Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments.

[0027] The utility model is further described below in conjunction with embodiments.

[0028] The terms “left”, “right”, “front”, “back”, “up” and “down” mentioned in the following description are oriented in the viewing direction of the front view.

[0029] Please refer to the instruction manual Figure 1-6 A keyboard axis includes an axis lower cover 20, an axis core 30, a trigger 40 and a pressing auxiliary mechanism 5.

[0030] The pins at the bottom of the shaft lower cover 20 are connected to the keyboard bottom plate. The shaft lower cover 20 has an inner cavity and an open top. A guide sleeve 34 is provided at the bottom of the inner cavity. A spring 33 is sleeved on the outer side of the guide sleeve 34. The top of the shaft lower cover 20 is buckled with the shaft upper cover 10, and the top of the shaft upper cover 10 is open.

[0031] The shaft core 30 is slidably inserted in the top opening of the shaft body upper cover 10, and a guide slide shaft 35 slidably inserted with a guide sleeve 34 is provided at the bottom of the shaft core 30. The guide slide shaft 35 moves in the guide sleeve 34. The spring 33 is used to assist the shaft core 30 in resetting and provide a pressing feel for the user. A top column 36 for engaging with a keycap is provided at the top of the shaft core 30, and the user presses the keycap to press the shaft core 30 downward.

[0032] Preferably, slide grooves 31 are provided on both sides of the top opening of the shaft upper cover 10 , and sliders 32 adapted to the slide grooves 31 are provided on both sides of the shaft core 30 , and the slide grooves 31 and the sliders 32 limit the shaft core 30 .

[0033] The trigger 40 is installed in the lower cover 20 of the shaft body, and the shaft core 30 can press and trigger the trigger 40. When the shaft core 30 moves to the set position, an electrical signal is sent through the trigger 40 to output the key pressing result.

[0034] The pressing auxiliary mechanism 5 is used to balance the pressure when the shaft core 30 is pressed.

[0035] In one embodiment, the pressing auxiliary mechanism 5 includes a rack 51, a first gear 52, a second gear 53, a first rotating shaft 54, a second rotating shaft 55, a first magnetic block 56 and a second magnetic block 57. The rack 51 is installed at the bottom of the shaft core 30, the first rotating shaft 54 ​​and the second rotating shaft 55 are respectively rotatably installed on the inner side of the lower cover 20 of the shaft body, the first gear 52 is installed on the first rotating shaft 54, the second gear 53 is installed on the second rotating shaft 55, the first gear 52 is respectively engaged with the rack 51 and the second gear 53, the second magnetic block 57 is installed at the bottom of the shaft core 30, the middle part of the first magnetic block 56 is installed on the second rotating shaft 55, and in the initial state, the end of the first magnetic block 56 and the second magnetic block 57 that repel each other at the bottom is facing upward.

[0036] Specifically, the first magnetic block 56 and the second magnetic block 57 are both neodymium magnets.

[0037] In the present invention, when the key is not pressed, it is in the initial state. The upward end of the first magnetic block 56 is close to the bottom end of the second magnetic block 57 and repels the second magnetic block 57. When the key cap is pressed, the rack 51 is driven to move vertically downward through the shaft core 30. The rack 51 drives the second gear 53 to rotate through the first gear 52, and then drives the second shaft 55 to rotate, so that the first magnetic block 56 rotates, and the end of the first magnetic block 56 and the second magnetic block 57 that are attracted to each other gradually approaches the direction of the second magnetic block 57. The rotating first magnetic block 56 and the second magnetic block 57 work together to achieve that when the key cap is just pressed, the first magnetic block 56 is displaced. The second magnetic block 57 is repelled, and the force required to press the shaft core 30 is increased. When the end of the first magnetic block 56 and the second magnetic block 57 that are attracted to each other gradually approaches the direction of the second magnetic block 57, the repulsive force between the first magnetic block 56 and the second magnetic block 57 is transformed into suction, and the suction gradually increases. In this process, the suction always balances the increasing rebound force of the spring 33 due to the downward pressure, so that the pressure required for pressing the keyboard shaft remains balanced, so that the pressure required when the shaft core 30 is just beginning to be pressed down and when the shaft core 30 is about to reach the stroke limit is always maintained within a specific range, thereby greatly increasing the pressing feel of the keyboard shaft.

[0038] When the shaft core 30 just begins to be pressed down, the pressing assist mechanism 5 increases the pressure required to press the shaft core 30 down, and the rebound force provided by the spring 33 is enhanced during the pressing process of the shaft core 30. When the shaft core 30 approaches its key travel limit, the pressing assist mechanism 5 balances the rebound force of the spring 33 by attracting the shaft core 30, making it easier for the user to press the keys and reducing the burden on the fingers. The pressing assist mechanism 5 can keep the force required to press the keyboard shaft balanced, so that the pressure required when the shaft core 30 just begins to be pressed down and when the shaft core 30 is about to reach the travel limit is always maintained within a specific range, thereby greatly increasing the pressing feel of the keyboard shaft.

[0039] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
