[0001] This invention relates to the field of keyboard structure technology, and in particular to a keyboard with adjustable pressing elasticity. Background Technology

[0002] Currently, keyboards generally use a pad structure design to improve the soft and bouncy feel when pressing keys. However, existing pad structure keyboard designs do not have adjustable key elasticity settings. Since different users have different needs for the keyboard's key pressure effect, the existing pad structure cannot be adjusted according to the key elasticity effect preferred by different users. Summary of the Invention

[0003] The main objective of this invention is to provide a keyboard with adjustable key press elasticity, which aims to adjust the key press elasticity of the keyboard.

[0004] To achieve the above objectives, the present invention proposes a keyboard with adjustable press elasticity, the keyboard comprising:

[0005] A housing having a receiving cavity with an opening;

[0006] A button module is installed inside the receiving cavity, and the button module includes an interactive side that is exposed from the outside through the opening.

[0007] An elastic element, one end of which is fixed to the housing and the other end of which is fixed to the button module, is used to provide an elastic force for the button module to move away from the opening and away from the housing;

[0008] An adjusting member, one end of which can abut against the elastic member, and the other end of which can abut against the button module or the housing, the adjusting member being used to adjust the elastic force provided by the elastic member to the button module;

[0009] When pressure is applied toward the interactive side, the button module has a force from the opening toward the elastic element that abuts against the housing.

[0010] In some embodiments of the present invention, the elastic element extends at an angle from one end of the button module at one end of the housing;

[0011] One end of the adjusting member can abut against any position between the two ends of the elastic member.

[0012] In some embodiments of the present invention, the elastic member includes a first inclined segment, a second inclined segment, and a first abutting segment, wherein the first inclined segment and the second inclined segment both extend inclinedly from one end of the elastic member toward the keyboard module;

[0013] The first abutting section is located between the first inclined section and the second inclined section, and the first abutting section is used for the adjusting member to abut against.

[0014] In some embodiments of the present invention, the elastic member further includes a third inclined section and a second abutting section, wherein the third inclined section extends obliquely from one end of the elastic member toward the keyboard module;

[0015] The second inclined section is located between the third inclined section and the first inclined section, and the second abutting section is located between the second inclined section and the third inclined section. The second abutting section is used for the adjusting member to abut.

[0016] In some embodiments of the present invention, the keyboard module is provided with a first mounting position for mounting the elastic element, and the housing is provided with a second mounting position for mounting the elastic element;

[0017] The first mounting position and the second mounting position are positioned facing each other.

[0018] In some embodiments of the present invention, the housing is provided with a fixing position for the adjusting member to abut against, and the fixing position is one or more.

[0019] One or more of the fixed positions are spaced apart from one end of the elastic element along the other end of the elastic element.

[0020] In some embodiments of the present invention, the first inclined segment, the second inclined segment, and the third inclined segment are all set at an angle to the horizontal plane, and the angle is 5-25 degrees.

[0021] In some embodiments of the present invention, the elastic member further includes a fixing segment fixed to the housing, the fixing segment extending horizontally from one end of the elastic member away from the side of the first inclined segment away from the second inclined segment;

[0022] A reinforcing rib is provided at the angle between the first inclined section and the fixed section.

[0023] In some embodiments of the present invention, the first abutting section is horizontally arranged, and the second abutting section is a boss-shaped protrusion facing the side of the housing;

[0024] The abutting side of the boss is on the same horizontal plane as the abutting side of the first abutting segment.

[0025] In some embodiments of the present invention, the keyboard further includes a cushioning pad, which is installed between the key module and the housing.

[0026] This invention provides a keyboard user interface by pressing buttons on the interactive side of the button module. The button module is elastically connected to the housing via an elastic element, providing a rebound force when the button is pressed.

[0037] This invention proposes a keyboard 1000 with adjustable press elasticity. The keyboard 1000 includes a housing 100, a key module 200, an elastic element 300, and an adjusting element 400. The key module 200 is assembled with the housing 100 to realize the use of the keyboard 1000. The elasticity of the elastic element 300 achieves the elastic effect when the key module 200 is pressed. The adjusting element 400 can be installed or removed from the elastic element 300 to realize the elastic adjustment of the key module 200 by the elastic element 300. It should be noted that the keyboard 1000 can be a separate key module 200 structure or an integrated key module 200 structure. The layout structure of the keyboard 1000 can be various, and no specific limitation is made here.

[0038] See attached Figure 1-2 The housing 100 has a receiving cavity with an opening, through which related components that mate with the housing 100 can be installed.

[0039] The button module 200 is installed in the receiving cavity. The button module 200 includes an interactive side that is exposed from the outside through the opening. The installation and positioning of the button module 200 is achieved through the housing 100. The user can operate the keyboard 1000 module by pressing the interactive side. When pressure is applied to the interactive side, the button module 200 has a force that abuts against the elastic member 300 from the opening toward the housing 100.

