[0036] The following is in conjunction with the appendix Figures 1-6 The present invention will be described in further detail, but this is not intended to limit the scope of the present invention.

[0037] like Figure 1 and 2 As shown, in one embodiment of this utility model, the satellite axis structure includes a balance bar 1, a bearing seat 2, a shaft body 3, and a fastener 4. The shaft body 3 is movably disposed inside the bearing seat 2. A locking part 11 is provided on one side end of the balance bar 1. The locking part 11 extends into the bearing seat 2 and the shaft body 3 in sequence and is movably connected to the shaft body 3. A protrusion 21 is provided on the bearing seat 2. The protrusion 21 is provided with an interconnected mounting hole 201 and a mounting groove 202. The fastener 4 is connected to the inside of the mounting groove 202.

[0038] The technical solution of this utility model uses a protrusion to position the switch seat, and combines this with the fastening action of the fasteners to ensure that the switch seat is assembled into the corresponding position on the keyboard's internal positioning plate or circuit board, preventing the switch seat from loosening or shifting during use; thus improving the stability of use. In addition, the balance bar and its locking part provide a double limiting effect on the switch body to prevent the switch body from falling off or jamming during use; thus improving the stability of use.

[0039] Among them, such as Figure 1 and 5 As shown, the mounting hole 201 is located below the mounting groove 202; and the width L3 of the mounting groove 202 is greater than the inner diameter L4 of the mounting hole 201. That is, the mounting hole 201 and the mounting groove 202 form a T-shaped cavity; this allows the fastener 4 and the protrusion 21 to be separately positioned, thus eliminating the need for injection molding to connect the fastener 4 and the bearing 2, effectively reducing production costs and improving production efficiency. Simultaneously, the separate positioning of the fastener 4 and the protrusion makes the bearing 2 easier to install and remove. When the bearing 2 needs to be replaced or repaired, it can be easily removed simply by removing the fastener 4, without damaging the injection mold or the entire button structure, thereby reducing maintenance costs and difficulty.

[0040] Specifically, in some implementations, such as Figure 1 and 2As shown, the fastener 4 includes a fastening post 41; the fastening post 41 is connected to the mounting groove 202; and the fastening post 41 has a fastening through hole 412; one end of the fastening through hole 412 is connected to one end of the mounting hole 201; the other end of the mounting hole 201 away from the fastening through hole 412 is connected to the outside of the bottom direction of the bearing 2; the other end of the fastening through hole 412 away from the mounting hole 201 is connected to the outside of the top direction of the bearing 2. The fastening through hole 412 can be a smooth inner hole or a threaded hole with a threaded inner surface (a rivet is installed in the smooth hole; a screw is installed in the threaded hole); to improve the ease of assembly and disassembly of the fastener 4 and the bearing 2. Further, as... Figure 2 As shown, the fastening column 41 has at least one arc-shaped protrusion 411 on the outer surface facing the mounting groove 202; the arc-shaped protrusion 411 abuts against the inner wall (recess) of the mounting groove 202; to prevent the fastener 4 from loosening or shifting; thereby improving the stability of use.

[0041] Specifically, in some implementations, such as Figure 1 , 2 As shown in Figure 3, the locking part 11 includes a locking horizontal section 111; the balance bar 1 includes a support part 12; one end of the support part 12 passes through the bearing seat 2 and the shaft body 3, and is disposed with respect to one side end of the locking horizontal section 111; the bottom of the shaft body 3 is provided with a limiting groove 301; the other side end of the locking horizontal section 111 extends toward the limiting groove 301 and is movably connected to the inside of the limiting groove 301. Wherein, as... Figure 3 As shown, each end of the support portion 12 has a locking horizontal section 111. That is, one end of the support portion 12 in the balance bar 1 is inserted into the corresponding shaft 3 from one side of the bearing seat 2. When the shaft 3 moves downward, the shaft 3 and its limiting groove 301 will cause the corresponding end of the locking horizontal section 111 to press downward and slide along the inner wall of the limiting groove 301; simultaneously, the support portion 12 will rotate accordingly, and the other end of the support portion 12 will perform the same action. When the shaft 3 moves upward, the shaft 3 and its limiting groove 301 will cause the corresponding end of the locking horizontal section 111 to tilt upward and slide along the inner wall of the limiting groove 301; simultaneously, the support portion 12 will rotate accordingly, and the other end of the support portion 12 will perform the same action. Therefore, this structure ensures that the button maintains a balanced state when pressed, improving the stability of button operation.

