Description

Technical Field

[0001] This utility model relates to the field of mechanical keyboard technology, and in particular to a keyboard stabilizer and a mechanical keyboard. Background Technology

[0002] Keyboard stabilizers (or simply stabilizers) are components in mechanical keyboards used to stabilize long keys (such as the spacebar, Enter key, and Shift key). They ensure that long keys are balanced when pressed, preventing a "seesaw effect." Specifically, when a user presses a long key on a mechanical keyboard, the keycap sinks under pressure, causing the stabilizer's pseudo-axis to move downwards and press against a steel wire. The rotating steel wire distributes the pressure evenly to both ends of the keycap, thus avoiding the problem of the keycap tilting due to one-sided force (i.e., the seesaw effect). However, in this process, the downward movement of the pseudo-axis and its contact with the steel wire produces considerable noise (wire noise), which can affect the user experience.

[0003] In response to this, existing technology has developed a satellite axis with a soft rubber sleeve fitted on a steel wire (where the end of the steel wire fitted with the soft rubber sleeve passes through the through hole of the dummy axis, and the top and bottom walls of the through hole abut against the soft rubber sleeve to reduce noise when the dummy axis moves downward). However, the inventors found the following problems with the above-mentioned satellite axis in actual production testing: 1. The damping sensation provided by the soft rubber sleeve is relatively heavy, which affects the user's experience when pressing long keys; 2. When the dummy axis moves downward and presses against the soft rubber sleeve on the steel wire, the tightly fitted soft rubber sleeve suffers greater wear, which affects the service life of the soft rubber sleeve. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a keyboard stabilizer.

[0005] This invention also proposes a mechanical keyboard with the keyboard satellite axis.

[0006] According to a first aspect of the present invention, a keyboard stabilizer includes a base, a dummy switch, and a steel wire. Two bases are arranged side-by-side, and two dummy switches are slidably disposed on the two bases. Each dummy switch has a through hole. The steel wire is rotatably disposed on the base, with its two ends passing through the two through holes. Both ends of the steel wire have a hard plastic component. One of the top and bottom walls of the through hole abuts against the corresponding hard plastic component, while the other has a gap with the corresponding hard plastic component. One of the dummy switches can slide to abut against the corresponding hard plastic component, causing the steel wire to rotate and drive the other dummy switch to slide synchronously.

[0007] A keyboard stabilizer according to an embodiment of the present invention has at least the following beneficial effects:

[0008] When a long key of a mechanical keyboard equipped with the keyboard stabilizer of this application is pressed, the keycap sinks under pressure, causing the dummy axis to move downwards and press against the hard plastic component, driving the steel wire to rotate and evenly transmitting pressure to both ends of the keycap. In the above process, on the one hand, the dummy axis presses against the hard plastic component to indirectly press and drive the steel wire to rotate, which produces less noise (wire noise) compared to the dummy axis directly pressing and driving the steel wire to rotate; on the other hand, the hard plastic component is smoother than the soft rubber sleeve, so it provides lighter pressure damping, which can better optimize the user's experience when pressing long keys, and the hard plastic component is more wear-resistant and has a longer service life; furthermore, the gap between the through hole wall and the hard plastic component allows the hard plastic component to make dynamic contact with the dummy axis, allowing the hard plastic component to have slight displacement relative to the dummy axis, avoiding continuous high-pressure contact, thereby reducing wear and extending service life.

[0009] According to some embodiments of the present invention, the rigid plastic part is sleeved on the corresponding end of the steel wire.

[0010] According to some embodiments of the present invention, the rigid plastic part is integrally injection molded onto the corresponding end of the steel wire.

[0011] According to some embodiments of this utility model, the material of the rigid plastic part is at least one of POM plastic, POK plastic, PC plastic and UPE plastic.

[0012] According to some embodiments of the present invention, the steel wire is provided with a first rod segment and two second rod segments respectively provided at both ends of the first rod segment. The first rod segment is rotatably provided on the base, and the two second rod segments are respectively provided through the two through holes. Both second rod segments are provided with the hard plastic parts.

[0013] According to some embodiments of this utility model, the base is provided with a sliding hole, a through hole, and an abutment platform arranged sequentially from front to back. The base is provided with a clamping opening located on one side of the abutment platform. The through hole communicates with the sliding hole. The two dummy shafts are slidably disposed in the two sliding holes respectively. The two ends of the first rod segment abut against the two abutment platforms respectively and are rotatably inserted through the two clamping openings respectively. The two second rod segments are respectively inserted through the two through holes in the two sliding holes in a one-to-one correspondence through the two through holes.

[0014] According to some embodiments of this utility model, the steel wire has a U-shaped structure.

[0015] According to a second aspect of the present invention, a mechanical keyboard includes a keyboard stabilizer as described above.

[0016] The mechanical keyboard according to the present invention has at least the following beneficial effects: the above structure can reduce noise (wire noise) and reduce wear on hard plastic parts.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0031] In the description of this utility model, the use of terms such as first, second, third, fourth, and fifth is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features indicated, or implicitly indicating the order of the technical features indicated.

