Description

An integrated inductive keypad module Technical Field

[0001] This utility model relates to the field of keyboard technology, and in particular to an integrated inductive axis keyboard module. Background Technology

[0002] The keyboard is the most commonly used and primary input device. Through the keyboard, English letters, Chinese characters, numbers, punctuation marks, etc., can be input into the computer, thereby issuing commands and inputting data.

[0003] Most keyboards on the market typically have a single key switch mounted on a separate bracket, with multiple switches requiring multiple brackets, resulting in a complex design, low production efficiency, and unsuitability for high-speed production. Furthermore, conventional keyboards generally use mechanical key switches. When these mechanical key switches are pressed, the moving and stationary contacts make contact, causing a short circuit and sending a signal to perform the corresponding operation. Over time, the contact surfaces of the moving and stationary contacts wear down, leading to frequent accidental key presses or loss of contact, which is detrimental to daily use. Utility Model Content

[0004] To address the aforementioned shortcomings, the purpose of this utility model is to provide an integrated inductive switch keyboard module, which integrates multiple inductive switches onto a single positioning plate, effectively improving assembly efficiency, saving production costs, meeting current production needs, and ensuring that the switch body is an inductive switch structure, which not only guarantees the precise linear conduction of this keyboard module, but also effectively guarantees the service life of this keyboard module, benefiting people's daily use.

[0005] The technical solution adopted by this utility model to achieve the above objectives is as follows:

[0006] An integrated inductive keyboard module includes a positioning plate, a plurality of inductive axes sequentially mounted on the positioning plate, and a main circuit board disposed between the inductive axes and the positioning plate. The positioning plate has a plurality of mounting slots that match the inductive axes. On both sides of the mounting slots, there are positioning fixing plates that are bent upward and extend through the main circuit board and engage with the inductive axes. At least one positioning fixing groove is formed on the positioning fixing plate. On both sides of the inductive axes, at least one positioning protrusion is formed that protrudes outward and extends into the positioning fixing groove.

[0007] As a further improvement of this utility model, the uppermost end of the positioning and fixing plate is formed with a guide mounting plate that extends outward and upward at an angle.

[0008] As a further improvement of this utility model, it also includes a light guide assembly disposed on the positioning plate. The light guide assembly includes a light guide plate disposed under the positioning plate, a reflective paper disposed under the light guide plate, and a light-emitting circuit board connected to the light guide plate and the reflective paper.

[0009] As a further improvement of this utility model, a first coil is provided on the main circuit board, which is located directly below the inductor shaft. A main circuit clearance groove is formed on the main circuit board for the positioning and fixing plate to pass through. A main circuit light guide clearance groove is formed on the main circuit board located below the inductor shaft.

[0010] As a further improvement of this utility model, it also includes a coil circuit board located between the inductor shaft and the positioning plate and electrically connected to the main circuit board. A second coil is provided on the coil circuit board, which is located directly below the inductor shaft. A coil circuit clearance groove for the positioning plate to pass through is formed on the coil circuit board, and a coil circuit light guide clearance groove located below the inductor shaft is formed on the coil circuit board.

[0011] As a further improvement of this utility model, it also includes a decorative cover disposed on the positioning plate and allowing the inductor shaft to protrude.

[0012] As a further improvement of this utility model, a keycap is correspondingly installed on the inductor shaft.

[0013] As a further improvement of this utility model, the inductor shaft includes a base fastened to the positioning and fixing plate, a balance frame assembly hinged to the base, a reset elastic element disposed between the balance frame assemblies, a metal part disposed on the balance frame assembly, and an upper cover disposed on the balance frame. The positioning protrusions are disposed on both sides of the base, and the keycap is disposed on the upper cover.

[0014] The beneficial effects of this utility model are as follows:

[0015] This keyboard module is configured to include a positioning plate, several inductor shafts sequentially mounted on the positioning plate, and a main circuit board positioned between the inductor shafts and the positioning plate. The positioning plate has several mounting slots that match the inductor shafts. On both sides of each mounting slot are positioning fixing plates that bend upwards, extend through the main circuit board, and engage with the inductor shafts. Each positioning fixing plate has at least one positioning fixing groove. On both sides of each inductor shaft are at least one positioning protrusion that protrudes outwards and enters the positioning fixing groove. The inductor shaft is inserted into the positioning fixing groove via the positioning protrusion, thereby securing itself between the two sets of positioning fixing plates. The purpose of fixing the inductor shafts to the positioning plate is to form a complete module structure by sequentially installing multiple inductor shafts on a positioning plate. This effectively improves assembly efficiency, reduces the cost and time of producing multiple brackets to install the inductor shafts separately, saves production costs, and effectively meets current production needs. Furthermore, the inductor shaft structure ensures precise linear conduction of the keyboard module and effectively guarantees its service life, which is beneficial for daily use. By placing the main circuit board between the inductor shafts and the positioning plate, the main circuit board is fixed between the two while the inductor shafts are fixed to the positioning plate, thus achieving the fixation of the main circuit board and realizing precise conduction.

