Description

Technical Field

[0001] The utility model relates to the technical field of keyboards, in particular to a satellite axis component on a keyboard. Background Art

[0002] Satellite switches are generally used on larger or longer keys on the keyboard, such as the space bar and shift key. They are used to balance the keys to ensure that the keys will not lift or deflect when the fingers press on different positions of the keys and can produce the same pressing effect.

[0003] Currently, most satellite key mechanisms are designed to consist of two key cores and a connecting rod between them. The two cores support the keycaps, and the connecting rod creates a linkage effect between the two cores to ensure a pressing effect. However, during assembly, the process of embedding the connecting rod into the core is time-consuming and labor-intensive, and it is easy to break the connecting rod or damage the core. The tightness of the connection between the connecting rod and the core directly affects the key's pressing feel and noise. Utility Model Content

[0004] In response to the problems existing in the above-mentioned prior art, the utility model provides a satellite shaft assembly on the keyboard, which can reduce the downward thrust on the torsion spring when pressing the shaft core, thereby reducing the impact force of the torsion spring as a whole on the keyboard, reducing key noise, and improving the operator's operating feel. There is no need to distinguish between left and right directions during the production and assembly process, which is convenient for production and assembly and has low cost.

[0005] In order to solve the above technical problems, a technical solution adopted by the present invention is as follows:

[0006] A satellite shaft assembly for a keyboard comprises two shaft cores arranged horizontally along the X direction and a torsion spring connected therebetween; each shaft core is slidably mounted on a shaft sleeve, and the torsion spring is mounted on the two shaft sleeves with both ends extending to one shaft core respectively; wherein:

[0007] Each of the shaft sleeves is provided with a slideway and a mounting channel that are interconnected, each of the slideways extends along the Z direction, and each of the mounting channels extends along the X direction;

[0008] Each of the shaft cores includes a body and a buffer embedded therein, each of the bodies is slidably mounted on one of the slideways, and each of the buffers is formed with a cavity;

[0009] The middle part of the torsion spring is matched and mounted on the two mounting channels, and its two ends respectively pass through one of the bodies and extend into one of the cavities; pressing each of the bodies to slide along the Z direction in one of the slideways can drive the buffer part thereon to move synchronously, and cause it to push one end of the torsion spring to drive the entire torsion spring to flip.

[0010] As a further elaboration of the above technical solution:

[0011] In the above technical solution, each of the shaft sleeves is further provided with an avoidance channel extending in the Y direction, one end of which is connected to the cavity, and the other end of which is connected to the installation channel.

[0012] In the above technical solution, each of the installation channels includes two arc-shaped installation grooves provided at one end of each shaft sleeve and arranged along the X direction, and the avoidance channel is provided in the middle of the two arc-shaped installation grooves.

[0013] In the above technical solution, each of the slideways is a hole groove provided in the middle of each sleeve and passing through the sleeve along the Z direction. Each of the hole grooves is provided with one or more protrusions on the inner wall, and several of the protrusions and part of the side wall of the hole groove together form a cavity that can accommodate the body.

[0014] In the above technical solution, each of the shaft sleeves is provided with one or more positioning structures on both sides of the shaft core in the Y direction.

[0015] In the above technical solution, each of the main bodies is a hard body, and each of the buffer components is a flexible rubber pad.

[0016] In the above technical solution, each of the main bodies includes a cross pressing part and a transmission part arranged in the Z direction, and each of the transmission parts is a frame-shaped structure, and its Y-direction side wall facing the torsion spring is an open end; a buffer part is embedded on the side wall of each of the transmission parts, and the inner wall of the cavity on each of the buffer parts that contacts the torsion spring is a slope.

[0017] In the above technical solution, a safety window is further provided on the bottom wall of each of the main bodies away from the cross pressing portion, and the safety window is communicated with the cavity.

[0018] In the above technical solution, the main body and the buffer member on each shaft core are an integrally formed structure.

[0019] Compared with the prior art, the beneficial effects of the present invention are: by installing a buffer part on the contact surface of the shaft core and the torsion spring, the downward thrust on the torsion spring when pressing the shaft core can be reduced, thereby reducing the impact force of the torsion spring as a whole on the keyboard, reducing the key noise, and due to the rebound of the buffer part, the operator's operating feel can be improved; by arranging two arc-shaped mounting grooves arranged along the extension direction of the torsion spring on the shaft sleeve, the shaft sleeves that can respectively fix the left and right sides of the torsion spring can have the same structure, and there is no need to distinguish between the left and right directions during the production and assembly of the shaft sleeves, which is convenient for production and assembly, and has low cost.

