Description

TECHNICAL FIELD

[0001] The utility model relates to key technology field especially relates to a key structure. BACKGROUND

[0002] With the acceleration of the process of information society, computer systems have become the core carrier of modern office and personal life. As an important medium of human-computer interaction, the input performance of the keyboard is directly related to the information transmission efficiency. In the conventional physical keyboard system, the visual recognition degree of the key surface characters is a key factor affecting the operation accuracy, especially in low-illumination use scenarios, the traditional character marking scheme faces significant challenges.

[0003] For the character visibility problem in dark light environment, the current mainstream solution adopts a layered light guide technology architecture. The specific implementation is to integrate a micro LED light source at each mechanical switch contact point of the PCB substrate, and through a transparent light guide element formed by precise injection molding, the bottom light source radiation is conducted to the surface keycap area. This optical transmission system can theoretically achieve uniform illumination of the character area, but in actual application, there are two technical bottlenecks: first, due to the transmission distance (usually up to 10-15mm) formed by the mechanical shaft height, even if high refractive index optical materials are used, the light flux attenuation rate in the transmission process still exceeds 60%; second, the modular assembly process of the light guide element involves a precise positioning process, and the material cost of a single product increases by about 0.3-0.5 dollars, and an additional 0.25 standard working hours / unit is required for the assembly link, significantly increasing the overall manufacturing cost.

[0004] This technical limitation makes it difficult for the terminal product to achieve the ideal lighting effect in the real use scenario, and user research data shows that about 38% of users still have difficulty in character recognition in an environment with less than 50 lux of illumination. At the same time, due to the optical loss characteristics of the light guide element, manufacturers have to use higher power LED modules for compensation, which in turn increases the energy cost by about 15%, forming a vicious cycle of technical iteration.

[0033] As shown in Figures 1 to 5 The utility model discloses a key structure, including base 2 and presser 1, base 2 is equipped with the installation frame 4 of top opening, presser 1 is embedded in installation frame 4, and can be axially pressed relative to installation frame 4, presser 1 includes top plate portion 11 and the plurality of side plate portions 12 along the side peripheral surface of top plate portion 11 extends, and top plate portion 11 and the plurality of side plate portions 12 are enclosed and form a light emitting cavity 5, and top plate portion 11 is made of transparent material, and the light in the light emitting cavity 5 is diffused to top plate portion 11 by light source incidence.

[0034] The installation frame 4 of top opening provided on the base 2 provides a specific space for the installation of the presser 1. The presser 1 is embedded in the installation frame 4 and can be axially pressed relative to the installation frame 4. The presser 1 includes a top plate portion 11 and a plurality of side plate portions 12 extending along the side peripheral surface of the top plate portion 11. If the key is circular, the side plate portions 12 are a plurality of arc-shaped plates uniformly distributed around the side peripheral surface of the top plate portion 11. If the key is square, the side plate portions 12 are four rectangular plates connected to the four sides of the top plate portion 11, respectively. These side plate portions 12 and the top plate portion 11 enclose a light emitting cavity 5. The top plate portion 11 is made of transparent material, such as commonly used transparent plastic material acrylic, which has good light transmission. When the light source (such as an LED lamp) on the keyboard emits light, the light is incident into the light emitting cavity 5. Due to the special structure of the light emitting cavity 5, the light is reflected, refracted and diffused multiple times in the light emitting cavity 5 and finally diffused to the top plate portion 11 and transmitted out.

[0035] By embedding the pressing piece 1 in the mounting frame 4, and the pressing piece 1 being provided with the light-emitting cavity 5 and the top plate part 11 being made of transparent material, the light guide column does not need to be additionally produced. This saves certain material cost and reduces the production process. At the same time, the problem of light flux attenuation caused by the light guide column is avoided, the light transmittance of the key is ensured, the key is brighter and more uniform when emitting light, and the user experience is improved.

[0036] In an embodiment, as shown in Figure 4 The base 2 includes a plurality of side parts 21 arranged in a closed manner, and at least one of the plurality of side parts 21 is provided with an outwardly protruding buckle 2111.

