In the process of using computers, peripherals such as mice and keyboards are indispensable parts. For keyboard products, according to the current market keyboard usage, when the operator presses the keycap, the keycap feels very stiff after being pressed to the bottom. Long-term use will cause finger soreness and joint damage. Long-term use will make the operator feel poor and even cause finger joint damage. For this reason, most keyboard manufacturers will add elastic devices inside the keyboard shaft switch to ensure a better downward pressure experience, but because the fingers act on the keycaps, the keyboard itself has no downward pressure feedback, and long-term use is also easy to cause finger fatigue. In addition, the existing keyboards in the market do not have a design, or use a split design, which is complex to assemble, unstable in structure, and high in cost. At the same time, according to the existing market keyboards, they are not waterproof. If a cup of water is accidentally knocked over during use, the keyboard will fail and be scrapped. The service life of the keyboard will decrease in a working environment with high moisture content. If a keyboard with a simple structure and an elastic mechanism that is molded by one-piece injection molding can be designed to make typing on the keyboard feel better and not stiff, and at the same time the keyboard is designed with a waterproof function and has a floating feel suitable for use scenarios with waterproof requirements, the above problems can be solved.

[0019] like Figures 1 to 6 As shown, in this embodiment, the utility model includes a middle frame 1, a switch assembly 2 and a connecting assembly 3, the switch assembly 2 includes a plurality of elastic switches 21 and a plurality of key caps 22, the middle frame 1 is provided with a plurality of integrally formed elastic mechanisms 4, the plurality of integrally formed elastic mechanisms 4 make the frame portion and the panel portion of the middle frame 1 floatingly connected, the panel portion of the middle frame 1 is provided with a plurality of switch connecting positions 5, the plurality of the elastic switches 21 are connected to the plurality of the switch connecting positions 5, the connecting assembly 3 includes a PCBA board 31 and a bottom shell 32, the PCBA board 31 is connected to the lower end surface of the panel portion of the middle frame 1, and the contact ends of the plurality of the elastic switches 21 cooperate with the plurality of IC modules 6 on the PCBA board 31 through the plurality of the switch connecting positions 5. It can be seen that the plurality of integrally molded elastic mechanisms 4 and the middle frame 1 are integrally injection molded, and the frame portion and the panel portion of the middle frame 1 are connected together, so that the panel portion of the middle frame 1 and the frame portion of the middle frame 1 can float relatively, and the floating feedback when the key cap 22 is pressed down is increased. The integral injection molding will not cause abnormal noise due to relative friction between the assembly parts and the middle frame, and the assembly difficulty is low and the cost is lower.

[0020] like Figure 2 , Figure 5 as well as Figure 6 As shown, in this embodiment, the switch assembly 2 further includes a switch fixing plate 23, and the switch fixing plate 23 is provided with a plurality of through openings 7 adapted to the switch connection positions 5, and a plurality of elastic switches 21 are connected to the plurality of switch connection positions 5 through the plurality of through openings 7. It can be seen that the switch fixing plate 23 can stably fix the plurality of elastic switches 21 on the plurality of switch connection positions 5 on the middle frame 1 without relative shaking, and the use process is more stable.

[0021] like Figure 1 and Figure 3 As shown, in this embodiment, the upper connection ends of the plurality of elastic switches 21 are connected to the plurality of key caps 22. It can be seen that the key caps 22 are connected to the upper connection ends of the plurality of elastic switches 21, and the movable end of the elastic switch 21 can be driven downward by pressing the key cap 22 so that the lower contact end of the elastic switch 21 contacts the IC module 6, so that the Hall value changes and triggers the IC module 6 to respond.

[0022] like Figure 2 and 3As shown, in this embodiment, the switch connection position 5 and the lower end surface of the PCBA board 31 are both sealed with waterproof glue. It can be seen that the lower end surface of the PCBA board 31 and the switch connection position 5 are connected with the upper end surface of the PCBA board 31 for waterproof sealing. When water enters, the excess water is discharged through the holes of the drainage cylinders 8, which can effectively avoid the risk of keyboard failure and scrapping after water ingress, reduce losses, and is suitable for use scenarios with waterproof requirements.

[0023] like Figure 2 and Figure 3 As shown, in this embodiment, the switch connection position 5 is provided with a plurality of drainage cylindrical holes 8, and the PCBA board 31 is provided with a plurality of through holes 9 adapted to the drainage cylindrical holes 8. The plurality of drainage cylindrical holes 8 are limitedly matched with the plurality of through holes 9, and water flows into the bottom shell 32 through the plurality of drainage cylindrical holes 8. It can be seen that the limitedly matched plurality of drainage cylindrical holes 8 and the plurality of through holes 9 can make the PCBA board 31 and the lower end surface of the middle frame 1 fit together, making the keyboard smaller in size and having better waterproof performance after sealing.

[0024] like Figure 2 and Figure 3 As shown, in this embodiment, the elastic switch 21 contacts or separates from the IC module 6, and the plurality of the integrally formed elastic mechanisms 4 bend and deform up and down, causing the panel portion of the middle frame 1 to descend or ascend. It can be seen that as the key cap 22 is pressed to drive the movable end of the elastic switch 21 downward, the panel portion of the middle frame 1 will float downward under the downward force during the downward pressing process, and will provide an upward force after releasing the key cap 22, which can provide downward pressing feedback and floating for the operator's hand, providing a better feel and preventing the operator's hand from getting tired easily.

[0025] like Figure 4 As shown, in this embodiment, the bottom shell 32 is set as a disc-shaped structure with a higher rear end. It can be seen that the bottom shell 32 is set as a disc-shaped structure with a higher rear end, which is convenient for centralized collection of water, has a simple structure and stable performance.

[0026] like Figure 2 and Figure 4 As shown, in this embodiment, the bottom shell 32 is connected to the lower end surface of the frame portion of the middle frame 1 by a plurality of screws 10. It can be seen that the bottom shell 32 and the middle frame 1 can be connected by a plurality of screws 10, making the keyboard structure more stable.

[0027] The working principle of the utility model is as follows: the operator presses several of the keycaps 22 with his fingers to transmit the force to several of the elastic switches 21, and the lower contact end of the elastic switch 21 is pressed down. During the pressing process, the panel part of the middle frame 1 is received downward, and floats downward through several of the one-piece elastic mechanisms 4 to provide downward pressure feedback. The lower contact end of the elastic switch 21 cooperates with several of the IC modules 6 to cause the Hall value change to trigger the IC module 6 to respond. When the finger is released, the panel part of the middle frame 1 floats upward under the action of several of the one-piece elastic mechanisms 4, so that the operator's operating experience is better. When the keyboard is accidentally flooded, the PCBA board 31 and the matching part of the switch connection position 5 and the lower end surface of the PCBA board 31 are all waterproof and sealed with glue. Moisture will not enter the component part of the PCBA board 31 to cause short circuit damage. The water flow is discharged into the bottom shell 32 through several of the drainage cylindrical holes 8 for unified collection, which can make the keyboard feel better and not stiff. At the same time, the keyboard is designed with a waterproof function and is suitable for use scenarios with waterproof requirements.

[0028] Although the embodiments of the present invention are described with practical solutions, they do not constitute limitations on the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