[0026] like Figure 1-3As shown, a satellite shaft assembly on a keyboard includes two shaft cores 10 arranged horizontally along the X direction and a torsion spring 20 connected therebetween. Each shaft core 10 is slidably mounted on a shaft sleeve 30. The torsion spring 20 is mounted on the two shaft sleeves 30 and its two ends extend to one shaft core 10 respectively. Each shaft sleeve 30 is provided with a slideway 31 and a mounting channel 32 that are interconnected. Each slideway 31 extends along the Z direction, and each mounting channel 32 extends along the X direction. Each shaft core 10 includes a body 11 and the buffer member 12 embedded therein, each body 11 is slidably mounted on a slide 31, and a cavity 121 is formed on each buffer member 12; the middle part of the torsion spring 20 is matched and mounted on the two mounting channels 32, and its two ends respectively pass through a body 11 and extend into a cavity 121; pressing each body 11 to slide along the Z direction in a slide 31 can drive the buffer member 12 thereon to move synchronously, and cause it to push one end of the torsion spring 20 to drive the entire torsion spring 20 to flip.

[0027] like Figure 2 As shown, in this embodiment, each sleeve 30 is also provided with an avoidance channel 33 extending in the Y direction, one end of which is connected to the cavity 121, and the other end is connected to the installation channel 32; each installation channel 32 includes two arc-shaped installation grooves 321 arranged at one end of each sleeve 30 and arranged along the X direction, and an avoidance channel 33 is provided in the middle of the two arc-shaped installation grooves 321; each slide 31 is a hole groove provided in the middle of each sleeve 30 and passing through the sleeve 30 along the Z direction, and each hole groove is provided with one or more protrusions 311 on the inner wall, and several protrusions 311 and part of the side wall of the hole groove together form a cavity that can accommodate the body 11; each sleeve 30 is provided with one or more positioning structures 34 on both sides of the shaft core 10 in the Y direction.

[0028] It can be understood that the protrusion 311 can form a gap between the main body 11 and the sleeve 30, thereby preventing the main body 11 from being pressed and forming a vacuum between the main body 11 and the sleeve 30 during the sliding process of the slide 31, ensuring a smooth pressing operation; the two arc-shaped mounting grooves 321 symmetrically arranged along the X direction at one end of the sleeve 30 can make the sleeves 30 that can respectively fix the left and right sides of the torsion spring 20 have the same structure, and there is no need to distinguish between the left and right directions during the production and assembly of the sleeve 30, which is convenient for production and assembly and has low cost; the mounting groove 34 facilitates fixing the sleeve 30 and the satellite axis assembly in the appropriate place in the keyboard, and is easy to install.

[0029] like Figure 3As shown, in this embodiment, each main body 11 includes a cross pressing portion 111 and a transmission portion 112 arranged in the Z direction, and each transmission portion 112 is a frame-shaped structure, and its Y-direction side wall facing the torsion spring 20 is an open end; a buffer part 12 is embedded in the side wall of each transmission part 112, and the inner wall of the cavity 121 on each buffer part 12 that contacts the torsion spring 20 is an inclined surface; a safety window 113 is also provided on the bottom wall of each main body 11 away from the cross pressing portion 111, and the safety window 113 is connected to the cavity 121.

[0030] It is understood that after the shaft core 10, the torsion spring 20 and the sleeve 30 are assembled, the operator can view the matching condition between the buffer 12 and the end of the torsion spring 20 through the safety window 113, and can easily insert the buffer 12 from here when there is an abnormality such as a jam between the two.

[0031] In this embodiment, each body 11 is rigid, and each buffer 12 is a flexible rubber pad. The body 11 and buffer 12 on each shaft core 10 are integrally molded. During production, the shaft core 10 is formed using a two-shot injection molding process: the body 11 is formed from solidified ABS glue, and the buffer 12 is formed from solidified TPE glue. This allows the shaft core 10 to be molded using a single mold, eliminating the need for subsequent assembly. This results in high efficiency, stable quality, and relatively low manufacturing costs.

[0032] The present invention installs a buffer member 12 on the contact surface between the shaft core 10 and the torsion spring 20, which can reduce the downward thrust of the torsion spring 20 when the shaft core 10 is pressed, thereby reducing the impact force of the torsion spring 20 on the keyboard as a whole, reducing keystroke noise, and the rebound of the buffer member 12 can improve the operator's operating feel.

[0033] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
