Description

Technical Field

[0001] The invention relates to the technical field of keyboard switches, and in particular to a pluggable ultra-thin mechanical keyboard switch. Background Art

[0002] A mechanical keyboard is a more complex keyboard than a membrane keyboard. Mechanical switches are used under the keycaps. The cost of a mechanical keyboard is relatively higher than that of a membrane keyboard. It has the characteristics of better feel, crisp sound, and long mechanical life. However, mechanical switches have poor performance in terms of waterproofing and dustproofing, so failures are inevitable.

[0003] The mechanical switches of existing mechanical keyboards are directly soldered on the PCB board, which has obvious defects: once the mechanical switch is defective or damaged, it is difficult to replace the mechanical switch and the maintenance cost is high. End users generally cannot replace it by themselves. Even if they can replace it, it wastes a lot of time and there are hidden dangers of soldering. In addition, this existing technology also prevents end users from choosing different types of mechanical switches for different keys of the keyboard according to their own preferences.

[0004] In addition, the conduction structure of the existing mechanical switch needs to be fixed on a structure such as a housing or a conductor core. The structure is relatively delicate and requires high precision for fixation. The technology is difficult and consumes a lot of manpower and material resources, which is not suitable for current rapid production needs.

[0005] As electronic products tend to be thinner and thinner, existing pluggable and replaceable keyboard switches are increasingly unable to keep up with the trend of thinning. Summary of the invention

[0006] In view of the above-mentioned deficiencies, the object of the present invention is to provide a pluggable ultra-thin mechanical keyboard switch, which has good contact stability, convenient and quick installation of the internal structure, can be freely plugged in and out, is easy to replace, has accurate conduction and disconnection actions, good elastic recovery force, and has a relatively low overall height, good balance, and is lighter and thinner, so as to meet the usage needs of different people.

[0015] As a further improvement of the present invention, a conductive contact portion bent downward is formed on the first elastic arm.

DETAILED DESCRIPTION

[0028] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0031] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] Please refer to Figures 1 to 4 The embodiment of the present invention provides a pluggable ultra-thin mechanical keyboard switch, comprising a base 1, a balance frame assembly 2 rotatably arranged on the base 1, a conducting member 3, and a driving protrusion 21 arranged on the balance frame assembly 2. The driving protrusion 21 drives the conducting member 3 to move up and down with the balance frame assembly 2 to realize the conduction and disconnection of the keyboard switch. The conducting member 3 is a conductive elastic body, and a fixing part 31 is arranged in the middle of the conductive elastic body; a first elastic arm 32 and a second elastic arm 33 are extended to both sides from the fixing part 31 respectively, and a conducting driving part 34 is arranged at the end of the first elastic arm 32, and a conducting fixing part 35 is arranged at the second elastic arm 33; the conducting driving part 34 extends to the top of the conducting driving protrusion 21 to realize the linkage with the balance frame assembly 2. The conducting fixing part 35 is fixedly connected and electrically connected with the PCB board 5.

[0033] When the user presses the balance frame assembly 2, the balance frame assembly 2 is forced to move downward, and the conduction driving part 34 pulled up by the driving protrusion 21 in the balance frame assembly 2 rotates downward with the fixing part 31 as the center under the elastic restoring force of the conduction member 3 itself, so that the first elastic arm 32 is electrically connected and conducted with the PCB board 5, and the conduction fixing part 3531 is fixed and electrically connected with the PCB board 5. When both ends are conductive, a complete loop is formed with the PCB board 5, thereby realizing the input of a signal. When the user releases the balance frame assembly 2, the balance frame assembly 2 moves upward under the action of its own elastic restoring force, and the driving protrusion 21 set on the balance frame assembly 2 moves upward along with the balance frame assembly 2, thereby pulling up the conduction fixing part 3531 pressed on the driving protrusion 21, so that the first elastic arm 32 connected to the conduction fixing part 3531 leaves the PCB board 5, thereby realizing the disconnection of the signal. The whole operation has good connectivity, accurate conduction and disconnection, long service life of the torsion spring, and no separate mold is needed, which saves costs and further improves the practicality of the keyboard switch. The structure of the conducting member 3 and the PCB board 5 in point contact makes it unnecessary for the keyboard switch to set the dynamic and static pins to extend into the PCB board 5 for conduction like the conventional keyboard switch, which is further convenient for plugging and unplugging, easy to replace, and meets the use needs of different people.

