[0045] The utility model will be described in further detail below in conjunction with the drawings and embodiments. It is particularly pointed out that the following embodiments are only used for illustrating the utility model, but do not limit the scope of the utility model. Similarly, the following embodiments are only part of the embodiments of the utility model rather than all the embodiments, and all other embodiments obtained by the ordinary skilled in the art without creative labor belong to the scope of protection of the utility model.

[0046] Please see Figure 1 The embodiment provides a detachable keyboard of multi-support structure polymerization, including base 1, base plate assembly 2 and support assembly 3, base 1 has first reserved adjustment part 11;Base plate assembly 2 is embedded on base 1, and base plate assembly 2 is detachably connected with base 1, and base plate assembly 2 includes positioning plate 21 and PCB board 22, and PCB board 22 is arranged below positioning plate 21, and the second reserved adjustment part 211 is arranged on positioning plate 21, and the first reserved adjustment part 11 is consistent with the second reserved adjustment part 211;Support assembly 3 is sleeved on the second reserved adjustment part 211, so that the second reserved adjustment part 211 is in abutment with the first reserved adjustment part 11, and the support assembly 3 is detachably connected with the second reserved adjustment part 211.

[0047] In the embodiment, base 1 is the basic bearing structure of the keyboard, which is usually made of metal or high-strength plastic, and the top of which is provided with the first reserved adjustment part 11, which is preferably a standardized geometric slot hole penetrating or recessed, for providing the positioning reference of the base plate assembly 2 and the mounting interface of the support assembly 3.

[0048] The base plate assembly 2 is composed of the positioning plate 21 and the PCB board 22, the positioning plate 21 is embedded on the surface of the base 1 and can be detachably connected through screws or buckles, and the material is preferably metal or hard composite material, for fixing the key shaft body. The edge of the positioning plate 21 is provided with the second reserved adjustment part 211, which forms a spatial complementary relationship with the first reserved adjustment part 11 of the base 1, and the two are accurately aligned through geometric matching.

[0049] The support assembly 3 is made of non-metallic material and has a certain buffering performance, which can be rigidly supported by hard plastic or elastically buffered by soft plastic, silica gel and other materials. The inner wall of the support assembly 3 is in interference fit with the second reserved adjustment part 211, and the outer edge is in contact with the first reserved adjustment part 11 to form a multi-stage mechanical transmission path. By replacing the support assembly 3 of different materials or sizes, the connection stiffness and vibration attenuation characteristics between the positioning plate 21 and the base 1 can be changed, while ensuring the detachability and assembly stability between the components.

[0050] The embodiment effectively solves the retrofitting limitation problem of the traditional detachable keyboard caused by the fixed connection structure of the positioning plate 21 and the base 1 through the cooperative design of the open support assembly 3 and the standardized adjustment part. The geometric matching structure of the first reserved adjustment part 11 and the second reserved adjustment part 211 provides a standardized mounting interface for the support assembly 3. Different buffer performance materials such as hard plastic, soft plastic or silica gel can be selected according to the needs. By replacing the assembly set on the second reserved adjustment part 211, the connection stiffness and vibration conduction characteristics between the positioning plate 21 and the base 1 can be accurately adjusted. The interference fit design of the support assembly 3 and the adjustment part not only guarantees the stability of the multi-stage mechanical conduction path, but also maintains the detachability of the assembly, so that the user can flexibly stack or replace third-party buffer components on the basis of retaining the original assembly function, break through the single limitation of the traditional built-in buffer pad, realize the continuous touch adjustment from rigid support to elastic buffer, and at the same time ensure the overall assembly precision and long-term use reliability of the base plate assembly 2 and the base 1.

[0051] In some embodiments, the base 1 is provided with a first mounting groove, the base plate assembly 2 is embedded in the first mounting groove, the first reserved adjustment part 11 is a second mounting groove, the second mounting groove is distributed along the circumference of the first mounting groove, and the second mounting groove is in communication with the first mounting groove.

[0052] In the embodiment, the first mounting groove of the base 1 provides a main bearing cavity for the base plate assembly 2, ensuring the stability of the planar positioning of the positioning plate 21 and the PCB plate 22; the second mounting groove distributed along the circumference of the first mounting groove and in communication with the first mounting groove serves as the first reserved adjustment part 11, forming a surrounding support interface array, so that the support assembly 3 can be distributed in multiple points along the edge of the base plate assembly 2, significantly improving the torsional resistance of the connection structure. The geometric complementary relationship between the second reserved adjustment part 211 and the second mounting groove, combined with the interference fit design of the support assembly 3, not only realizes the vertical limiting between the positioning plate 21 and the base 1, but also allows the installation density or combination mode of the support assembly 3 to be flexibly adjusted according to the touch demand through the spatial continuity of the communication groove. When the hard plastic support assembly 3 is selected, the key vibration conduction can be suppressed through multiple-point rigid contact; when the soft plastic or silica gel material is used, the impact energy can be absorbed by elastic deformation, and the multi-groove communication structure facilitates the addition of third-party buffer components to adjacent grooves while retaining the original support assembly 3, realizing customized touch adjustment of rigid and flexible combination.

