Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical keyboards, and in particular relates to a mechanical keyboard satellite axis with an elastic structure. Background Art

[0002] Mechanical keyboards have multiple keys that can input commands and data to computer devices. At present, with the development of related industries such as games, more and more users will choose a mechanical keyboard with excellent feel and clean tapping sound. There are large keys such as space, shift, and Enter on the keyboard. Because the pressing area of ​​the keycap is large, it is easier to tilt the key to one side when pressing, and it cannot be pressed smoothly, so a key auxiliary structure is usually installed on the mechanical keyboard. The auxiliary structure mainly enables the above-mentioned large key to achieve the function of synchronously pressing the entire key smoothly when the user presses one side. There are usually two forms of auxiliary structures on the market. One is called a balance bar and the other is a satellite axis. These two types of structures only differ in the installation form. The principle is to use steel wire to connect the plastic movable parts on both sides (also called false axis, small bean) to achieve the force balancing effect. At present, the satellite axis on the market has a large gap size inside the small bean because the steel wire will swing up and down in it. When the key is pressed up and down, a collision noise will be generated, which greatly reduces the user experience.

[0003] In view of this, the present utility model is proposed. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a mechanical keyboard satellite axis with an elastic structure. To solve the above technical problem, the basic concept of the technical solution adopted by the utility model is:

[0005] A mechanical keyboard satellite axis with an elastic structure includes a balancing steel wire and a key structure assembled on both sides thereof, the key structure including a key core and a base, the key core is provided with a through hole, a pressing plate is provided in the key core near the upper part of the through hole, a thin-walled structure is provided below the pressing plate, a thick-walled structure is provided below the thin-walled structure, an arc-shaped placement groove is provided at one end of the outer side of the base, a cross-shaped boss is integrally provided on the upper part of the key core, an accommodating hole is opened on the base, and the key core is installed in the accommodating hole.

[0006] As a further solution of the utility model: the balance steel wire is a U-shaped structure, the two ends of the balance steel wire are inserted into the through hole of the key core, the main body of the balance steel wire is installed in the arc-shaped placement groove of the base near the two ends, and the bases at both ends are linked through the balance steel wire.

[0007] As a further solution of the utility model: a limiting foot is arranged at the lower part of the key core, and a limiting matching platform is arranged at the upper part of the accommodating hole and at a position corresponding to the limiting foot. The limiting matching platform is used to cooperate with the limiting foot for limiting. The accommodating hole enables the key core to provide a constraint on the movement direction when it is pressed, and constrains the key core from falling off the base when it is popped up.

[0008] As a further solution of the utility model: a transition slope is provided on the pressing plate near the insertion end of the balancing steel wire. After the balancing steel wire is inserted into the through hole, it is precisely matched with the pressing plate and the thin-wall structure without any gap, and no steel wire collision noise is generated during the button pressing process.

[0009] After adopting the above technical scheme, the utility model has the following beneficial effects compared with the prior art.

[0010] The satellite axis of the mechanical keyboard of the utility model is installed on the keyboard circuit board by screws and has excellent stability. The buckle above the arc placement groove prevents the balance wire from falling off when it moves, thus ensuring the integrity of the structure. The thin-wall elastic structure in the key core makes the steel wire and the key core fit together without a gap, and no steel wire collision noise is generated during the key pressing process. In addition, since there is no gap, the response speed of the synchronous movement of the key cores at both ends is improved, making the key pressing process smoother and more sensitive.

[0011] The cross-shaped boss on the satellite shaft key core of the utility model can be used with keycaps of most brands on the market and has extremely high interchangeability.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0023] like Figures 1 to 6 As shown, a mechanical keyboard satellite axis with an elastic structure includes a balancing steel wire 1 and a key structure assembled on both sides thereof, the key structure including a key core 3 and a base 2, a through hole 5 is arranged in the key core 3, a pressing plate 10 is arranged near the upper part of the through hole 5 in the key core 3, a thin-walled structure 11 is arranged below the pressing plate 10, a thick-walled structure 12 is arranged below the thin-walled structure 11, an arc-shaped placement groove 4 is arranged at one end of the outer side of the base 2, a cross-shaped boss 7 is integrally arranged on the upper part of the key core 3, an accommodating hole 6 is opened on the base 2, and the key core 3 is installed in the accommodating hole 6.

[0024] Among them, the balancing steel wire 1 is a U-shaped structure, and the two ends of the balancing steel wire 1 are inserted into the through hole 5 of the key core 3. The main body of the balancing steel wire 1 is installed in the arc placement groove 4 of the base 2 near the two ends, and the bases 2 at both ends are linked through the balancing steel wire 1.

[0025] A limiting foot 8 is set at the lower part of the key core 3, and a limiting matching platform 9 is set at the upper part of the accommodating hole 6 and at a position corresponding to the limiting foot 8. The limiting matching platform 9 is used to cooperate with the limiting foot 8 for limiting. The accommodating hole 6 enables the key core 3 to provide a constraint on the movement direction when it is pressed, and constrains the key core 3 from falling off the base 2 with the movement when it is popped up.

[0026] The pressing piece 10 is provided with a transition slope near the insertion end of the balancing steel wire 1. After the balancing steel wire 1 is inserted into the through hole 5, it is precisely matched with the pressing piece 10 and the thin-walled structure 11 without any gap, and no steel wire collision noise is generated during the key pressing process.

[0027] The working principle of the utility model is as follows: the balancing steel wire 1 is made of stainless steel, which has good anti-corrosion performance and good durability; the base 2 and the key core 3 are made of plastic, with a short manufacturing cycle, excellent material mechanical properties, small friction when pressed, and smooth feel; the balancing steel wire 1 is a U-shaped structure, and the through holes 5 of the key core 3 are inserted at both ends during assembly. When the key core 3 is pressed, the balancing steel wire 1 immediately rotates with the arc-shaped placement groove 4 of the base 2 as the center, thereby driving the key core 3 on the other side to move downward;

[0028] The base 2 of the key structure is installed on the mechanical keyboard circuit board by means of buckles and screws. They are usually installed in pairs. The key core 3 is placed in the receiving hole 6 of the base 2. The receiving hole 6 allows the key core 3 to provide a constraint on the movement direction when pressed, and constrains the key core 3 from falling off the base 2 with the movement when it pops up. The base 2 is also provided with an arc-shaped placement groove 4 that cooperates with the balance wire 1. The placement groove cooperates with the balance wire 1 in the form of a clip connection, which not only provides the function of stabilizing the movement of the wire, but also ensures that the wire will not fall off, thereby causing the structure to fail.

[0029] A through hole 5 is arranged inside the key core 3 of the key structure, and a thin-walled structure 11 is arranged inside the through hole 5. When the balance steel wire 1 passes through the hole, it will contact the thin-walled structure 11. The gap here is smaller than the diameter of the balance steel wire 1. Since the structure has a certain elasticity, the steel wire can be tightly contacted with the through hole 5 both above and below to achieve a gap-free fit, thereby achieving the effect of no collision noise, and a thick wall is arranged below the thin-walled structure 11. The thick wall serves to protect the thin-walled structure 11 from always moving within the elastic limit, and a cross-shaped boss 7 of universal size is arranged on the upper part of the key core 3, and the cross boss is connected to the keycap to achieve installation.

[0030] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Although the utility model has been disclosed as a preferred embodiment as above, it is not used to limit the utility model. Any technician familiar with this patent can make some changes or modify the technical content suggested above into an equivalent embodiment with equivalent changes without departing from the scope of the technical solution of the utility model. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the content of the technical solution of the utility model still falls within the scope of the solution of the utility model.
