Description

Technical Field

[0001] The invention relates to the technical field of key 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.

[0007] The technical solution adopted by the present invention to achieve the above-mentioned purpose is:

[0008] A pluggable ultra-thin mechanical keyboard switch comprises a base, a balance frame assembly rotatably arranged on the base, a conducting member, and a driving rod driven by the balance frame assembly and triggering the conducting member to be turned on and off, characterized in that: it also comprises a fixing plate arranged in parallel with the PCB board, and a buckle block respectively arranged on both sides of the base, the fixing plate is respectively provided with a buckle corresponding to the buckle block and extending upward on both sides, the buckle block and the buckle are engaged with the buckle to fix the base on the fixing plate; the driving rod is provided with a conducting hook; the conducting member is a conductive elastomer, and a fixing part is provided in the middle of the metal elastomer; a first elastic arm and a second elastic arm are respectively extended to both sides from the fixing part, the end of the first elastic arm is provided with a conducting driving part, and the second elastic arm is provided with a conducting fixing part; the conducting driving part extends into the top of the conducting hook to realize linkage with the driving rod.

[0014] As a further improvement of the present invention, a lower pressing linkage block and an upper pressing linkage block are respectively provided at one end of the driving rod, and a pressing protrusion is protruding on the balancing frame assembly and extends between the lower pressing linkage block and the upper pressing linkage block. When the balancing frame assembly is pressed downward, the pressing protrusion acts on the lower pressing linkage block to drive the driving rod to move downward. When the balancing frame assembly is reset, the pressing protrusion acts on the upper pressing linkage block to drive the driving rod to move upward, thereby driving the conductive part to achieve conduction and disconnection.

[0015] As a further improvement of the present invention, the metal elastic body is a torsion spring, which includes a fixing portion installed on the fixing seat, a first elastic arm extending from the fixing portion toward one end of the conductive hook, a conductive driving portion integrally formed at the outermost end of the first elastic arm and bent 90 degrees to extend outward, a second elastic arm extending from the fixing portion toward one end away from the conductive hook, and a conductive fixing portion integrally formed at the outermost side of the second elastic arm and bent 90 degrees to extend inward; the conductive driving portion is hooked on the conductive hook, and the conductive fixing portion is pressed against the electrical connection static contact of the PCB board to achieve electrical connection.

[0016] As a further improvement of the present invention, a conductive contact portion bent downward is formed on the first elastic arm. When the balance frame assembly is pressed downward, the pressing protrusion acts on the driving rod, and the driving rod acts on the conductive driving portion of the torsion spring through the conductive hook, thereby driving the conductive contact portion until it contacts the electrical connection moving contact on the PCB board to achieve electrical connection, thereby completing a signal input.

[0017] As a further improvement of the present invention, the fixing seat is provided with a mounting portion for installing the conductive part at the position at the lower end of the driving rod, and the mounting portion includes a first transverse mounting groove for the conductive driving part and the conductive hook to be placed, a first longitudinal mounting groove connected to one side of the first transverse mounting groove and for the first elastic arm to be placed in a movable manner, a fixing part mounting groove connected to the tail end of the first longitudinal mounting groove and for the fixing part to be placed in, a second longitudinal mounting groove connected to the other end of the fixing part mounting groove and for the second elastic arm to be placed in a movable manner, and a second transverse mounting groove connected to the tail end of the second longitudinal mounting groove and for the conductive fixing part to be placed in.

[0018] As a further improvement of the present invention, the driving rod is provided with an embedding groove located just above the mounting portion.

When disassembling, the mechanical keyboard switch can be pulled out by simply stretching the snaps. The entire operation is convenient and quick, and easy to replace.

[0022] (2) By using the balance frame assembly, the driving rod, the base and the fixed plate, the push-to-balance function and the push-to-conduction function are combined together through the linkage action of the driving rod, thereby reducing the overall height, improving the balance, and improving the contact stability, thus meeting the needs of different people.

[0023] (3) The structure in which the torsion spring is hooked on the conduction hook makes the installation of the torsion spring easier. The torsion spring only needs to be placed on the drive rod and the base to achieve the conduction and disconnection of the mechanical key. No welding or fixing is required.

DETAILED DESCRIPTION

[0032] 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.

[0034] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. 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.

[0035] 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.