[0034] Regarding the specific structural setting of the balance frame assembly 2, as shown in FIG. Figure 1 and Figure 3 As shown, the balance frame assembly 2 includes a balance frame A22 rotatably connected to the base 1, a balance frame B23 rotatably connected to the base 1 and the balance frame A22, and a tension spring 24 connected between the balance frame A22 and the balance frame B23. The driving protrusion 21 is arranged on the inner side of the balance frame B23. The balance frame assembly 2 provides balance and stability for the pressing of the keyboard switch, and the tension spring 24 provides elastic restoring force for pressing and resetting. The balance frame assembly 2, the conductive member 3, the fixing plate 4, and the fixing seat 6 are matched, and the linkage action of the balance frame assembly 2 combines the pressing balance function with the pressing conduction function, thereby reducing the overall height, improving the balance, and having good contact stability, which meets the use needs of different people. In specific use, a key cap is installed on the balance frame A22 and the balance frame B23. The specific structure of the balance frame A22 and the balance frame B23, as well as the installation method of the keycaps are not the innovation points of the present invention. As for the specific structure, the patent number is 202121092814.4, and the patent name is "A photoelectric key switch with increased pressing feel", which will not be repeated here.

[0035] For the specific pluggable mode of the keyboard switch, such as Figures 1 to 3As shown, the keyboard switch also includes a fixing plate 4 arranged in parallel with the PCB board 5, and a snap-fit ​​block 11 respectively arranged on both sides of the base 1, and a buckle 41 corresponding to the buckle block 11 and extending upward is respectively arranged on both sides of the fixing plate 4, and the buckle block 11 and the buckle 41 are snapped to fix the base 1 on the fixing plate 4. When it is necessary to disassemble, it is only necessary to use a sharp-headed object to open the buckle 41, so that the buckle block 11 is separated from the buckle 41, and the keyboard switch can be pulled out to achieve replacement and other operations. The mutual cooperation between the buckle block 11 and the buckle 41 allows the keyboard switch to be freely plugged and unplugged on the PCB board 5, which is easy to replace, and the plug-in installation method is convenient and quick, which improves the user experience and can effectively meet the use needs of different people.

[0036] Regarding the position setting of the fixing plate 4, the fixing plate 4 can be set below the PCB board 5, and the base 1 and the fixing plate 4 fix the PCB board 5, so that other components on the base 1 are electrically connected to the PCB board 5. The fixing plate 4 can also be set above the PCB board 5, the fixing plate 4 is fixed on the PCB board 5, and the base 1 is inserted into the fixing plate 4, so that other components of the pluggable ultra-thin mechanical keyboard switch on the base 1 are electrically connected to the PCB board 5. The two methods can be selected and adjusted according to actual conditions, so no specific restrictions are made in this embodiment.

[0037] For the specific structure of the connection between the PCB board 5 and the conductive member 3, as shown in FIG. Figure 3 As shown, the PCB board 5 is provided with an electrical connection static contact 51 electrically connected to the conduction fixing part 35, and an electrical connection moving contact 52 electrically connected to the conduction driving part 34. The conduction fixing part 35 is fixedly pressed against the electrical connection static contact 51, so as to realize the conduction of one end of the conduction member 3. When the conduction contact part 36 is pressed by the user, the first elastic arm 32 is driven to move downward by its own elastic restoring force, so that the first elastic arm 32 contacts the electrical connection moving contact 52 to realize electrical connection conduction. When both ends are conductive, a complete circuit is formed between the conduction member 3 and the PCB board 5, and a signal input is completed.

[0038] When the fixing plate 4 is arranged below the PCB board 5, the fixing plate 4 and the base 1 are fastened together in a manner such as: Figure 3 As shown, the PCB board 5 is provided with buckle holes 53 corresponding to the buckles 41. When the base 1 needs to be installed on the fixing plate 4, the buckle 41 only needs to be passed through the buckle holes 53, and then the buckle block 11 on the base 1 is buckled into the buckle 41 to complete the installation of the base 1. The whole process is simple and convenient, easy to replace, effectively improving the user experience and meeting the usage needs of different people.

[0039] In order to facilitate the buckle block 11 to buckle into the buckle 41, Figures 1 to 3 As shown, the outermost end of the snap-fit ​​block 11 is provided with a guiding inclined surface 111, and the guiding inclined surface 111 is a guiding inclined surface 111 that is inclined from the outside to the inside and downward. When the user or the manufacturer needs to install the fixing plate 4 on the base 1, the guiding inclined surface 111 first contacts the buckle 41. Under the guiding action of the guiding inclined surface 111, the snap-fit ​​block 11 moves toward the inner side of the buckle 41, so that it is easier to enter the buckle 41 from the inner side of the buckle 41 to complete the installation of the keyboard switch, which is beneficial to the coordination between the various components, improves the speed and accuracy of the base 1 being installed on the fixing plate 4, and further improves the efficiency of the installation.