[0042] In some implementation methods, such as Figure 3As shown, the support portion 12 includes a horizontal mounting section 122 and a longitudinal mounting section 121. One end of the horizontal mounting section 122 is connected to one end of the longitudinal mounting section 121. The other end of the longitudinal mounting section 121 passes through the bearing seat 2 and the shaft body 3 in sequence and is connected to the locking horizontal section 111. Further, there are two longitudinal mounting sections 121. One end of the longitudinal mounting section 121 is connected to one end of the horizontal mounting section 122. The other end of the longitudinal mounting section 121 passes through one bearing seat 2 and one shaft body 3 in sequence and is connected to one locking horizontal section 111. The other end of the horizontal mounting section 122, away from the longitudinal mounting section 121, is connected to one end of the other longitudinal mounting section 121. The other end of the other longitudinal mounting section 121 passes through another bearing seat 2 and another shaft body 3 in sequence and is connected to another locking horizontal section 111. In other words, the locking horizontal section 111 and the installation longitudinal section 121 form a first L-shaped structure; the installation horizontal section 122 and the installation longitudinal section 121 form a second L-shaped structure; thereby avoiding the phenomenon of misalignment or detachment of the shaft 3 in the front-back or left-right directions, and thus improving the stability of use.

[0043] Specifically, in some implementations, such as Figure 2 As shown, the bottom of the shaft 3 is also provided with a movable groove 302; the movable groove 302 is connected to the limiting groove 301; and one end of the support part 12 (with the longitudinal section 121 installed in it) is movably disposed inside the movable groove 302. That is, when the shaft 3 moves downward, the shaft 3 and its limiting groove 301 will drive the corresponding end of the locking horizontal section 111 to press downward, while the longitudinal section 121 moves to the side along the inside of the movable groove 302 (e.g., Figure 1 and 2 As shown, the side is the front side in the Y-axis direction; and the locking horizontal section 111 slides along the inner wall of the limiting groove 301; at the same time, the support part 12 will rotate accordingly, and the other end of the support part 12 will move in the same way. When the shaft 3 moves upward, the shaft 3 and its limiting groove 301 will cause the corresponding end of the locking horizontal section 111 to tilt upward, while the mounting longitudinal section 121 moves along the inside of the movable groove 302 towards the side (e.g., the front side in the Y-axis direction); and the locking horizontal section 111 slides along the inner wall of the limiting groove 301; at the same time, ... inner wall of the limiting groove 302 towards the side). Figure 1 and 2 As shown, the side is the rear side in the Y-axis direction; and the locking horizontal section 111 slides along the inner wall of the limiting groove 301; at the same time, the support part 12 will make a corresponding rotational movement, and the other end of the support part 12 will produce the same action in conjunction.

[0044] Specifically, in some implementations, such as Figure 2 and 4As shown, the bottom of the shaft 3 is also provided with an abutment groove 303; the abutment groove 303 is connected to the limiting groove 301; the abutment groove 303 and the movable groove 302 are arranged opposite to each other on both sides of the limiting groove 301; the side end of the locking horizontal section 111 away from the support part 12 abuts against the inner wall of the abutment groove 303; and the width L2 of the limiting groove 301 is smaller than the width L1 of the abutment groove 303. That is to say, the abutment groove 303 and the limiting groove 301 form a T-shaped stepped groove; and through the abutment support of the locking horizontal section 111 by the abutment groove 303, the friction scratches caused by the upward or downward movement of the locking horizontal section 111 are reduced; thereby improving the stability of use.

[0045] Specifically, in some implementations, such as Figure 1 , 2 As shown in Figure 4, the shaft 3 includes a pressing part 31 and a connecting part 32 that are stacked and connected; an abutment groove 303 and a limiting groove 301 are disposed inside the connecting part 32; the movable groove 302 is formed between the pressing part 31 and the connecting part 32; this effectively reduces the weight of the shaft 3 and ensures its stability and flexibility of movement. Wherein, as Figure 4 As shown, the connecting part 32 includes a first vertical connecting block 322, a horizontal connecting block 321, and a second vertical connecting block 323 connected in sequence; the side of the first vertical connecting block 322 away from the horizontal connecting block 321 is connected to the bottom of the pressing part 31; the side of the second vertical connecting block 323 away from the horizontal connecting block 321 is connected to the bottom of the pressing part 31; and the abutment groove 303 and the limiting groove 301 are formed between the first vertical connecting block 322, the horizontal connecting block 321, the second vertical connecting block 323, and the pressing part 31. This structure, through the U-shaped limiting structure formed by the first vertical connecting block 322, the horizontal connecting block 321, and the second vertical connecting block 323, ensures the flexibility of movement and the assembly stability of the locking part 11.