[0029] Referring to Figures 1 to 6, this embodiment of the present invention provides an integrated inductor shaft 2 keyboard module, including a positioning plate 1, several inductor shafts 2 sequentially mounted on the positioning plate 1, and a main circuit board 3 disposed between the inductor shafts 2 and the positioning plate 1. The positioning plate 1 has several mounting slots 11 that match the inductor shafts 2. On both sides of the mounting slots 11, there are positioning fixing plates 12 that are bent upward and extend through the main circuit board 3 and are engaged with the inductor shafts 2. At least one positioning fixing groove 121 is formed on the positioning fixing plate 12. On both sides of the inductor shafts 2, at least one positioning protrusion 21 is formed that protrudes outward and extends into the positioning fixing groove 121. The inductor shaft 2 is inserted into the positioning and fixing groove 121 via the positioning protrusion 21, thereby fastening itself between the two sets of positioning and fixing plates 12, thus fixing the inductor shaft 2 onto the positioning plate 1. By sequentially installing multiple inductor shafts 2 onto a positioning plate 1 to form an integral module structure, the assembly efficiency is effectively improved, reducing the cost and time of producing multiple brackets to install the inductor shafts 2, saving production costs, and effectively meeting the needs of today's rapidly developing production. Furthermore, the shaft body is the structure of an inductor shaft 2, and the inductor shaft 2 uses a metal part to approach the coil to achieve signal transmission. The action of the relay does not require contact between the metal parts and the coil, reducing wear, improving the accuracy of conduction, and allowing different strokes to correspond to different operating signals, thereby achieving fine classification and meeting the needs of multi-level signal output. While ensuring the precise linear conduction of this keyboard module, it also effectively guarantees the service life of this keyboard module, which is beneficial to people's daily use. By setting the main circuit board 3 between the inductor shaft 2 and the positioning plate 1, the inductor shaft 2 is fixed to the positioning plate 1, and the main circuit board 3 is clamped between the two, thus achieving the fixation of the main circuit board 3 and realizing precise conduction.

[0030] To facilitate the installation of the inductor shaft 2 on the positioning plate 1, as shown in Figures 4 and 6, a guide mounting plate 122 extending outward and upward is formed at the uppermost end of the positioning fixing plate 12. When the inductor shaft 2 is installed on the positioning plate 1, the positioning protrusion 21 on the inductor shaft 2 first contacts the guide mounting plate 122. Under the inclined guiding action of the guide mounting plate 122, the positioning protrusion 21 moves towards the two sets of positioning fixing plates 12, thereby making the inductor shaft 2 more accurate and easier to install on the positioning plate 1, improving the production efficiency and installation accuracy of this keyboard module.

[0031] Preferably, as shown in Figures 1 and 2, to make the keyboard module more practical, the keyboard module further includes a light guide component 4 disposed on the positioning plate 1. The light guide component 4 includes a light guide plate 41 disposed under the positioning plate 1, a reflective paper 42 disposed under the light guide plate 41, and a light-emitting circuit board 43 connected to the light guide plate 41 and the reflective paper 42. The light-emitting circuit board 43 is connected to an external circuit and emits light. The light passes through the reflective paper 42 and the light guide plate 41 in sequence and is refracted onto the inductor shaft 2 at multiple angles, thereby realizing the backlight function, improving the aesthetics of the keyboard module, making the keyboard module more practical, and meeting the usage needs of different people.

[0032] Preferably, as shown in Figure 2, in order to make the keyboard module more robust, mounting holes for screws to pass through are formed on the four corners of the positioning plate 1, the light guide plate 41, and the reflective paper 42. By passing four sets of screws through the mounting holes at the four corners of the positioning plate 1, the light guide plate 41, and the reflective paper 42, the positioning plate 1, the light guide plate 41, and the reflective paper 42 are fixed, ensuring the normal operation of the keyboard module.

[0033] As shown in Figures 3 and 4, the main circuit board 3 has a first coil 31 located directly below the inductor shaft 2. When the inductor shaft 2 is pressed, its internal metal component approaches the first coil 31, inducing a signal in the conductor within the electromagnetic field range, thereby transmitting a signal outward and realizing input. The main circuit board 3 has a main circuit clearance groove 32 through which the positioning and fixing plate 12 passes. When the positioning and fixing plate 12 extends upward, it passes through the main circuit clearance groove 32 and engages with the positioning protrusion 21. This allows the positioning and fixing plate 12 to be cleared while simultaneously fixing the main circuit board 3 between the positioning plate 1 and the inductor shaft 2, ensuring the normal operation of the keyboard module, effectively improving assembly efficiency, saving production costs, and meeting current production needs. The main circuit board 3 has a main circuit light guide clearance groove 33 located below the inductor shaft 2. By setting the main circuit light guide clearance groove 33 to make way for the light guide component 4, the light refracted from the light guide plate 41 and the reflective paper 42 can pass through the main circuit light guide clearance groove 33, thereby achieving a significant light and shadow effect, improving the aesthetics of the keyboard module, making the keyboard module more practical, and meeting the needs of different users.