[0040] Regarding the specific method of installing the conductive member 3 in the keyboard switch, Figures 1 to 3 As shown, the keyboard switch further comprises a fixing seat 6 disposed on the fixing plate 4, the conducting member 3 is installed in the fixing seat 6, and moves in the fixing seat 6 to realize the conduction and disconnection of the key switch.

[0041] Regarding the specific structural arrangement of the conductive member 3, as shown in FIG. Figure 1 and Figure 3 As shown, the conductive elastic body is a torsion spring, which includes a fixing portion 31 mounted on the fixing seat 6, a first elastic arm 32 extending from the fixing portion 31 toward one end of the driving protrusion 21, a conductive driving portion 34 integrally formed at the outermost end of the first elastic arm 32 and bent 90 degrees to extend outward, a second elastic arm 33 extending from the fixing portion 31 toward one end away from the driving protrusion 21, and a conductive fixing portion 35 integrally formed at the outermost side of the second elastic arm 33 and bent 90 degrees to extend inward; the conductive fixing portion 35 presses against the electrical connection static contact 51 of the PCB board 5 to achieve electrical connection. By setting the conductive member 3 as a torsion spring and the overall integrally formed structure, the conductive member 3 is not easy to break, which increases its service life, and does not need to be molded separately, saving costs, and further improving the practicality of the conductive member 3. By providing a conductive driving portion 34 that is bent 90 degrees and extends outward at the outermost end of the first elastic arm 32, the balance frame assembly 2 can better pull up the conductive driving portion 34. By providing a conductive fixing portion 3531 that is bent 90 degrees and extends inward at the outermost end of the second elastic arm 33, the contact surface is large, so that the conductive member 3 can be better fixedly electrically connected with the PCB board 5.

[0042] Regarding the specific structural setting of the first elastic arm 32 being electrically connected to the PCB board 5, as shown in FIG. Figure 2 and Figure 3As shown, a conductive contact portion 36 is formed on the first elastic arm 32 and is bent downward. When the balance frame assembly 2 is forced to move downward, the conductive member 3 takes the fixing portion 31 as the center, and the first elastic arm 32 rotates downward, so that the conductive contact portion 36 on the first elastic arm 32 is electrically connected and conducted with the electrically connected moving contact 52 in the PCB board 5, completing a signal input, and the conduction and disconnection actions are accurate, thereby improving the accuracy and installation efficiency of the keyboard switch.

[0043] The specific method of installing the conductive member 3 on the fixing seat 6 is as follows: Figures 2 to 4 As shown, the fixing seat 6 is provided with a mounting portion 61 for mounting the conductive member 3, and the mounting portion 61 includes a first transverse mounting groove 62 for the conductive driving portion 34, a first longitudinal mounting groove 63 connected to one side of the first transverse mounting groove 62 and for the first elastic arm 32 to be placed in, a fixing portion 31 mounting groove connected to the tail end of the first longitudinal mounting groove 63 and for the fixing portion 31 to be placed in, a second longitudinal mounting groove 65 connected to the other end of the fixing portion 31 mounting groove and for the second elastic arm 33 to be placed in, and a second transverse mounting groove 66 connected to the tail end of the second longitudinal mounting groove 65 and for the conductive fixing portion 35 to be placed in. The conductive fixing portion 35 is pressed against the PCB board 5 through the lower end of the second transverse mounting groove 66. The conductive member 3 is stably mounted on the fixing seat 6 through the one-to-one corresponding mounting groove arrangement, and has sufficient space to move up and down, so as to realize different operations of conduction and disconnection, and accurately limit the moving stroke of each part of the conductive member 3, effectively preventing the conductive member 3 from shifting during the activity and causing the problem of malfunction. The conduction and disconnection actions are accurate, thereby improving the input efficiency of the keyboard switch.

[0044] In order to prevent the conductive member 3 from being separated from the upper part of the fixing seat 6 during the pulling process, as shown in FIG. Figures 1 to 3 As shown, the keyboard switch also includes a dust cover 7 covering the mounting portion 61, and the upper portion of the conductive member 3 is blocked by the dust cover 7, so that the conductive member 3 is better restricted by the mounting portion 61, thereby improving the accuracy of the movement and effectively preventing the conductive member 3 from detaching from the upper portion of the fixing seat 6 when being pulled.

[0045] It should be noted that the pluggable ultra-thin mechanical keyboard switch disclosed in the present invention is an improvement on a specific structure, and the specific control method is not the innovation of the present invention. The key caps, PCB boards and other components involved in the present invention can be general standard parts or components known to those skilled in the art, and their structures, principles and control methods are all known to those skilled in the art through technical manuals or conventional experimental methods.

[0046] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, other structures obtained by adopting the same or similar technical features as the above-mentioned embodiments of the present invention are within the protection scope of the present invention.