[0053] The embodiment maintains the quick disassembly and assembly characteristics of the base plate assembly 2, and the hierarchical layout of the first mounting groove and the second mounting groove expands the spatial configuration freedom of the support assembly 3, solving the poor retrofit compatibility problem of the traditional single-point buffer structure.

[0054] Please refer to Figure 2In some embodiments, the second reserved adjustment part 211 is a flange extending outward from the positioning plate 21, and the second reserved adjustment part 211 is provided with at least one first positioning hole 212, and the support assembly 3 is detachably connected with the second reserved adjustment part 211 through the first positioning hole 212.

[0055] In the embodiment, the second reserved adjustment part 211 is a flange structure extending outward from the positioning plate 21, which is used to form an interface matched with the first reserved adjustment part 11 of the base 1. The first positioning hole 212 provided on the second reserved adjustment part 211 is a standardized hole passing through the flange, which can be an open hole or a closed hole, and is preferably an open hole to simplify the disassembly and assembly operation of the support assembly 3. The first positioning hole 212 is used to fix the connecting end of the support assembly 3 and constrain the radial displacement thereof. The support assembly 3 is detachably connected with the second reserved adjustment part 211 through the first positioning hole 212 by a connecting member such as a bolt or a buckle, and the material thereof can be selected from hard plastic to provide rigid support, or elastic material such as soft plastic and silica gel to realize energy absorption and buffering. By replacing the support assembly 3 made of different materials, the mechanical transmission characteristics between the positioning plate 21 and the base 1 can be adjusted, and the open hole design facilitates the user to add a third-party buffering component, thereby improving the modification compatibility.

[0056] Please refer to Figure 2 In some embodiments, the support assembly 3 comprises a first buffering plate 31 and two first fixing blocks 32. The first buffering plate 31 is provided with first positioning columns 311 matched with the first positioning holes 212, and the number of the first positioning columns 311 corresponds to the number of the first positioning holes 212. The two first fixing blocks 32 are oppositely arranged at the two ends of the first buffering plate 31, and the first fixing block 32 is arranged between the second reserved adjustment part 211 and the second mounting groove.

[0057] In the embodiment, the first buffering plate 31 is an elastic supporting component arranged below the second reserved adjustment part 211, which can be made of polyurethane or silica gel, and the surface thereof is provided with the first positioning columns 311 corresponding to the number of the first positioning holes 212, which are used to be embedded in the hole positions to realize the axial positioning with the second reserved adjustment part 211. The first buffering plate 31 and the first fixing block 32 can also be integrally formed to improve the assembly reliability.

[0058] Two first fixed blocks 32 are symmetrically arranged at both ends of the first buffer plate 31, and the main body is located between the second reserved adjusting part 211 and the second mounting groove of the base 1, used to fill the gap and conduct the pressure load. A cylindrical structure is provided on the first fixed block 32, which is matched with the pre-set guide hole of the first buffer plate 31 to form vertical limiting, and further, the top end of the cylinder can extend into the second mounting groove to constrain the transverse displacement. When the first buffer plate 31 needs to adjust the installation direction, it can also be placed above the second reserved adjusting part 211, at this time, the first fixed block 32 is matched with the inverted hole of the first buffer plate 31 through the cylinder, realizing the compatibility of two-way installation.

[0059] In this embodiment, the elastic material characteristics of the first buffer plate 31 realize the buffering and energy absorption of the pressure load, and the axial adaptation of the first positioning column 311 and the first positioning hole 212 ensures the accurate positioning of the positioning plate 21 and the base 1. The symmetrically distributed first fixed blocks 32 uniformly conduct the load to the second mounting groove of the base 1, and the double limiting design of the cylindrical structure and the buffer plate guide hole synchronously restricts the vertical and transverse displacement, improving the structural stability. The top end of the cylinder of the first fixed block 32 extending into the second mounting groove forms an embedded limiting interface, which strengthens the transverse anti-deviation ability.

[0060] Please refer to Figure 3 In some embodiments, a first reserved threaded hole is provided on the second mounting groove, and the support assembly 3 further includes a second buffer plate 33, two second fixed blocks, and a first fastener 331. The second buffer plate 33 is provided with a first connecting hole and a first open slot, the first open slot is arranged towards the second reserved adjusting part 211 and matched with the second reserved adjusting part 211, and the first connecting hole penetrates the second buffer plate 33 from top to bottom and is matched with the first positioning hole 212. The two second fixed blocks are arranged at opposite ends of the second buffer plate 33, and the second fixed block is abutted between the second buffer plate 33 and the second mounting groove. The first fastener 331 penetrates the first connecting hole, the first positioning hole 212 and the first reserved threaded hole in sequence to lock the second buffer plate 33 on the second mounting groove.

