Description

Technical Field

[0001] The invention relates to a key axis of a mechanical keyboard, in particular to a key axis of a mechanical keyboard which can be switched between a paragraph axis and a linear axis. Background Art

[0002] In the context of office peripheral upgrades, the demand standards of many digital devices are gradually upgraded, and keyboards are one of them. Mechanical keyboards are widely used in scenarios such as typing, programming, and gaming due to their excellent feel and durability. However, existing mechanical keyboards usually use a single type of key axis, which cannot meet the diverse needs of users in different scenarios. For example, the paragraph axis is suitable for typing and playing games, but it may not be suitable for public places because of the loud noise; the linear axis is suitable for office work in public places, but because there is no sound and feel feedback, it may lack tactile feedback when typing. Therefore, a mechanical keyboard with a single axis cannot meet the user's usage needs in diverse scenarios, limiting the improvement of user experience. Summary of the invention

[0003] The purpose of the present invention is to provide a dual-axis conversion mechanical keyboard, which can realize free conversion of the keyboard between the paragraph axis and the linear axis through a unique design.

[0004] In order to achieve the technical purpose of the present invention, the following design scheme will be adopted: An integrated dual-axis conversion key shaft includes a protection groove, a rotation lock, an upper serrated tip, a spring base, a pressure push rod, an axis column, and a lower serrated gear. The pressure push rod is connected to the upper serrated tip, and the pressure push rod is in the protection groove so that it will not be affected by the top key cap. The axis column is connected to the lower serrated gear, the axis column is inserted into the bottom hole of the upper serrated tip, the bottom hole of the lower serrated gear is inserted on the spring base and fixed, and the rotation lock is fixed on one side of the inclined surface of the shell, with the long side facing the lower serrated gear and the short side attached to the inclined surface of the shell.

[0005] Based on the above technical solution, the axis column is connected to the upper serrated tip, the pressure push rod, and the lower serrated gear. There are eight side columns on the side of the upper serrated tip, and each side column has a triangular prism-shaped serrated tip at the bottom. There is a groove between each side column, and the width is the same as the width of the side column. There is a hole at the bottom of the upper serrated tip, and the depth is the same as the length of the axis column, which is used for linear rotation and preventing the lower serrated gear and the upper serrated tip from always remaining in place. There are 8 side columns on the side of the lower serrated gear, and there is a serrated tip on the upper end of the side column. There is a groove between each side column, and the groove is the same width as the side column. The lower serrated gear is fixedly connected to the axis column.

[0006] Based on the above technical solution, the cylinder in the middle of the rotary lock is the rotation point, which is fixed inside the inclined surface of the key shaft shell. The short end of the rotary lock is controlled to move up and down by the force on the long end of the rotary lock. The groove width between the long end of the rotary lock and the side column of the serrated gear at the lower end is the same. The outer periphery of the side column of the serrated gear at the lower end is in the form of a ladder column, so that the long end of the rotary lock can slide in and out to achieve the change of force applied to the long end of the rotary lock. There is a rectangular hole on the inclined surface, which is slightly larger than the short end of the rotary lock, so that the short end of the rotary lock can be rotated out and restored.

[0007] Based on the above technical solution, there is a circular hole in the middle of the protective groove with a radius slightly larger than the radius of the pressure push rod. The pressure push rod passes through the protective groove. The height of the pressure push rod is lower than the depth of the protective groove. The pressure push rod is fixedly connected to the serrated tip at the upper end.

[0008] Based on the above technical solution, there is a fixed cylinder at the upper end of the spring base, and there is a hole at the lower end of the serrated gear at the lower end fixedly connected to the axial column, the radius of which is slightly lower than the radius of the fixed cylinder at the upper end of the spring base, and the hole at the lower end of the serrated gear at the lower end fixedly connected to the axial column is inserted into the fixed cylinder at the upper end of the spring base for linear rotation.

[0009] Compared with the existing traditional single-axis mechanical keyboard, the present invention can drive the lower end serrated gear to rotate and push the rotary lock out by pressing the pressure push rod, so that the inclined surface of the mechanical keyboard changes from linear to paragraph. The changing method is simple and convenient, and the conversion between the linear axis and the paragraph axis can be realized without removing the axis, which meets the application needs of keyboard users in different usage scenarios. The keyboard touch feel can be changed at will, and the ratio of the paragraph axis to the linear axis in the keyboard can be adjusted in a personalized manner. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] like Figure 1-6 As shown, an integrated double-axis conversion key shaft includes: a protective groove 1, a rotary lock 2, an upper serrated tip 3, a spring base 4, a pressure push rod 5, an axis column 6, and a lower serrated gear 7, characterized in that: the pressure push rod 5 is connected to the upper serrated tip 3, and the pressure push rod 5 is in the protective groove 1 so that it will not be affected by the top keycap; the axis column 6 is connected to the lower serrated gear 7, the axis column 6 is inserted into the bottom hole of the upper serrated tip 3, and the bottom hole of the lower serrated gear 7 is inserted on the spring base 4 and fixed; the rotary lock 2 is fixed to one side of the inclined surface of the outer shell, with the long side facing the lower serrated gear 7 and the short side attached to the inclined surface of the outer shell.

