Description

Technical Field

[0001] The present application relates to the technical field of keyboards, and in particular to a magnetic touch sensitive keyboard. Background Art

[0002] Mechanical keyboards are favored by many computer users, programmers and game players. Since each key has a separate switch to control the closure, people have produced a magnetic touch sensitive keyboard in order to have a better experience of using mechanical keyboards.

[0003] As for the existing magnetic touch sensitive keyboard, its internal structure is too simple, resulting in insufficient key feedback and lack of the trigger sound of a mechanical keyboard. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a magnetic touch sensitive keyboard to solve the problem of insufficient trigger sound feedback of mechanical keyboards.

[0005] The above-mentioned application purpose of the present application is achieved through the following technical solutions: a magnetic touch sensitive keyboard, including a keyboard axis shell, characterized in that the keyboard axis shell is composed of an upper cover and a lower shell, and a sliding handle is accommodated in the keyboard axis shell, a keycap is connected to the top of the sliding handle, and a protective cover is fixedly connected to the bottom of the sliding handle, the protective cover is fixedly installed above the magnetic axis, spring sheets are provided on both sides of the magnetic axis, and spherical flanges are respectively provided on the lower parts of the sides of the spring sheets on both sides, the lower shell is provided with a guide tube perpendicular to the bottom of the lower shell, the inner wall of the guide tube has a circular groove, and a support spring located below the magnetic axis is placed in the guide tube.

[0006] Furthermore, an inclined surface is provided at the opening of the guide tube.

[0007] Furthermore, a limit spring is connected between the two spring sheets and the magnetic axis.

[0008] Furthermore, a protective cover is provided above the magnetic axis to cover the connection between the spring sheets on both sides.

[0009] Furthermore, the upper surface of the key cap is a circular concave surface.

[0010] Furthermore, a plurality of anti-slip strips are provided on the upper surface of the key cap.

[0011] Furthermore, a triangular connecting column is provided on the sliding handle, which is vertically corresponding to the position of the triangular connecting hole at the lower end of the keycap.

[0012] In summary, the present application includes at least one of the following beneficial technical effects:

[0013] 1. When the keyboard is pressed, the sliding handle housed in the keyboard shaft housing slides downward, and the magnetic shaft located below the handle slides in the guide tube under pressure. When the magnetic shaft slides downward into the guide tube, the support spring located directly below the magnetic shaft is compressed. The spring pieces on both sides of the magnetic shaft and the spherical flanges on the spring pieces slide downward along the inner wall of the guide tube to reach the annular groove. The spherical flanges are engaged in the annular groove, causing the collision with the tube wall to produce a trigger sound. When the pressing force is withdrawn, the support spring rebounds upward and the magnetic shaft is rebounded to its original position. When the spring pieces on both sides of the magnetic shaft and the spherical flanges on the spring pieces pass through the annular groove again, the spherical flanges are engaged in the annular groove, producing a trigger sound effect. Under the elastic force of the support spring, the magnetic shaft continues to rebound upward, causing the magnetic shaft to reset, thereby improving the trigger sound effect of the mechanical keyboard.

[0014] 2. An inclined surface is provided at the opening of the guide tube. When the keyboard is pressed, the spherical flange on the spring sticks to the inner wall of the guide tube and slides downward because of the inclined surface at the opening of the guide tube, and will not get stuck at the opening of the guide tube, thereby improving the service life of the device.

[0015] 3. A limit spring is connected between the two springs and the magnetic axis. When the keyboard is pressed, the springs on both sides of the magnetic axis and the spherical flanges on the springs slide downward along the inner wall of the guide tube with the magnetic axis. The limit springs are compressed by the tube wall. The limit springs between the springs and the magnetic axis buffer the pressure on the springs in the guide tube, thereby extending the service life of the springs. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present application is further described in detail below in conjunction with the accompanying drawings.