[0061] In this embodiment, the second buffer plate 33 is a rigid bearing component with a first open slot, the open slot extends towards the second reserved adjusting part 211 and matches the outer contour of the second reserved adjusting part 211, used to be sleeved on the second reserved adjusting part 211. The first connecting hole penetrates the second buffer plate 33 vertically and is coaxially aligned with the first positioning hole 212, forming a through-type fastening channel. The two second fixed blocks are cylindrical elastic bodies, which can be made of rubber or silicone material, and are symmetrically pressed between the end of the second buffer plate 33 and the side wall of the second mounting groove, absorbing vibration energy and dispersing local stress by deformation. The first fastener 331 penetrates the first connecting hole, the first positioning hole 212 and the first reserved threaded hole in sequence, and after being tightened, the second buffer plate 33, the second reserved adjusting part 211 and the base 1 form a rigid connection.

[0062] The embodiment ensures stable load transmission through the rigid structure of the second buffer plate 33, the first opening slot is matched and sleeved with the outer contour of the second reserved adjusting part 211, and precise limiting in the horizontal direction is realized. The through type alignment design of the first connecting hole and the first positioning hole 212 cooperates with the first fastener 331 to form multi-point rigid locking, thereby enhancing the overall connection strength. The second fixed block in the cylindrical shape is made of elastic material and is pressed between the buffer plate and the mounting groove, absorbs vibration impact by deformation, and uniformly disperses stress concentration, thereby avoiding local overload. After the first fastener 331 is locked, the second buffer plate 33, the second reserved adjusting part 211 and the base 1 form an integrated load-bearing frame, which takes into account the structural rigidity and dynamic buffering requirements, and effectively improves the impact resistance and long-term stability of the support assembly 3.

[0063] Please refer to Figure 4 In some embodiments, the second reserved adjusting part 211 is a flange extending outward from the positioning plate 21, and at least one second positioning hole 213 is arranged on the second reserved adjusting part 211, and the support assembly 3 is detachably connected with the second reserved adjusting part 211 through the second positioning hole 213.

[0064] In the embodiment, the second positioning hole 213 is arranged on the surface of the flange, and preferably, the second positioning hole 213 is an open structure, and the opening direction extends along the edge of the flange, thereby facilitating quick alignment and assembly of the support assembly 3. The support assembly 3 is connected with the second positioning hole 213 through a connecting member such as a bolt or a latch, thereby forming a detachable connection structure. When disassembling, the connecting member can be separated from the flange by only removing the connecting member, thereby realizing modular maintenance.

[0065] In the embodiment, the opening direction of the second positioning hole 213 extending along the edge of the second reserved adjusting part 211 is matched with the insertion track of the connecting member of the support assembly 3, thereby reducing the alignment accuracy requirement of the hole position during assembly, and realizing quick transverse insertion alignment. The open hole structure allows the connecting member to be transversely separated without being completely withdrawn during disassembly, thereby simplifying the disassembly steps and improving the maintenance efficiency. The detachable connection mode of the support assembly 3 and the second reserved adjusting part 211 facilitates independent replacement or maintenance of local components, thereby reducing the overall disassembly workload.

[0066] Please refer to Figure 5 In some embodiments, the support assembly 3 includes a third buffer plate 34, a fourth buffer plate 35 and a first fixed column 36. The fourth buffer plate 35 is arranged in a vertical direction spaced apart from the third buffer plate 34, and a first gap is formed between the third buffer plate 34 and the fourth buffer plate 35. The first gap is matched with the thickness of the second reserved adjusting part 211. The first fixed column 36 penetrates the fourth buffer plate 35, the second positioning hole 213 and the third buffer plate 34 in sequence from bottom to top, and the lower end of the first fixed column 36 extends downward and abuts in the second mounting groove.

[0067] In the embodiment, the third buffer plate 34 refers to a plate-shaped structure in the upper layer of the support assembly 3, which can be made of metal or composite material, and is used to bear the vertical load; the fourth buffer plate 35 is a plate-shaped component arranged in parallel in the lower layer, and the third buffer plate 34 and the fourth buffer plate 35 are spaced apart along the vertical direction to form a first gap, the gap spacing is designed to be accurately matched with the thickness of the second reserved adjusting part 211, so as to ensure that the adjusting part is embedded without deviation.

