[0034] Please refer to Fig. 1 to Fig. 9, the utility model embodiment provides a kind of ultra-thin keyboard open balance bracket spring piece reset structure, including a substrate 1, a first balance bracket 2 rotationally arranged on the substrate 1, a second balance bracket 3 rotationally arranged on the substrate 1, an upper cover 4 arranged on the first balance bracket 2 and second balance bracket 3, a reset elastic body 5 between the first balance bracket 2 and second balance bracket 3, first balance bracket 2 and second balance bracket 3 cross each other and can be superimposedly hinged together, the reset elastic body 5 is spring piece, the spring piece is V-shaped as a whole, and two ends thereof are inclined upward and extend and press on the upper cover 4 respectively, and the lower part of the reset elastic body 5 is fixed on the substrate 1.

[0035] When external force presses down the upper cover 4, the upper cover 4 is pressed on the first balance bracket 2 and the second balance bracket 3, thereby pressing down the first balance bracket 2 and the second balance bracket 3, and at the same time, the upper cover 4 also presses on the reset elastic body 5, so that the reset elastic body 5 is pressed down and deformed. After the external force is removed from the upper cover 4, the reset elastic body 5 resets and rebounds under its own elastic restoring force, thereby lifting the upper cover 4, and the first balance bracket 2 and the second balance bracket 3 are arranged on the upper cover 4, thereby lifting the first balance bracket 2 and the second balance bracket 3 to reset, completing the reset action of the key switch. The whole process is accurate and smooth, and the reset effect is good.

[0036] By setting the reset elastic body as a spring piece, the spring piece has good elastic potential and can quickly recover to its original state after being stressed, thereby effectively improving the balance bracket reset efficiency and further improving the reset efficiency of the key switch. The spring piece is low in cost, effectively reducing the production cost of the reset structure. The overall height of the spring piece can be set according to actual conditions, achieving a process with low height but high elasticity, ensuring that the pressing feeling is good and meeting the light and thin use demand, which is beneficial to use.

[0037] By setting the spring piece as V-shaped, two ends thereof press on the lower end surface of the upper cover 4, thereby making the conduction effect of the upper cover 4 better, and no matter which part of the upper cover 4 is pressed, the spring piece can be stressed, thereby realizing deformation and resetting, improving the reset efficiency of the reset structure, improving the reset accuracy of the reset structure, and ensuring the reset effect of the reset structure.

[0038] For the specific way that the reset elastic body 5 is fixed on the substrate 1, the lower part of the reset elastic body 5 can be welded on the substrate 1, can be a structure integrally formed with the substrate 1, or can be provided with limiting plates on both sides of the substrate 1 to limit the reset elastic body 5. It can be achieved that the reset elastic body 5 is fixed on the substrate 1, and therefore is not specifically limited in the embodiment.

[0039] Preferably, as shown in FIGS. 2-3, the two ends of the reset elastic body 5 extending upward are respectively provided with a pressing portion 51 bent outward and downward, and the top end of the pressing portion 51 is pressed against the upper cover 4. The bent structure makes the upper end of the reset elastic body 5 more rounded, and the upper cover 4 is not damaged in the pressing process. It is also beneficial to the pressing operation of the reset elastic body, so as to ensure the service life of the reset structure and improve the reset accuracy of the reset structure.

[0040] Preferably, as shown in FIG. 2, the pressing portion 51 of the reset elastic body 5 near one end of the second balance frame 3 is located above the second balance frame 3, so that when the upper cover 4 is pressed against the pressing portion 51, the pressing portion 51 can also be pressed against the second balance frame 3, thereby synchronously pressing the first balance frame 2 pivoted to the second balance frame 3, and the on component in the key switch is turned on.

[0041] Preferably, the pressing portion 51 of the reset elastic body 5 near one end of the first balance frame 2 is located above the first balance frame 2, so that when the upper cover 4 is pressed against the pressing portion 51, the pressing portion 51 can also be pressed against the first balance frame 2, thereby synchronously pressing the second balance frame 3 pivoted to the first balance frame 2, and the on component in the key switch is turned on.

[0042] For the specific way of fixed installation of the upper cover 4, as shown in FIGS. 4-6, one end of the upper cover 4 is provided with a second upper limiting block 41 embedded in the second balance frame 3, and the other end of the second balance frame 3 is formed with a second upper limiting hole 31 for the rotation of the second upper limiting block 41. The substrate 1 is installed on the circuit board of the keyboard. When an external force presses the upper cover 4, the second upper limiting block 41 on the upper cover 4 is embedded in the second upper limiting hole 31, thereby driving the second balance frame 3 to move downward. Since the first balance frame 2 and the second balance frame 3 are crossed and pivotally connected together, the second balance frame 3 synchronously drives the first balance frame 2 to move downward, and the reset elastic body 5 is pressed and deformed. After the multi-angle and multi-aspect balance of the key switch is moved downward, the conduction component in the key switch is conducted to output the signal outward, which is beneficial to the cooperation between the components. When the external force is removed from the upper cover 4, the reset elastic body 5 is reset under the elastic recovery force of itself, the reset elastic body 5 rebounds to reset the upper cover 4, and the conduction between the conduction components is disconnected, waiting for the next use. The whole process is smooth, the structure is simple, and it is beneficial to production and use, the reset is accurate and smooth, and the reset effect is good.