[0040] In this embodiment, the button module 200 includes a button body, a PCBA board, and a positioning plate connected in sequence. The positioning plate is positioned and installed in the receiving cavity. When the button body is pressed, the PCBA board outputs an interactive signal. There are various structures of the button module 200 that can output a press interactive signal, which will not be listed here.

[0041] It should be noted that the interactive side of the key module 200 can protrude outward from the opening or be located inside the opening. The keyboard 1000 can interactively press the key module 200 through the opening. The specific cooperation between the housing 100 and the key module 200 is not further limited here.

[0042] One end of the elastic element 300 is fixed to the housing 100, and the other end is fixed to the button module 200. The elastic element 300 is used to provide elastic force for the button module 200 to move away from the opening and away from the housing 100. When the pressing side of the button module 200 is pressed, the elastic force provided by the elastic element 300 to the button module 200 realizes the provision of the pressing rebound force of the button module 200. The elastic element 300 can be a spring or an elastic metal sheet. The structure of the elastic element 300 can be multiple, which will not be listed here.

[0043] One end of the adjusting member 400 can abut against the elastic member 300, and the other end of the adjusting member 400 can abut against the key module 200 or the housing 100. The adjusting member 400 is used to adjust the elastic force provided by the elastic member 300 to the key module 200. When the adjusting member 400 abuts against the elastic member 300, the rigid connection distance between the elastic member 300 and the key module 200 is changed because the adjusting member 400 abuts against the elastic member 300 from the key module 200 or the housing 100. This further changes the elastic abutting force between the elastic member 300 and the keyboard 1000 module. The elasticity of the key module 200 can be adjusted by adding or removing the adjusting member 400. It should be noted that the adjusting member 400 can have one or more abutting positions. By intervening in the elastic force of the elastic member 300 according to different abutting positions, different elastic effects can be adjusted.

[0044] Based on the aforementioned technical features, the keyboard 1000 allows users to interact with the keyboard 1000 by pressing the interactive side of the key module 200. The key module 200 is elastically connected to the housing 100 via an elastic element 300, ensuring that the key module 200 provides a rebound force when pressed. When adjustment of the pressing force of the key module 200 is required, an adjustment mechanism is installed between the elastic element 300 and the housing 100, or between the elastic element 300 and the key module 200. The adjustment component 400 abuts against the elastic component 300, thereby changing the abutting force of the elastic component 300 and adjusting the pressing elasticity of the key module 200. By assembling and removing the adjustment component 400, users can experience different elasticity effects of the elastic component 300. Users can adjust, install, or remove the adjustment component 400 according to their own needs, so as to achieve different pressing elasticity when using the keyboard 1000, thus improving the adaptability to different user groups.

[0045] Specifically, the elastic element 300 extends obliquely from one end of the housing 100 to one end of the button module 200. When the button module 200 is pressed, the elastic element 300, being obliquely positioned, can elastically swing with the end of the elastic element 300 abutting against the housing 100 as the contact point, thus achieving elastic contact with the button module 200. In this embodiment, the elastic element 300 is an elastic metal sheet.

[0046] Furthermore, one end of the adjusting member 400 can abut against any position between the two ends of the elastic member 300. By abutting against different positions of the elastic member 300, the swing distance of the elastic member 300 can be changed, thereby achieving elastic adjustment of the elastic member 300 and adjusting the pressing elasticity of the button module 200. The other end of the adjusting member 400 can abut against the housing 100 or the button module 200, both of which can change the elastic swing distance of the elastic member 300, thereby achieving adjustment of the pressing elasticity of the button module 200. The abutting position of the other end of the adjusting member 400 is not specifically limited here.

[0047] For details, please refer to the appendix. Figure 3 The elastic member 300 includes a first inclined segment 310, a second inclined segment 320, and a first abutting segment 330. Both the first inclined segment 310 and the second inclined segment 320 extend inclinedly from one end of the elastic member 300 toward the keyboard 1000 module. The first inclined segment 310 is close to the side of the housing 100, and the elastic abutting of the elastic member 300 is achieved by the inclined arrangement between the first inclined segment 310 and the second inclined segment 320.

[0048] Furthermore, the first abutting section 330 is located between the first inclined section 310 and the second inclined section 320, and the first abutting section 330 is used for the adjustment member 400 to abut against. When one end of the adjustment member 400 abuts against the first abutting section 330 and the other end abuts against the housing 100, the button module 200 reciprocates through the second inclined section 320. Compared with the first inclined section 310 and the second inclined section 320, its pressing elasticity is greatly increased, and the pressing force required is greater. When one end of the adjustment member 400 abuts against the first abutting section 330 and the other end abuts against the button module 200, the button module 200 reciprocates through the first inclined section 310. Compared with the first inclined section 310 and the second inclined section 320, its pressing elasticity is greatly increased, and the pressing force required is greater.

