21 disposed in the middle of the guiding core 1, and a third group of moving contact arms 21 disposed on the other side of the guiding core 1. Thus, no matter which position of the guiding core 1 is pressed by an external force, the convex ribs 11 on the guiding core 1 can drive the moving contact arms 21 to make contact with or separate from the stationary contact arms 32.

[0036] Preferably, as Figure 4 and Figure 5 shown, two groups of moving contact arms 21 disposed on the side are respectively provided with a moving contact extension plate 211 that extends horizontally in the direction of the convex rib 11, which is beneficial for the convex rib 11 to drive the two groups of moving contact arms 21 disposed on the side through the moving contact extension plate 211. Furthermore, the moving contact arms 21 can be driven by the convex rib 11 under the action of an external force pressing the guiding core 1 to make contact with or separate from the stationary contact arms 32, improving the efficiency and accuracy of the guiding core 1 driving the moving contact arms 21, and facilitating the cooperation between the components.

[0037] Preferably, as Figure 4 and Figure 5 shown, two groups of stationary contact arms 32 disposed on the side are respectively provided with a stationary contact extension plate 321 that extends horizontally in the direction of the convex rib 11 and is opposite to the moving contact extension plate 211, which is beneficial for the moving contact extension plate 211 to correspondingly abut against the stationary contact extension plate 321, thereby realizing the conduction between the moving contact and the stationary contact, and facilitating the cooperation between the components.

[0038] Preferably, as Figure 7As shown, in order to better drive the moving piece arm 21 by the convex rib 11, a first guiding inclined surface 111 is formed at the upper end of the convex rib 11, which extends obliquely from the inner upper direction to the outer lower direction. When the external force is removed from the guide core 1, the guide core 1 is driven by the return spring in the shaft body to move the convex rib 11 thereon upward for resetting. The first guiding inclined surface 111 on the stepped through hole first contacts the moving piece arm 21, so that the moving piece arm 21 fits with the convex rib 11 under the guiding action of the inclined first guiding inclined surface 111, enabling the convex rib 11 to better drive the moving piece arm 21, improving the efficiency and accuracy of the guide core 1 driving the moving piece arm 21, and facilitating the cooperation between components.

[0039] Regarding whether the moving piece arm 21 is fixedly abutted against the convex rib 11, or the guide core 1 is bent downward under the action of its own elastic restoring force when being pressed and disengages from the convex rib 11, and then is driven by the convex rib 11 again when the guide core 1 moves upward, or the moving piece arm 21 is horizontally arranged, and the convex rib 11 presses down and bends the moving piece arm 21 during the downward pressing process so that the moving piece arm 21 contacts the static piece arm 32, and the moving piece arm 21 returns to the horizontal setting under its own elastic restoring force when the convex rib 11 moves upward and thus separates from the static piece arm 32, or other ways that can realize the moving piece arm 21 being driven by the convex rib 11 to contact or separate from the static piece arm 32 are all acceptable, and it can be set according to the actual situation, so no specific limitation is made in this embodiment.

[0040] Preferably, as Figure 7 shown, if the moving piece arm 21 is horizontally arranged, and the convex rib 11 presses down and bends the moving piece arm 21 during the downward pressing process so that the moving piece arm 21 contacts the static piece arm 32, and the moving piece arm 21 returns to the horizontal setting under its own elastic restoring force when the convex rib 11 moves upward and thus separates from the static piece arm 32, a second guiding inclined surface 112 can be formed at the lower end of the convex rib 11, which extends obliquely from the outer upper direction to the inner lower direction. When the external force presses the guide core 1 downward, the second guiding inclined surface 112 first contacts the moving piece arm 21, and the moving piece arm 21 fits better with the convex rib 11 under the guiding action of the inclined second guiding inclined surface 112, and thus is pressed downward by the convex rib 11 until it contacts and conducts with the static piece arm 32, improving the efficiency and accuracy of the guide core 1 driving the moving piece arm 21, and facilitating the cooperation between components.

[0041] It should be noted here that the wake-up conduction structure for the key switch disclosed by the present utility model is an improvement on the specific structure, and the specific control method is not the innovation point of the present utility model.

Their structures, principles and control methods are all known to those skilled in the art through technical manuals or obtained through conventional experimental methods.

[0042] The above is only a preferred embodiment of the present utility model, and does not impose any limitation on the technical scope of the present utility model. Therefore, other structures obtained by adopting the same or similar technical features as those of the above embodiments of the present utility model are all within the protection scope of the present utility model.