[0036] Please refer to Figures 1 to 6 The embodiment of the present invention provides a pluggable ultra-thin mechanical keyboard switch, comprising a base 6, a balance frame assembly 2 rotatably arranged on the base 6, a conducting member 3, and a driving rod 4 driven by the balance frame assembly 2 and triggering the conducting member 3 to be turned on and off, characterized in that it also includes a fixing plate 5 arranged in parallel with the PCB board 8, and a buckle block 61 respectively arranged on both sides of the base 6, and a buckle 51 corresponding to the buckle block 61 and extending upward is respectively arranged on both sides of the fixing plate 5, and the buckle block 61 is clamped with the buckle 51 to fix the base 6 on the fixing plate 5, thereby completing the insertion and installation of the mechanical keyboard switch. When disassembling, the mechanical keyboard switch can be pulled out by simply stretching the buckle 51. The whole operation is convenient and fast, and it can be freely plugged in and out, and is easy to replace, thereby meeting the different needs of different people for mechanical keyboard switches.

[0037] The driving rod 4 is provided with a conducting hook 42; the conducting member 3 is a conductive elastic body, and a fixing part 31 is provided in the middle of the conductive elastic body; a first elastic arm 32 and a second elastic arm 34 are extended to both sides from the fixing part 31, and a conducting driving part 33 is provided at the end of the first elastic arm 32, and a conducting fixing part 35 is provided at the second elastic arm 34; the conducting driving part 33 extends above the conducting hook 42 to realize linkage with the driving rod 4. By setting the conducting member 3 as a conductive elastic body, its conducting fixing part 35 is stably electrically connected with the PCB board 8, and when the user presses the switch of the mechanical keyboard, the driving rod 4 moves downward, and the conducting driving part 33, under the action of its own elastic restoring force, takes the fixing part 31 as the axis, and the conducting driving part 33 rotates downward to the middle of the first elastic arm 32 to be electrically connected with the PCB board 8, completing a signal input. When the user releases the mechanical keyboard switch, the balance frame assembly 2 drives the driving rod 4 to move upward, and the driving rod 4 pulls up the conduction driving part 33, causing the conduction member 3 to undergo elastic deformation, and the first elastic arm 32 connected to the conduction driving part 33 is driven to separate from the PCB board 8, thereby disconnecting the electrical signal. The mechanical keyboard switch has good contact stability, convenient and quick installation of the internal structure, accurate conduction and disconnection actions, and good elastic recovery force, thereby improving the accuracy and installation efficiency of the mechanical keyboard switch.

[0038] The structure in which the conductive drive part 33 is hung on the conductive hook 42 makes the installation of the conductive component 3 easier. The conductive component 3 only needs to be placed on the drive rod 4 and the base 6 to realize the conduction and disconnection of the mechanical key. No welding and fixing are required. The installation technology requirements are low, the installation is convenient and quick, and manpower and material resources are saved. The conduction and disconnection actions are accurate, and the elastic recovery force is good, which improves the practicability of the mechanical keyboard switch.

[0039] By using the balance frame assembly 2, the driving rod 4, the base 6 and the fixed plate 5, the driving rod 4 is rotatably set on the base 1, and the pressing balance function and the pressing conduction function are combined together by the linkage action of the driving rod 4, thereby reducing the overall height, improving the balance, and ensuring the contact stability.

[0040] For the formation position of the conductive hook, Figure 1 , Figure 3 , Figure 4 as well as Figure 6 As shown, the conducting hook 42 is disposed at the lower end of the driving rod 4 facing the outer end, so that the driving rod 4 can act on the conducting member 3 through the conducting hook 42 when being driven by the balance frame to move up and down.

[0041] The specific method of electrically connecting the conductive member 3 and the PCB board 8 is as follows: Figure 3As shown, the PCB board 8 is provided with an electrical connection static contact 81 electrically connected to the conduction fixing part 35, and an electrical connection moving contact 82 electrically connected to the conduction driving part 33. The conduction fixing part 35 is fixedly pressed against the electrical connection static contact 81, so as to realize the conduction of one end of the conduction member 3. When the user presses, the first elastic arm 32 moves downward by its own elastic restoring force, so that the first elastic arm 32 contacts the electrical connection moving contact 82 to realize electrical connection conduction. When both ends are conductive, a complete circuit is formed between the conduction member 3 and the PCB board 8, and a signal input is completed.