[0026] Example, see Figures 1 to 7 A magnetic touch sensitive keyboard comprises a keyboard shaft housing 2, wherein the keyboard housing 2 comprises an upper cover 201 and a lower shell 202, wherein the upper cover 201 is fixedly installed with a buckle 203, and the lower shell 202 is fixedly installed with a slot 207, the buckle 203 and the slot 207 are buckled and assembled into the keyboard shaft housing 2, the upper end of the upper cover 201 is provided with a handle shift hole 206, a sliding handle 3 accommodated in the keyboard shaft housing 2, a triangular connecting column 301 is provided above the sliding handle 3, a shaft core 302 is provided below the sliding handle 3, a key cap 1 is connected above the sliding handle 3, the upper surface of the key cap 1 is a circular concave surface 102, and the key cap 1 A non-slip strip 101 is fixedly installed on the upper surface, a triangular connecting hole 103 is provided on the lower end surface of the keycap 1, a protective cover 5 is fixedly connected to the bottom of the sliding handle 3, the protective cover 5 is arranged above the magnetic axis 4, springs 6 are provided on both sides of the magnetic axis 4, spherical flanges 7 are respectively provided on the lower parts of the sides of the springs 6 on both sides, a limiting spring 8 is connected between the two springs 6 and the magnetic axis 4, the lower shell 202 is provided with a guide tube 205 perpendicular to the bottom of the lower shell 202, the inner wall of the guide tube 205 is provided with a circular groove 208, a support spring 9 located below the magnetic axis 4 is placed in the guide tube 205, and an inclined surface 2051 is provided at the opening of the guide tube 205.

[0027] When the keyboard is pressed, the magnetic axis 4 located below the sliding handle 3 slides into the guide tube 205 under pressure. When the magnetic axis 4 slides downward into the guide tube 205, the support spring 9 located directly below the magnetic axis 4 is compressed. The spring pieces 6 on both sides of the magnetic axis 4 and the spherical flanges 7 on the spring pieces 6 slide downward with the magnetic axis 4 along the inner wall of the guide tube 205 and reach the annular groove 208. The spherical flanges 7 are engaged in the annular groove 208, so that the collision with the tube wall produces a trigger sound. When the force applied to the keyboard is released, the support spring 9 rebounds upward and the magnetic axis 4 is rebounded to its original position. When the spring pieces 6 on both sides of the magnetic axis 4 and the spherical flanges 7 on the spring pieces 6 pass through the annular groove 208 again, the spherical flanges 7 are engaged in the annular groove 208, producing a trigger sound effect. Under the elastic force of the support spring 9, the magnetic axis 4 continues to rebound upward, so that the magnetic axis 4 is reset.

[0028] Reference Figure 1 as well as Figure 4 The lower shell 202 is provided with a guide tube 205 perpendicular to the bottom of the lower shell 202, and an inclined surface 2051 is provided at the opening of the guide tube 205. Because the opening of the guide tube 205 is the inclined surface 2051, the spherical flange 7 on the spring 6 slides downward against the inner wall of the guide tube 205 and is not easily stuck at the opening of the guide tube 205, so that the spherical flange 7 can smoothly enter the guide tube 205, thereby improving the use effect of the keyboard.

[0029] Reference Figure 1 , Figure 2 , Figure 6 as well as Figure 7 The triangular connecting column 301 passes through the handle displacement hole 206 of the upper cover 201 and is connected to the triangular connecting hole 103, so that the keycap 1 is installed on the sliding handle 3. When the keyboard is pressed, the sliding handle 3 accommodated in the keyboard shaft housing 2 slides downward, and the lower end of the sliding handle 3 is fixedly installed with the shaft core 302. The lower end of the sliding handle 3 is fixedly connected with the shaft core 302. The protective cover 5 is arranged above the magnetic axis 4 to cover the connection between the two side springs 6, so that the springs 6 are not damaged by the pressure from the magnetic core, thereby extending the service life of the springs 6.