[0046] Specifically, in some implementations, such as Figure 1 and 2As shown, the bearing seat 2 includes a main body 22, a mounting side 23, and a limiting component 24. The mounting side 23 is connected to one side surface of the main body 22. A protrusion 21 is provided on the mounting side 23. The limiting component 24 is connected to the other side surface of the main body 22. A movable channel 204 is provided inside the main body 22. The movable channel 204 extends through the height of the main body 22. An assembly channel 203 communicating with the movable channel 204 is provided on the side end face of the main body 22. The shaft 3 is movably connected to the interior of the movable channel 204. One end of the balance bar 1 passes through the limiting component 24 and the assembly channel 203, and extends into the interior of the movable channel 204. The outer surface of the balance bar 1 is movably connected to the limiting component 24. One end of the longitudinal mounting section 121 passes through the assembly channel 203 and extends into the interior of the movable channel 204. The horizontal mounting section 122 is rotatably connected to the interior of the limiting component 24. The structure ensures the stability of the balance bar 1's movement and prevents it from falling off by limiting the rotation of the horizontal section 122 through the limiting component 24 and limiting the rotation and movement of the longitudinal section 121 through the assembly channel 203.

[0047] In some implementation methods, such as Figure 1 and 5 As shown, the protrusion 21 is a columnar protrusion that extends through the height of the mounting side 23; or there are two columnar protrusions, which are positioned opposite each other on the upper and lower surfaces of the mounting side 23. This structure enhances the stability of the entire structure. This helps prevent the bearing 2 from loosening or shifting due to vibration or external forces during use.

[0048] Specifically, in some implementations, such as Figure 2 and 5As shown, the limiting assembly 24 includes a first limiting block 241 and a second limiting block 242 arranged side by side; one side of the first limiting block 241 and one side of the second limiting block 242 are respectively connected to the main body 22; and a guide cavity 243, a limiting cavity 244, and a buffer cavity 245 are sequentially connected between the first limiting block 241 and the second limiting block 242; the inner diameter of the opening of the limiting cavity 244 is larger than the inner diameter of the opening of the guide cavity 243; the inner diameter of the opening of the guide cavity 243 is larger than the inner diameter of the opening of the buffer cavity 245. That is to say, the outer surface of the mounting horizontal section 122 in the balance bar 1 passes through the guide cavity 243 along the opening of the guide cavity 243 and enters the inner wall of the limiting cavity 244; thereby, it can stably rotate inside the limiting cavity 244; thus improving the stability of use. In addition, in order to accommodate the installation horizontal section 122 in the balance bar 1 with a certain reasonable inner diameter, when the installation horizontal section 122 in the balance bar 1 with a larger size enters the limiting cavity 244, the buffer cavity 245 will be slightly enlarged, and the squeezing and limiting effect on the installation horizontal section 122 in the balance bar 1 will be improved, thereby improving the adaptability and stability of use.

[0049] Specifically, in some implementations, such as Figure 5 and 6 As shown, the inner wall of the guide cavity 243 is provided with a guide straight surface 248 and a guide inclined surface 249 connected in sequence; the inner wall of the limiting cavity 244 is provided with a limiting arc surface 246; the inner wall of the buffer cavity 245 is provided with a buffer straight surface 247; and the buffer straight surface 247 is connected to one end of the limiting arc surface 246; the other end of the limiting arc surface 246 is connected to the guide straight surface 248. This structure can improve the assembly smoothness and stability of the mounting horizontal section 122 in the balance bar 1, thereby improving the stability of use. That is, the guide straight surface 248, the guide inclined surface 249, the limiting arc surface 246, and the buffer straight surface 247 are all provided on the surfaces of the first limiting block 241 and the second limiting block 242, respectively.

[0050] Specifically, in some implementations, such as Figure 5 and 6 As shown, the second limiting block 242 has a positioning post 26 and a positioning hook block 27 on the side surface away from the first limiting block 241. The positioning post 26 is a cylindrical block; the positioning hook block 27 is an L-shaped positioning block, in order to further improve the positioning efficiency.

Since this button adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0052] The key assembly includes a circuit board, a mounting plate, a mechanical spindle, keycaps, and a stabilizer structure. The mounting plate is positioned above the circuit board at intervals. The mechanical spindle is mounted on the mounting plate and electrically connected to the circuit board. The keycaps are movably mounted on the mounting plate via the mechanical spindle, and the left and right ends of the bottom of the keycaps are connected to the upper ends of the stabilizer structure. The circuit board model can be 100629 or JP69321, etc.

[0053] Understandably, this satellite axis structure is used to support the keyboard keycaps, improving the balance of keycap installation. It is especially suitable for supporting longer keycaps, such as the "Shift" key, "Space" key, and "Enter" keycaps, so that they can maintain left and right balance when connected to their respective mechanical spindles. This allows the keycaps to be pressed down smoothly from any position when pressed, and to rebound smoothly after being pressed.