[0034] Preferably, the coil and other structures can also be set separately, as shown in Figures 5 and 6. Specifically, this keyboard module also includes a coil circuit board 5 located between the inductor shaft 2 and the positioning plate 1 and electrically connected to the main circuit board 3. By separately setting a coil circuit board 5 between the inductor shaft 2 and the positioning plate 1, the coil circuit board 5 can be disassembled separately for maintenance, or it can be installed as a whole module with the inductor shaft 2 during production, thereby improving production efficiency. A second coil 51 is provided on the coil circuit board 5, located directly below the inductor shaft 2. When the inductor shaft 2 is pressed, the metal part inside it approaches the second coil 51, causing the wires within the electromagnetic field range to be induced, thereby transmitting signals outward to realize input. The coil circuit board 5 has a coil circuit clearance groove 52 through which the positioning and fixing plate 12 passes. When the positioning and fixing plate 12 extends upward, it passes through the coil circuit clearance groove 52 and engages with the positioning protrusion 21. This achieves simultaneous clearance of the positioning and fixing plate 12 and fixation of the coil circuit board 5 between the positioning plate 1 and the inductor shaft 2, ensuring the normal operation of the keyboard module, effectively improving assembly efficiency, saving production costs, and meeting current production needs. The coil circuit board 5 also has a coil circuit light guide clearance groove 53 located below the inductor shaft 2. By setting the coil circuit light guide clearance groove 53 to make way for the light guide component 4, light refracted from the light guide plate 41 and the reflective paper 42 can pass through the coil circuit light guide clearance groove 53, thereby achieving a significant light and shadow effect, improving the aesthetics of the keyboard module, making the keyboard module more practical, and meeting the needs of different users.

[0035] Preferably, as shown in Figures 1 and 2, the keyboard module further includes a decorative cover 6 disposed on the positioning plate 1 and allowing the inductor shaft 2 to protrude. The color, outer frame shape, etc. of the decorative cover 6 can be set according to people's needs. The decorative cover 6 covers the positioning plate 1, thereby limiting and protecting the inductor shaft 2, and can also meet the different people's needs for the appearance of the keyboard, which is beneficial to people's daily use.

[0036] Preferably, as shown in Figures 1 to 6, keycaps 7 are installed on the inductor shaft 2. The keycaps 7 can be pre-installed on the inductor shaft 2 to form an integral module, so that the inductor shaft 2 can be installed as an integral module when it is installed on the positioning plate 1, which further improves production efficiency. Furthermore, the color, pattern, etc. on the keycaps 7 can be set according to people's needs, further satisfying different people's needs for keyboard appearance and facilitating people's daily use.

[0037] Regarding the structural configuration of the inductor shaft 2, the inductor shaft 2 can be a conventional structure available on the market, such as including a base that can be mounted on a positioning plate, a top cover that is fastened to the base, a guide core that moves between the base and the top cover, a reset elastic element disposed between the guide core and the base, a metal part disposed on the guide core, positioning protrusions disposed on both sides of the base, and the keycap disposed on the top cover. When the guide core is pressed, it drives the metal part to move downward and closer to the coil, causing the wires within the electromagnetic field range to be induced, thereby transmitting signals outward and realizing input. There is no need for contact between the metal part and the coil, reducing wear, improving the accuracy of conduction, and allowing different strokes to correspond to different operating signals, thereby achieving fine classification and meeting the usage requirements of multi-level signal output. To meet the demand for thinner and lighter keyboards, as shown in Figures 1 to 6, the inductor shaft 2 can also be configured with a base 22 fastened to the positioning plate 12, a balance frame assembly 23 hinged to the base 22, a reset elastic element 24 disposed between the balance frame assemblies 23, a metal part 25 disposed on the balance frame, and an upper cover 26 disposed on the balance frame. The positioning protrusions 21 are disposed on both sides of the base 22, and the keycaps 7 are disposed on the upper cover 26. When the upper cover 26 is pressed, the balance frame deforms downward, thereby driving the metal part 25 disposed on it to move downward and closer to the coil. The wires within the electromagnetic field range are induced, thereby transmitting signals outward to realize input. There is no need for contact between the metal part 25 and the coil, reducing wear, improving the accuracy of conduction, and allowing different strokes to correspond to different operation signals, thereby achieving fine classification and meeting the needs of multi-level signal output. Furthermore, the structure of the balance frame makes the entire inductor shaft 2 thinner and lighter, meeting the needs of people using different keyboards. The inductor shaft 2 can also be configured in other ways, which can be adjusted and set according to the actual situation. Its operation mode and principle are all conventional technical means in the field, so they will not be described in detail in this embodiment.

[0038] It should be noted that the integrated inductive axis keyboard module disclosed in this utility model is an improvement on the specific structure, but the specific control method is not the innovation of this utility model. The coils, top cover, base, balance frame, reset elastic element, light guide plate, reflective paper, light-emitting circuit board, keycaps, decorative cover, and other components involved in this utility model can be general standard parts or components known to those skilled in the art. Their structure, principle, and control method are all known to those skilled in the art through technical manuals or through conventional experimental methods.

[0039] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, other structures obtained by using the same or similar technical features as the above embodiments of the present utility model are all within the protection scope of the present utility model.