[0043] For the specific structure of the conduction component, the conduction component can be a mechanical spring conduction, a light conduction, a magnetic shaft conduction, a magnetic induction conduction, etc. These conduction structures are conventional technical means in the art, and therefore will not be described in detail in this embodiment.

[0044] For the specific structure of the second upper limiting hole 31, as shown in FIGS. 4-6, the second balance frame 3 includes a second plate body 32 pivotally arranged on the substrate 1, and a second extension plate 33 formed at one end of the second plate body 32 and extending upward. The second upper limiting hole 31 is arranged at one end of the second plate body 32, or arranged on the second extension plate 33, or arranged at the connection between the second plate body 32 and the second extension plate 33. The specific arrangement can be made according to the actual situation, and therefore will not be specifically limited in this embodiment.

[0045] For the specific structure of the second upper limiting block 41, as shown in FIGS. 4-6, the second upper limiting block 41 is in the shape of L as a whole, and the horizontal part is hooked on the second upper limiting hole 31, so that the upper cover 4 can be hooked on the second upper limiting hole 31 through the second upper limiting block 41, thereby driving the second balance frame 3 to move downward and upward reset. The structure of L shape only needs to pass the horizontal part of the second upper limiting block 41 through the second upper limiting hole 31 when assembling, and the overall structure is simple, convenient to install, beneficial to production, accurate and smooth in reset, and good in reset effect. The second hook plate and the second lower limiting block 34 are arranged on the second plate body 32.

[0046] When the external force presses the upper cover 4, the upper cover 4 moves downward and presses on the second extension plate 33, driving the second extension plate 33 to move downward, thereby driving the second balance frame 3 to move downward. When the external force is removed from the upper cover 4, the reset elastic body 5 is elastically reset under the elastic restoring force of itself, the second upper limit block 41 on the upper cover 4 presses on the upper end face of the second upper limit hole 31, thereby lifting and resetting the second balance frame 3, driving the first balance frame 2 and the second balance frame 3 to move upward and reset, thereby improving the resetting efficiency of the mounting structure.

When assembling, the first upper limit blocks 21 only need to be aligned and embedded in the first upper limit holes 42, and the overall structure is simple, convenient to install, and beneficial to production.

[0048] When the external force presses the upper cover 4, the upper cover 4 drives the second balance frame 3 to press downward, and the upper cover 4 drives the first upper limit block 21 to press downward through the first upper limit hole 42, while the first upper limit block 21 rotates on the first upper limit hole 42, thereby realizing the normal downward movement of the first balance frame 2 driven by the upper cover 4, and the first balance frame 2 and the second balance frame 3 cooperate with each other to make the key switch move uniformly downward regardless of the position of the upper cover 4 pressed by the external force, thereby realizing the conduction of the conduction assembly in the key switch and completing the signal output. When the external force is removed from the upper cover 4, the reset elastic body 5 is reset under the elastic restoring force of itself, the reset elastic body 5 lifts the first balance frame 2 and the second balance frame 3, the first upper limit block 21 rotates on the first upper limit hole 42, and the three cooperate to lift and reset the upper cover 4, so that the conduction between the conduction assemblies is disconnected, waiting for the next use. The whole process is reset accurately and smoothly, and the resetting effect is good.

[0049] For the specific way that the second balance frame 3 is arranged to rotate on the base plate 1, as shown in FIGS. 1-4, 5, and 8 and 9, the other end of the second balance frame 3 is formed with a second lower limit block 34 that is arranged to rotate into the base plate 1 on both sides, and the one end of the base plate 1 is formed with a second lower limit hole 11 into which the second lower limit block 34 is arranged to rotate. When assembly is required, the second lower limit block 34 is only arranged to rotate into the second lower limit hole 11, and the overall structure is simple, convenient to install, and beneficial to production. The base plate 1 is arranged on the circuit board of the keyboard, so that the second balance frame 3 is limited on the base plate 1, the normal operation of the second balance frame 3 is ensured, and the second balance frame 3 rotates in the second lower limit hole 11 during the process of moving down or moving up and resetting, so that the flexibility of the second balance frame 3 is ensured, the resetting process is accurate and smooth, and the resetting effect is good.