Therefore, they should not be construed as limitations on this utility model.

[0033] In this utility model, unless otherwise explicitly defined, the terms "setting," "installing," and "connecting" should be interpreted broadly. For example, they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to a fixed connection, a detachable connection, or an integral molding; they can refer to a mechanical connection; they can refer to the internal connection of two components or the interaction between two components.

[0034] Reference Figures 1 to 5 This utility model embodiment provides a keyboard satellite axis, which includes a base 100, a dummy axis 200, and a steel wire 300.

[0035] Two bases 100 are arranged side by side, and two dummy shafts 200 are arranged on the two bases 100 respectively, which can slide up and down. Each dummy shaft 200 has a through hole 210. A steel wire 300 is rotatably arranged on the base 100. The two ends of the steel wire 300 are respectively inserted through the two through holes 210. Both ends of the steel wire 300 are provided with hard plastic parts 400. The top hole wall of the through hole 210 abuts against the corresponding hard plastic part 400, and the bottom hole wall has a gap 500 between it and the corresponding hard plastic part 400. One of the dummy shafts 200 can slide to abut against the corresponding hard plastic part 400, so that the steel wire 300 rotates to drive the other dummy shaft 200 to slide synchronously.

[0036] When the long key of the mechanical keyboard equipped with the keyboard stabilizer of this application is pressed, the keycap sinks under the force, causing the dummy switch 200 to move downward and press against the hard plastic part 400, driving the steel wire 300 to rotate and evenly transmit the pressure to both ends of the keycap. In the above process, on the one hand, the dummy shaft 200 indirectly drives the steel wire 300 to rotate by pressing against the hard plastic part 400. Compared with the method of the dummy shaft 200 directly driving the steel wire 300 to rotate, the noise (steel wire sound) generated is less. On the other hand, the hard plastic part 400 is smoother than the soft rubber sleeve, so it provides a lighter pressure damping feel, which can optimize the user's experience when pressing long keys. Moreover, the hard plastic part 400 is more wear-resistant and has a longer service life. Furthermore, the gap 500 between the bottom hole wall of the through hole 210 and the hard plastic part 400 allows the hard plastic part 400 to make dynamic contact with the dummy shaft 200, allowing the hard plastic part 400 to have slight displacement relative to the dummy shaft 200, avoiding continuous high pressure contact, thereby reducing wear and extending service life.

[0037] In this embodiment, refer to Figure 1 The top of the dummy switch 200 is provided with a cross-shaped protrusion 220 for interference fit with the keycap.

[0038] In this embodiment, the rigid plastic part 400 is integrally injection molded around the corresponding end of the steel wire 300, so as to greatly reduce or avoid the occurrence of the rigid plastic part 400 falling off the steel wire 300.

[0039] In some embodiments, the rigid plastic part 400 is interference-fitted onto the corresponding end of the steel wire 300.

[0040] In this embodiment, the rigid plastic part 400 is made of PC plastic.

[0041] In some embodiments, the material of the hard plastic part 400 may also be POM plastic, POK plastic, UPE plastic, or other plastics with self-lubricating properties and superior wear resistance.

[0042] In this embodiment, refer to Figures 1 to 4 The steel wire 300 has a U-shaped structure. The steel wire 300 has a first rod section 310 and two second rod sections 320 respectively located at both ends of the first rod section 310. The first rod section 310 and the second rod section 320 are arranged perpendicularly. The first rod section 310 is rotatably mounted on the base 100. The two second rod sections 320 are respectively inserted through two through holes 210. Both second rod sections 320 are provided with the aforementioned hard plastic parts 400.

[0043] The first segment 310 is rotatably mounted on the base 100, and the dummy shaft 200 is slidably mounted on the corresponding base 100. For details, refer to... Figure 1 , Figure 2 as well as Figure 5 The base 100 is provided with a sliding hole 110, a through hole 120 and an abutment platform 130 arranged sequentially from front to back. The base 100 is provided with a clamping opening 140 located on one side of the abutment platform 130. The through hole 120 is connected to the sliding hole 110. Two dummy shafts 200 are slidably disposed in the two sliding holes 110 respectively. The two ends of the first rod segment 310 abut against the two abutment platforms 130 respectively and are rotatably inserted through the two clamping openings 140 respectively. Two second rod segments 320 are respectively inserted through the two through holes 210 in the two sliding holes 110 one-to-one through the two through holes 120.

[0044] It is understood that the end of the first rod segment 310 can be inserted into the corresponding clamp 140 from top to bottom. During the insertion process, the clamp 140 deforms and recovers. The recovered clamp 140 can restrict the first rod segment 310 from disengaging upward. In other words, the clamp 140 can restrict the steel wire 300 to only rotate during the pressing process.

[0045] This invention also proposes a mechanical keyboard including the aforementioned keyboard stabilizers. This structure reduces noise (wire noise) and wear on the hard plastic parts 400.

[0046] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