[0068] The first fixed column 36 is a cylindrical metal member, which penetrates the positioning hole of the fourth buffer plate 35, the second positioning hole 213 of the second reserved adjusting part 211 and the through hole of the third buffer plate 34 in turn from bottom to top, and the lower end extension part thereof abuts in the second mounting groove (i.e., the first reserved adjusting part 11) of the base 1, and is axially fixed by thread or interference fit. The clamping structure formed by the third buffer plate 34 and the fourth buffer plate 35 generates uniform pre-tightening force when the fixed column is locked, avoiding local stress concentration.

[0069] In the embodiment, the first gap formed by the third buffer plate 34 and the fourth buffer plate 35 along the vertical direction realizes accurate matching with the thickness of the second reserved adjusting part 211, so as to ensure that the adjusting part is embedded without deviation; the first fixed column 36 penetrates the fourth buffer plate 35, the second positioning hole 213 and the third buffer plate 34, and the lower end extension part thereof abuts the constraint of the second mounting groove, and forms stable axial fixation by thread or interference fit, so that the clamping structure formed by the third buffer plate 34 and the fourth buffer plate 35 generates uniformly distributed pre-tightening force when locked, avoiding deformation or wear of the parts caused by stress concentration; the support assembly 3 is designed to be adaptive through the first gap and the penetrating assembly of the fixed column, which not only ensures the reliable transmission of the vertical load, but also realizes the accurate limiting of the second reserved adjusting part 211 in the horizontal direction, and the modular connection structure is convenient for disassembly and maintenance, reducing the overall disassembly cost.

[0070] In some embodiments, the number of second positioning holes 213 is two; the number of third buffer plates 34, fourth buffer plates 35 and first fixed columns 36 corresponds to the number of second positioning holes 213 one by one; or the number of third buffer plates 34 and fourth buffer plates 35 is one, and the number of first fixed columns 36 corresponds to the number of second positioning holes 213 one by one.

[0071] Please refer to Figure 4 , the number of second positioning holes 213 is two, and the number of third buffer plates 34, fourth buffer plates 35 and first fixed columns 36 is two.

[0072] Please refer to Figure 5The number of the second positioning holes 213 is two, the number of the third buffer plates 34 and the fourth buffer plates 35 is one, and the number of the first fixed columns 36 is two.

[0073] The number of the second positioning holes 213 is two, the number of the third buffer plates 34 and the fourth buffer plates 35 is one, and the number of the first fixed columns 36 is two.

[0074] Please refer to Figure 6 In some embodiments, the number of the second positioning holes 213 is two; the support assembly 3 further comprises a buffer bottom plate 37, two fifth buffer plates 38, and two second fasteners 39. The buffer bottom plate 37 is arranged in the second mounting groove, and two buffer spacers 371 are arranged on the buffer bottom plate 37 in a staggered manner. The buffer spacers 371 are provided with second connecting holes coaxial with the second positioning holes 213.

Each second fastener 39 penetrates the buffer spacer 371, the fifth buffer plate 38, and the second positioning hole 213 arranged on the same side in sequence.

[0075] In the present embodiment, the buffer bottom plate 37 is used to bear the buffer spacers 371 and the fifth buffer plates 38. The buffer spacer 371 is a sheet-shaped component distributed on the buffer bottom plate 37 in a staggered manner. The second connecting holes formed on the surface of the buffer spacer 371 are coaxial with the second positioning holes 213 of the second reserved adjusting part 211, and the axis is ensured to coincide through precision machining. The fifth buffer plate 38 is an elastic element arranged between the buffer spacer 371 and the second positioning hole 213, which is used to absorb vibration and compensate for assembly tolerance. The second fastener 39 is a connecting piece penetrating the buffer spacer 371, the fifth buffer plate 38, and the second positioning hole 213 on the same side, which realizes rigid locking between multiple components through threads or buckling. The staggered layout of the buffer spacer 371 can disperse local stress, the elastic property of the fifth buffer plate 38 is suitable for the requirement of vertical load transmission, and the penetrating connection of the second fastener 39 ensures the integrity of the assembly.

[0076] The staggered design of the buffer bottom plate 37 and the buffer spacer 371, combined with the elastic support of the fifth buffer plate 38 and the penetration locking of the second fastener 39, forms a multi-stage buffer and rigid connection synergy, effectively disperses the vertical load and suppresses vibration transmission; The precise coaxial matching of the second connecting hole and the second positioning hole 213 ensures the installation alignment accuracy, avoiding the imbalance of the pre-tightening force caused by misalignment; The staggered arrangement of the buffer spacer 371 and the double fifth buffer plate 38 combination further balances the stress distribution, reduces the risk of local wear, and at the same time, the modular assembly structure facilitates quick disassembly and maintenance, improving system maintainability and service life.