[0042] Regarding the position setting of the fixing plate 5, the fixing plate 5 can be set below the PCB board 8, and the base 6 and the fixing plate 5 fix the PCB board 8, so that the conductive member 3 is electrically connected to the PCB board 8. The fixing plate 5 can also be set above the PCB board 8, the fixing plate 5 is fixed on the PCB board 8, and the base 6 is inserted into the fixing plate 5, so that the conductive member 3 on the base 6 is electrically connected to the PCB board 8. Both methods can be selected and adjusted according to actual conditions, so no specific restrictions are made in this embodiment.

[0043] When the fixing plate 5 is arranged below the PCB board 8, the fixing plate 5 and the base 6 are fastened together in a manner such as: Figure 3 and Figure 6 As shown, the PCB board 8 is provided with buckle clearance holes 83 corresponding to the buckles 51. When the base 6 needs to be installed on the fixing plate 5, the buckle 51 only needs to be passed through the buckle clearance holes 83, and then the buckle block 61 on the base 6 is buckled into the buckle 51 to complete the installation of the base 6. The whole process is simple and convenient, easy to replace, effectively improving the user experience and meeting the usage needs of different people.

[0044] In order to facilitate the buckle block 61 to buckle into the buckle 51, Figure 3 As shown, the outermost end of the snap-fit ​​block 61 is provided with a guiding inclined surface 611, and the guiding inclined surface 611 is a guiding inclined surface 611 inclined from the outside to the inside and downward. When the user or the manufacturer needs to install the fixing plate 5 on the base 6, the guiding inclined surface 611 first contacts the buckle 51. Under the guiding action of the guiding inclined surface 611, the snap-fit ​​block 61 moves toward the inner side of the buckle 51, so that it is easier to enter the buckle 51 from the inner side of the buckle 51 to complete the installation of the mechanical keyboard switch, which is beneficial to the coordination between the various components, improves the speed and accuracy of installing the base 6 on the fixing plate 5, and further improves the efficiency of installation.

[0045] Regarding the specific structural setting of the conductive hook 42, as shown in FIG. Figure 3 and Figure 4As shown, the conduction drive unit 33 is hung on the conduction hook 42, and the "∟"-shaped structural setting makes the conduction component 3 more stable when hooked, and is convenient for the manufacturer to install the conduction component 3 from the side to the conduction hook 42, thereby reducing technical difficulty, facilitating and quickly installing, saving manpower and material resources, and ensuring accurate conduction and disconnection actions, thereby improving the accuracy and installation efficiency of the mechanical keyboard switch.

[0046] Regarding the specific structural setting of the driving rod 4, Figure 3 and Figure 4 As shown, one end of the driving rod 4 is respectively provided with a lower pressing linkage block 41 and an upper pressing linkage block 44, and a pressing protrusion 221 extending between the lower pressing linkage block 41 and the upper pressing linkage block 41 is convexly provided on the balance frame assembly 2. When the balance frame assembly 2 is pressed downward, the pressing protrusion 221 acts on the lower pressing linkage block 41 to drive the driving rod 4 to move downward. When the balance frame assembly 2 is reset, the pressing protrusion 221 acts on the upper pressing linkage block 44 to drive the driving rod 4 to move upward, thereby driving the conducting member 3 to achieve conduction and disconnection. Its structure is tightly matched, which is conducive to the coordination between various components, thereby achieving the purpose of accurate conduction and disconnection, and improving the accuracy and installation efficiency of the mechanical keyboard switch.

[0047] For the specific structural setting of the conductive member, such as Figure 3 and Figure 6 As shown, the conductive elastic body is a torsion spring, which includes a fixing portion 31 mounted on the fixing seat 1, a first elastic arm 32 extending from the fixing portion 31 toward one end of the conductive hook 42, a conductive driving portion 33 integrally formed at the outermost end of the first elastic arm 32 and bent 90 degrees to extend outward, a second elastic arm 34 extending from the fixing portion 31 toward one end away from the conductive hook 42, and a conductive fixing portion 35 integrally formed at the outermost side of the second elastic arm 34 and bent 90 degrees to extend inward; the conductive driving portion 33 is hooked on the conductive hook 42, and the conductive fixing portion 35 is pressed against the electrical connection static contact 81 of the PCB board 8 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 33 bent 90 degrees and extending outward at the outermost end of the first elastic arm 32, the balance frame assembly 2 can better pull up the conductive driving portion 33. By providing a conductive fixing portion 35 bent 90 degrees and extending inward at the outermost end of the second elastic arm 34, the contact surface is large, so that the conductive member 3 can be better fixedly electrically connected with the PCB board 8.

