[0035] The present application will be further described below in combination with the drawings. EMBODIMENT

[0036] As Figures 3 to 13 shown in the adjusting structure with the adjusting keyboard elastic function, comprising a lower cover 1, a plurality of springs 2, a push block 3 and a base 4.

[0037] The lower cover 1 is reciprocally slid on the base 4, and the specific structure is that the guide column 41 is fixedly arranged on the base 4, the guide hole 11 is arranged on the lower cover 1, the guide column 41 is slid in the guide hole 11, the guide column 41 is arranged upward, and the lower cover 1 can be slid up and down along the guide column 41.

[0038] The spring 2 is compressed between the lower cover 1 and the base 4, and the specific structure is that the lower cover 1 is provided with a spring groove 12 at one end close to the base 4, the base 4 is fixedly provided with a limiting column 42 at one end close to the lower cover 1, one end of the spring 2 is located in the spring groove 12, and the other end of the spring 2 is sleeved on the limiting column 42; when the lower cover 1 slides downward along the guide column 41, the lower cover 1 compresses the spring 2, kinetic energy is converted into elastic potential energy; when the spring 2 is stretched under the action of its own elastic force, the lower cover 1 is pushed to move upward, and the elastic potential energy is converted into kinetic energy. In the process of mutual conversion, energy is inevitably lost, and the lower cover 1 is buffered under the action of the spring 2.

[0039] In the embodiment, the spring 2 is a conical spring, which has the advantages that the diameter of the conical spring is wide at the top and narrow at the bottom, the elastic coefficients of different parts change when the spring is compressed, a nonlinear pressure curve is formed, the force change in the pressing process is more in line with the ergonomic requirements, for example, the initial touch is triggered, and the resistance is enhanced in the middle and rear sections. Meanwhile, the design of the conical spring reduces the friction area between the inner walls, and a smoother pressing experience is achieved. The design of the conical spring is a non-equidistant structure, which reduces the resonance frequency and reduces the abnormal sound generated by the vibration of the metal coil.

[0040] The push block 3 is slidably arranged on the lower cover 1, and then clamped between the lower cover 1 and the base 4 or separated from the lower cover 1 and the base 4, and the specific structure is that the lower cover 1 is provided with a sliding groove 13, the push block 3 is fixedly provided with a clamping hook 31, the push block 3 is slidably arranged in the sliding groove 13 through the clamping hook 31, and the design of the clamping hook 31 enables the push block 3 to be clamped in the sliding groove 13 and enables the push block 3 to slide back and forth along the sliding groove 13.

[0041] On the other hand, the lower cover 1 is provided with a limiting groove 14, the push block 3 is fixedly provided with a limiting strip 32, the limiting strip 32 and the limiting groove 14 are matched with each other, the limiting groove 14 has two front and rear positions, when the push block 3 is clamped between the lower cover 1 and the base 4 by people, the limiting strip 32 on the push block 3 is clamped in the front limiting groove 14, and when the push block 3 is separated from the lower cover 1 and the base 4 by people, the limiting strip 32 on the push block 3 is clamped in the rear limiting groove 14, thereby preventing the push block 3 from loosening when people use the keyboard.

[0042] The base 4 is provided with a notch 43 matched with the push block 3, and the notch 43 is designed to prevent the push block 3 from being clamped between the lower cover 1 and the base 4 when the push block 3 is separated from the lower cover 1 and the base 4, thereby facilitating the relative movement between the lower cover 1 and the base 4.

[0043] The push block 3 is fixedly provided with anti-skid lines, the anti-skid lines are used to increase the friction between the fingers and the push block 3, and the push block 3 is not easy to slip.

[0044] Working principle: The traditional keyboard is directly installed on the lower cover 1;

[0045] For people who don't use the keyboard frequently, when using it, slide the push block 3 so that it is locked between the lower cover 1 and the base 4. At this time, the lower cover 1, the push block 3 and the base 4 form a whole. When people type on the keyboard, the spring 2 is not under force, and the keyboard is directly subjected to the striking force of the fingers on the lower cover 1, the push block 3 and the base 4.

[0046] For users who use the keyboard very frequently, when using it, sliding the push block 3 away from the bottom cover 1 and the base 4 allows the keyboard to absorb the impact of the fingers' striking force. The bottom cover 1 then presses down the spring 2, converting the kinetic energy of the pressure into elastic potential energy. This further cushions the impact of the fingers' striking force, thereby further reducing the impact of the keyboard keys 51 and effectively alleviating finger fatigue. On the other hand, the additional cushioning effect of the spring 2 also reduces the hard collision between the keyboard keys 51, thus reducing wear and extending the service life. Example

[0047] like Figures 1 to 13 The keyboard shown includes the adjustment structure in Embodiment 1, and further includes: a key 51, a top cover 52, an upper cover 53, a positioning plate 54, a sound-absorbing cotton 55, a PCB board 56, and a reinforcing plate 57. The top cover 52, upper cover 53, positioning plate 54, sound-absorbing cotton 55, PCB board 56, reinforcing plate 57, lower cover 1, and base 4 are arranged sequentially. The key 51 passes through the top cover 52, upper cover 53, positioning plate 54, and sound-absorbing cotton 55, and is electrically connected to the PCB board 56.

[0048] Decorative parts 58 are fixedly installed on both the top cover 53 and the base 4, and a foot bracket 59 is fixedly installed at the bottom of the base 4.

[0049] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of protection of the present utility model. Therefore, any equivalent changes made in accordance with the scope of the patent application of the present utility model shall still fall within the scope of the present utility model.