[0019] The axis column 6 is connected to the upper serrated tip 3, the pressure push rod 5, and the lower serrated gear 7. The upper serrated tip 3 has eight side columns on its side, and each side column has a triangular prism-shaped serrated tip at the bottom. There is a groove between each side column, and the width is the same as the width of the side column. There is a hole at the bottom of the upper serrated tip 3, and the depth is the same as the length of the axis column 6, which is used for linear rotation and preventing the lower serrated gear 7 and the upper serrated tip 3 from always remaining in place. There are eight side columns on the side of the lower serrated gear 7, and the upper end of the side column has a serrated tip. There is a groove between each side column, and the groove is the same as the width of the side column. The lower serrated gear 7 is fixedly connected to the axis column 6.

[0020] The cylinder in the middle of the rotary lock 2 is the rotating part, which is fixed inside the inclined surface of the key shaft shell. The short end of the rotary lock 2 is controlled to move up and down by the force on the long end of the rotary lock 2. The groove width between the long end of the rotary lock 2 and the side column of the serrated gear 7 at the lower end is the same. The outer periphery of the side column of the serrated gear 7 at the lower end is in a trapezoidal column shape, so that the long end of the rotary lock 2 can slide in and out to achieve the change of the force applied to the long end of the rotary lock 2. There is a rectangular hole on the inclined surface, which is slightly larger than the short end of the rotary lock 2, so that the short end of the rotary lock 2 can be rotated out and restored.

[0021] There is a circular hole in the middle of the protection groove 1, the radius of which is slightly larger than the radius of the pressure push rod 5. The pressure push rod 5 passes through the protection groove 1. The height of the pressure push rod 5 is lower than the depth of the protection groove 1. The pressure push rod 5 is fixedly connected to the serrated tip 3 at the upper end.

[0022] The upper end of the spring base 4 is provided with a fixed cylinder, and the lower end of the serrated gear 7 fixedly connected to the axial column 6 has a hole at the lower end, the radius of which is slightly lower than the radius of the fixed cylinder at the upper end of the spring base 4, and the lower end hole of the serrated gear 7 fixedly connected to the axial column 6 is inserted into the fixed cylinder at the upper end of the spring base 4 for linear rotation.

[0023] The working principle of the present invention is as follows: the key shaft is embedded into the keyboard, and the key cap is installed above the protective shell of the shaft. Because the protective groove 1 protects the pressure push rod 5, pressing the keyboard will not affect the normal operation of the key shaft. However, when the shaft type needs to be replaced, only the key cap needs to be pulled off, and no tool is needed to remove the key shaft. The pressure push rod 5 is pressed down, and the upper serrated tip 3 will squeeze the lower serrated gear 7, and the lower serrated gear 7 will continue to press down the spring base 4. The spring compression ring will rotate to drive the base to rotate. The lower serrated gear 7 is connected to the base and will rotate simultaneously due to the downward pressure of the spring. At this time, the internal sharp tooth structure of the lower serrated gear 7 will make the lower serrated gear 7 rotate unidirectionally in the counterclockwise direction and will not be reset due to the spring rebound. The tip of the upper serrated tip 3 plays a thrust role, making the rotation of the lower serrated gear 7 smoother. The shaft core column 6 will protect the lower serrated gear 7 from deviation. When the serrated gear 7 at the lower end is pressed down again, it will rotate once, and the side column will rotate synchronously once, and the long end of the rotary lock 2 will slide out along the trapezoidal inclined surface, and the keyboard trigger paddle will slide over it to produce a paragraph-like feel; when the serrated gear 7 at the lower end is pressed down again, it will rotate once, and the side column will rotate synchronously once, and the long end of the rotary lock 2 will slide out along the trapezoidal inclined surface, and the rotary lock 2 will have no force point and will droop and return to its original position, and the trapezoidal surface at the short end will return to its original position synchronously, and the inclined surface of the outer shell will change from paragraph-like to smooth and linear, and the keyboard metal paddle will be converted into a linear feel when it passes over it.

[0024] The above is a preferred implementation scheme of the present invention. For ordinary technical personnel and practitioners related to the field, based on the inspiration of the present invention, without departing from the principle and spirit of the present invention, the modifications, replacements and conversions made in its implementation and application methods still fall within the scope of protection of the present invention.