[0037] The base 2 is arranged in a closed manner by a plurality of side parts 21, and these side parts 21 jointly build an installation frame 4. In this embodiment, taking a square key as an example, the base 2 is closed by four side parts 21 connected end to end, and the adjacent side parts 21 can be connected in a vertical manner to ensure that the installation frame 4 is regular in shape and stable in structure. In a circular key structure, the side parts 21 are a plurality of arc-shaped plates uniformly spliced to form a circular installation frame 4.

[0038] Among the plurality of side parts 21, at least one of the side parts 21 is provided with an outwardly protruding buckle 2111. In this embodiment, among the four side parts 21 of the square key base 2, the left and right two side parts 21 are both provided with buckles 2111, the buckles 2111 can be integrally formed on the side parts 21 in a plastic material, and the buckles 2111 protrude outward from the outer surface of the side parts 21 by a certain length. In actual application, the keyboard is provided with a clamping groove, by clamping the buckle 2111 on the side part 21 of the base 2 into the clamping groove, the key structure can be conveniently fixed on the keyboard to realize quick disassembly and assembly.

[0039] In an embodiment, as shown in Figure 4 The side part 21 is provided with a cutout 212 corresponding to the position where the buckle 2111 is arranged, and the lower side of the cutout 212 extends to the upper side of the cutout 212 and is provided with a buckle mounting plate 211, the left side, the right side and the upper side of the buckle mounting plate 211 are all spaced apart from the left side, the right side and the upper side of the cutout 212, and the buckle 2111 is arranged on the outer side of the buckle mounting plate 211.

[0040] When a snap fastener 2111 needs to be installed on a certain side panel 21, a cutout 212 is made at the corresponding position on that side panel 21. This cutout 212 can be a regular rectangular shape, and its size and shape are determined according to the actual size of the snap fastener 2111 to be installed and the design of the mounting plate. The snap fastener mounting plate 211 extends from the lower side to the upper side of the cutout 212. There are gaps between the left, right, and upper sides of the snap fastener mounting plate 211 and the corresponding left, right, and upper sides of the cutout 212. This means that the snap fastener mounting plate 211 does not completely fit inside the cutout 212, but has certain gaps in three directions. The snap fastener 2111 is set on the outer side of the snap fastener mounting plate 211. The snap fastener 2111 is fixed to the outer side of the snap fastener mounting plate 211 by integral molding.

[0041] The presence of the space between the clips allows the mounting plate 211 to have a certain degree of elastic deformation. When the key structure is installed on the device, if the clip 2111 is subjected to a certain external force, the mounting plate 211 can buffer the external force through the elastic deformation allowed by these space between the clips, preventing the clip 2111 from easily breaking due to rigid connection. Secondly, during the installation process, this structure can better adapt to the slight dimensional differences in the slots on different keyboards, improving the universality and adaptability of the key structure installation.

[0042] In one embodiment, at least one of the latch 2111 and the latch mounting plate 211 has elasticity. Specifically, when the latch 2111 has elasticity, when the button structure is installed into the device slot, the latch 2111 can undergo elastic deformation when squeezed by the edge of the slot, allowing the hook to slide smoothly into the slot. Subsequently, the latch 2111 returns to its original shape, tightly locking the slot, achieving a secure installation. If the latch mounting plate 211 has elasticity, during the installation process, when the latch 2111 is subjected to lateral squeezing force from the slot, the latch mounting plate 211 can undergo a certain degree of bending deformation within the space interval through its own elasticity, thereby buffering external forces and protecting the latch 2111 from damage. If both the latch 2111 and the latch mounting plate 211 have elasticity, their cooperation can further improve the convenience and stability of installation.

[0043] In one embodiment, such as Figure 4 As shown, the outer side of the buckle mounting plate 211 is parallel to the outer side of the side portion 21. The buckle 2111 protrudes from the outer side of the buckle mounting plate 211. The buckle 2111 has a triangular cross-section. One side of the buckle 2111 is fixed parallel to the side portion 21.

[0044] The outer side of the buckle mounting plate 211 is arranged in parallel with the outer side of the side part 21. This parallel relationship makes the overall structure neat and coordinated in appearance, and also provides convenience for subsequent installation operations. For example, when the key structure is installed on the keyboard, the parallel outer side of the buckle mounting plate 211 does not hinder the installation, ensuring the flatness of the installation.