[0030] Reference Figure 1 as well as Figure 2 The limit spring 8 is connected between the magnetic axis 4 and the spring 6, which limits the distance between the far end of the spring 6 and the magnetic axis 4, so that the straight-line distance between the end points of the spherical flange 7 is smaller than the diameter of the opening of the guide tube 205, so that the spherical flange 7 can smoothly enter the guide tube 205 when the keyboard is pressed. The springs 6 on both sides of the magnetic axis 4 and the spherical flange 7 on the spring 6 follow the magnetic axis 4 and slide downward along the inner wall of the guide tube 205 through the annular groove 208, and collide with the tube wall to produce a trigger sound. The keyboard can produce a trigger sound when in use, thereby achieving the purpose of improving the keyboard usage effect.

[0031] Reference Figure 1 , Figure 3 as well as Figure 4 A vertically placed support spring 9 is installed inside the guide tube 205, and the support spring 9 corresponds vertically to the position of the magnetic axis 4. When the keyboard is pressed, the magnetic axis 4 slides downward into the guide tube 205, and the support spring 9 directly below the magnetic axis 4 is compressed. When the force applied to the keyboard is released, the support spring 9 rebounds upward and the magnetic axis 4 is rebounded to its original position. The sliding handle 3 above the magnetic axis 4 rebounds to its original position with the magnetic axis 4. When the spring pieces 6 on both sides of the magnetic axis 4 and the spherical flange 7 on the spring pieces 6 reach the annular groove 208 again, the spherical flange 7 is engaged in the annular groove 208 to produce a trigger sound effect. Under the elastic force of the support spring 9, the magnetic axis 4 continues to rebound upward, so that the magnetic axis 4 is reset.

[0032] Reference Figure 5 When using the keyboard, the circular concave surface 102 on the upper surface of the keycap 1 fits the arc shape of human fingers better, making the keyboard feel better. A plurality of anti-slip strips 101 are fixedly installed on the upper surface of the keycap 1. The anti-slip strips 101 are transparent. The transparent anti-slip strips 101 will not cover or affect the display effect of letters and symbols on the keycap 1. The anti-slip strips 101 increase the friction of the keycap 1 surface, and have an anti-slip effect when using the keyboard.

[0033] Working principle:

[0034] When the keyboard is pressed, the keycap 1 is subjected to downward pressure, so that the sliding handle 3 connected to the keycap 1 is subjected to downward pressure and slides downward, the protective cover 5 fixedly connected to the shaft core 302 at the lower end of the sliding handle 3 and the magnetic shaft 4 arranged below the protective cover 5 slide downward, the springs 6 on both sides of the magnetic shaft 4 and the spherical flanges 7 on the springs 6 slide downward with the magnetic shaft 4 against the inner wall of the guide tube 205, the limit springs 8 connected to the magnetic shaft 4 and the springs 6 on both sides of the magnetic shaft 4 are compressed by the tube wall, and the limit springs 8 between the springs 6 and the magnetic shaft 4 buffer the pressure on the springs 6 in the guide tube 205, because the opening of the guide tube 205 is the inclined surface 2051, the spherical flange 7 and the straight-line distance between the two spherical flanges 7 end points are less than the inner wall diameter of the guide tube 205, so the two spherical flanges 7 can slide smoothly downward into the guide tube 205. When the magnetic shaft 4 slides into the guide tube 205 and reaches the position of the support spring 9, the support spring located in the guide tube 205 is compressed. When the spring pieces 6 on both sides of the magnetic shaft 4 and the spherical flanges 7 on the spring pieces 6 slide downward along the inner wall of the guide tube 205 and reach the annular groove 208 , the spherical flanges 7 are engaged in the annular groove 208 .

[0035] When the force applied to the keyboard is released, the support spring 9 rebounds upward and the magnetic axis 4 is rebounded back to its original position. When the spring pieces 6 on both sides of the magnetic axis 4 and the spherical flanges 7 on the spring pieces 6 pass through the annular groove 208 again, the spherical flanges 7 are engaged in the annular groove 208 to produce a trigger sound effect. Under the elastic force of the support spring 9, the magnetic axis 4 continues to rebound upward, so that the magnetic axis 4 is reset.

[0036] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