[0048] The specific structural setting of the first elastic arm 32 being electrically connected to the PCB board 8 is as follows: Figure 3and Figure 6 As 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 82 in the PCB board 8, completing a signal input, and the conduction and disconnection actions are accurate, thereby improving the accuracy and installation efficiency of the keyboard switch.

[0049] The specific method of installing the conductive member 3 on the fixing seat 1 is as follows: Figure 5 As shown, the fixing seat 1 is provided with a mounting portion 11 for mounting the conductive member 3, and the mounting portion 11 includes a first transverse mounting groove 111 for the conductive driving portion 33, a first longitudinal mounting groove 112 connected to one side of the first transverse mounting groove 111 and for the first elastic arm 32 to be placed in, a fixing portion mounting groove 113 connected to the tail end of the first longitudinal mounting groove 112 and for the fixing portion 31 to be placed in, a second longitudinal mounting groove 114 connected to the other end of the fixing portion mounting groove 113 and for the second elastic arm 34 to be placed in, and a second transverse mounting groove 115 connected to the tail end of the second longitudinal mounting groove 114 and for the conductive fixing portion 35 to be placed in. The conductive fixing portion 35 is pressed against the PCB board 8 through the lower end of the second transverse mounting groove 115. The conductive member 3 is stably mounted on the fixing seat 1 through one-to-one corresponding mounting grooves, and has sufficient space to move up and down to realize different operations of conduction and disconnection, and accurately limits 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.

[0050] Regarding the specific relationship between the driving rod 4 and the fixing base 1 when the driving rod 4 moves, as shown in FIG. Figure 1 , Figure 3 as well as Figure 4 As shown, the driving rod 4 is provided with an embedding groove 43 located just above the mounting portion 11. When the driving rod 4 moves downward, the mounting portion 11 is embedded in the embedding groove 43, so that the driving rod 4 can move on the fixing seat 1, thereby realizing the elastic reset of the conductive driving portion 33 and the conductive hook 42, so that the switch of the mechanical keyboard is turned on. When the driving rod 4 moves upward, the mounting portion 11 leaves the embedding groove 43, and the conductive hook 42 of the driving rod 4 pulls up the conductive driving portion 33 and the first torsion arm 32, thereby realizing the disconnection of the switch of the mechanical keyboard. The whole operation is smooth, and the mounting portion 11 corresponds to the structure that moves on the embedding groove 43, so that the movable stroke of the embedding groove 43 is limited, thereby improving the activity accuracy of the driving rod 4 and the input efficiency of the mechanical keyboard switch.

[0051] In order to prevent the conductive member 3 from being separated from the upper part of the fixing seat 1 during the pulling process, as shown in FIG. Figure 1 as well as Figure 3 As shown, the mechanical keyboard switch also includes a dust cover 7 covering the embedding groove 43, and the upper part 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 11, thereby improving the accuracy of the movement and effectively preventing the conductive member 3 from detaching from the upper part of the base 1 when being pulled.

[0052] In this embodiment, if Figure 1 as well as Figure 3 , the balance frame assembly 2 includes a balance frame A21 rotatably connected to the base 1, a balance frame B22 rotatably connected to the base 1 and the balance frame A21, and a tension spring 23 connected between the balance frame A21 and the balance frame B22, and the pressing protrusion 221 is arranged on the balance frame B. The balance frame assembly 2 provides balance and stability for the pressing of the mechanical keyboard switch, and the tension spring 23 provides elastic restoring force for pressing and resetting. In specific use, a keycap is installed on the balance frame A21 and the balance frame B22. The specific structure of the balance frame A21 and the balance frame B22, and the installation method with the keycap are not the innovation points of the present invention. For the specific structure, the patent number is 202121092814.4, and the patent name is "A photoelectric key switch with increased pressing feel". Invention patent, no further description is given here.

[0053] The driving rod 4 touches and presses down to make the conductive contact part 36 just conduct the PCB board 8, or the driving rod 4 applies force to further press the conductive driving part 33 downward to conduct the PCB board 8, which are all within the protection scope of the present invention.

[0054] 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.

[0055] 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.