[0045] The buckle 2111 protrudes from the outer side of the buckle mounting plate 211, and the cross section is triangular. In the actual installation scenario, when the key structure is matched with the card slot on the keyboard, the hypotenuse of the triangular buckle 2111 first contacts the edge of the card slot. Due to the structural characteristics of the triangle, when subjected to extrusion by the edge of the card slot, the extrusion force can be dispersed along the hypotenuse, which can more effectively resist external force and avoid deformation or damage of the buckle 2111 during installation. At the same time, when the buckle 2111 is completely buckled into the card slot, the triangular shape can provide a larger contact area and friction, enhancing the stability of the key structure after installation, so that it is not easy to come out of the card slot.

[0046] In an embodiment, the cross-sectional shape of the buckle 2111 can be trapezoidal. The trapezoidal buckle 2111 also has certain mechanical advantages, which can disperse the extrusion force during installation, and the side of the trapezoid can also provide a larger contact area and friction after being buckled into the card slot.

[0047] In an embodiment, as shown in Figure 4 The bottom of the mounting frame 4 is provided with an opening 42.

[0048] In this embodiment, the base 2 is surrounded by four side parts 21 connected vertically to form a mounting frame 4. At this time, the four edges of the bottom of the mounting frame 4 are not closed, thereby forming a bottom opening 42. This opening 42 can be a regular square opening 42, and the side length is matched with the internal size of the mounting frame 4.

[0049] In actual application scenarios, when the key structure is applied to the keyboard, the bottom opening 42 can provide a more convenient path for light propagation. For example, the light source inside the keyboard is arranged below the key structure, and the light can directly enter the light emitting cavity 5 of the pressing piece 1 through the opening 42 at the bottom of the mounting frame 4, further reducing the possibility of light being blocked or reflected during propagation. Compared with the structure in which the bottom of the mounting frame 4 is closed, the bottom opening 42 can make more light enter the light emitting cavity 5 efficiently, thereby enhancing the light transmission effect of the key, making the key brighter and clearer when emitting light, and improving the user's visual experience.

[0050] In an embodiment, as shown in Figures 3 to 5As shown, a pressing auxiliary assembly 3 is arranged between the base 2 and the pressing piece 1, the pressing auxiliary assembly 3 comprises an elastic reset piece 31, a guide sliding groove 32 and a limiting sliding block 33, the elastic reset piece 31 and the guide sliding groove 32 are vertically arranged, the guide sliding groove 32 is arranged on the inner side wall of the mounting frame 4, the limiting sliding block 33 is arranged on the side plate part 12, the limiting sliding block 33 is in sliding fit with the guide sliding groove 32, when the elastic reset piece 31 is compressed, the top of the elastic reset piece 31 abuts against the pressing piece 1, and the bottom of the elastic reset piece 31 abuts against the base 2.

[0051] The pressing auxiliary assembly 3 adopts an element with elastic recovery ability such as a spring. In the embodiment, the pressing auxiliary assembly 3 is a column coil spring.

[0052] The elastic reset piece 31 is vertically arranged, which ensures that it provides stable elastic force in the vertical direction. When the user presses the pressing piece 1, the elastic reset piece 31 is compressed to store elastic potential energy; and when the user releases the pressing piece 1, the elastic reset piece 31 pushes the pressing piece 1 back to the initial position by virtue of the elastic recovery force, thereby realizing the automatic reset function of the key.

[0053] The guide sliding groove 32 is arranged on the inner side wall of the mounting frame 4. In the embodiment, the guide sliding grooves 32 are arranged on the front and rear inner side walls of the mounting frame 4, the front and rear guide sliding grooves 32 are staggered with the left and right buckles 2111 to improve the rationality of the layout. The shape of the guide sliding groove 32 can be a rectangular groove, and the width and depth thereof are accurately designed according to the size of the limiting sliding block 33 to ensure that the limiting sliding block 33 can smoothly and stably slide therein. The limiting sliding block 33 is arranged on the side plate part 12 of the pressing piece 1, and correspondingly, the front and rear side plate parts 12 of the pressing piece 1 are provided with