[0049] In this embodiment, the elastic member 300 further includes a third inclined segment 340 and a second abutting segment 350. The third inclined segment 340 extends inclinedly from one end of the elastic member 300 toward the keyboard 1000 module. The first inclined segment 310, the second inclined segment 320 and the third inclined segment 340 realize the inclined elastic abutting of the elastic member 300.

[0050] The second inclined section 320 is located between the third inclined section 340 and the first inclined section 310, and the second abutting section 350 is located between the second inclined section 320 and the third inclined section 340. The second abutting section 350 is used for the adjustment member 400 to abut against. The adjustment member 400 can switch and adjust the elastic force of the elastic member 300 acting on the button module 200 by disengaging from the elastic member 300, abutting against the first abutting section 330 or abutting against the second abutting section 350, so as to adjust the required rebound pressing force when the user presses.

[0051] When the adjusting member 400 is disengaged from the elastic member 300, the required rebound pressing force for the user when pressing is minimal relative to the abutting elastic member 300; when the adjusting member 400 abuts against the first abutting member, the required rebound pressing force for the user when pressing is smaller relative to the abutting section 350.

[0052] Furthermore, the keyboard 1000 module is provided with a first mounting position 210 for mounting the elastic element 300, and the housing 100 is provided with a second mounting position 110 for mounting the elastic element 300; the elastic element 300 is fixedly mounted through the first mounting position 210 and the second mounting position 110, thereby achieving elastic contact with the key module 200.

[0053] The first mounting position 210 and the second mounting position 110 are arranged facing each other. The first mounting position 210 is connected to the elastic element 300 by a positioning post, and the second mounting position 110 is fixedly connected to the elastic element 300 by a fixing screw. When disassembling, since the first mounting position 210 and the second mounting position 110 are arranged facing each other, the two mounting positions can be disassembled only through the installation gap between the elastic element 300 and the button module 200 and the housing 100. There is no need to disassemble the other side of the button module 200, which improves the convenience of disassembly and assembly.

[0054] Specifically, the housing 100 is provided with a fixing position 120 for the adjustment member 400 to abut against, and there are one or more fixing positions 120; the one or more fixing positions 120 are spaced apart from one end of the elastic member 300 along the other end of the elastic member 300; the adjustment and installation of the adjustment member 400 on the housing 100 is realized through different fixing positions 120, so as to realize the abutment of the elastic member 300 at different positions and change the abutment elastic force of the elastic member 300.

[0055] In this embodiment, there are two fixed positions 120, and the two fixed positions 120 are arranged in a relatively cooperative manner with the first abutting section 330 and the second abutting section 350. The adjusting member 400 can realize the elastic adjustment of the button module 200 by abutting the first abutting section 330 or the second abutting section 350 and abutting the corresponding fixed position 120.

[0056] The first inclined segment 310, the second inclined segment 320, and the third inclined segment 340 are all set at an angle to the horizontal plane, with the angle being 5-25 degrees. This avoids excessive differences in the inclination angles between different inclined segments, which could affect the stability of the elastic element 300 structure. Preferably, the angle is 10-20 degrees, which satisfies the inclined elastic contact while avoiding excessive inclination angles that could affect the internal installation space of the housing 100. In this embodiment, the inclination angles of the first inclined segment 310 are 13.9 degrees, 10.7 degrees, and 12.8 degrees, respectively. This ensures a smooth transition of the pressing elastic force of different inclined segment combinations when the adjusting element 400 is adjusted, avoiding excessive pressure elastic force differences between adjacent adjusting segments.

[0057] Furthermore, the elastic member 300 also includes a fixed section 360 fixed to the housing 100. The fixed section 360 extends horizontally from one end of the elastic member 300 away from the side of the first inclined section 310 away from the second inclined section 320. A reinforcing rib 370 is provided at the angle between the first inclined section 310 and the fixed section 360. The reinforcing rib 370 is provided to improve the elastic bending strength between the first inclined section 310 and the fixed section 360. Since the swing force of the first inclined section 310 is greater than that of the second inclined section 320 or the third inclined section 340 when the adjusting member 400 is not added, the service life of the elastic member 300 is further improved by providing the reinforcing rib 370.

[0058] Specifically, the first abutting section 330 is horizontally arranged, and the second abutting section 350 is a boss-shaped protrusion facing the housing 100. The abutting side of the boss and the abutting side of the first abutting section 330 are located on the same horizontal plane. This allows the adjusting member 400 of the same size to be adapted and switched between the first abutting section 330 and the second abutting section 350. The boss is a strip-shaped bent structure, which ensures that the elastic member 300 abuts elastically while abutting the adjusting member 400.

[0059] In some embodiments of the present invention, the keyboard 1000 further includes a buffer pad 500, which is installed between the key module 200 and the housing 100 to further increase the elastic adjustment and adaptability between the key module 200 and the housing 100. The buffer pad 500 can be one or more layers. In this embodiment, the buffer pad 500 is made of foam material.

[0060] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