[0054] The limiting sliding block 33. The limiting sliding block 33 is integrally formed with the side plate part 12, and the shape of the limiting sliding block 33 is matched with that of the guide sliding groove 32, for example, when the guide sliding groove 32 is rectangular, the limiting sliding block 33 can be designed as a rectangular block, and the size thereof is slightly smaller than the internal size of the guide sliding groove 32 to realize accurate sliding fit. When the pressing piece 1 is pressed by external force, the limiting sliding block 33 slides downward along the guide sliding groove 32, which ensures that the pressing piece 1 can only move smoothly along the vertical direction, avoiding shaking or deviation, thereby ensuring the accuracy and stability of the key operation. At the same time, the limiting effect of the guide sliding groove 32 on the limiting sliding block 33 also prevents the pressing piece 1 from being separated from the mounting frame 4 when it is not pressed.

[0055] The stable elastic force provided by the elastic reset piece 31 makes the key have clear feedback, so that the user can clearly perceive the pressed and released states of the key when operating. The cooperation of the guide sliding groove 32 and the limiting sliding block 33 ensures the smoothness and accuracy of the movement of the pressing piece 1, effectively improves the service life of the key, and reduces the wear of the components caused by shaking or deviation in the pressing process.

[0056] In one embodiment, such as Figure 5 As shown, the side plate portion 12 has a guide hole 121 with a bottom opening at a position near its side edge, and the upper end of the elastic reset member 31 passes through the guide hole 121.

[0057] The guide hole 121 has an open bottom and is typically designed to be circular. Its diameter is determined by the upper dimension of the elastic reset component 31 it mates with. During actual assembly, the upper end of the spring is inserted into the guide hole 121. When the user presses the button, the pressing component 1 moves downwards, causing the side plate 12 to move downwards as well. At this time, the guide hole 121 also moves downwards, compressing the elastic reset component 31 and storing elastic potential energy. When the user releases the button, the elastic reset component 31 returns to its original shape using its stored elastic potential energy, pushing the pressing component 1 upwards. In this process, the guide hole 121 provides excellent guidance for the upper end of the elastic reset component 31, ensuring that the spring maintains a vertical movement during compression and rebound, preventing tilting or twisting of the spring, thus ensuring the accuracy and stability of the button reset action.

[0058] In one embodiment, such as Figure 4 As shown, a positioning post 41 is provided at the corner of the mounting frame 4, and the lower end of the elastic reset member 31 is sleeved on the positioning post 41.

[0059] In this embodiment, positioning posts 41 are provided at the four corners of the mounting frame 4. The positioning posts 41 are generally cylindrical. When the user operates the button, the pressing member 1 moves downward under external force, and the elastic reset member 31 is compressed accordingly. At this time, since the lower end of the elastic reset member 31 is fitted onto the positioning post 41, the positioning post 41 effectively restricts the horizontal displacement of the elastic reset member 31, ensuring that it can only be compressed vertically, thus guaranteeing the uniformity and stability of the force. When the user releases the button, the elastic reset member 31 returns to its original shape, pushing the pressing member 1 back to its original position. The positioning post 41 continues to play a positioning role, ensuring that the rebound path of the elastic reset member 31 is accurate, thereby ensuring the stability and accuracy of the button reset action.

[0060] In one embodiment, such as Figure 5 As shown, the lower end of the limiting slider 33 is provided with a hook-shaped part 331 protruding outward from the side plate part 12, and the hook-shaped part 331 is provided in the guide groove 32.

[0061] The limiting sliding block 33 is integrally formed with the hook-shaped part 331. The hook-shaped part 331 protrudes from the lower end of the limiting sliding block 33 to the outside of the side plate part 12, and has a shape similar to a fishhook and a certain bending curvature. When the user presses the key, the pressing piece 1 drives the limiting sliding block 33 to move downward along the guide sliding groove 32. Since the hook-shaped part 331 is in the guide sliding groove 32, it can prevent the limiting sliding block 33 from being taken out of the guide sliding groove 32, and ensure that the pressing piece 1 can only move smoothly in the vertical direction. At the same time, the cooperation of the hook-shaped part 331 and the guide sliding groove 32 can also resist the lateral force to a certain extent, so as to avoid the shaking or deviation of the pressing piece 1 during the pressing process. In this way, the design greatly improves the stability and accuracy of the key operation. The cooperation of the hook-shaped part 331 and the guide sliding groove 32 makes the pressing piece 1 maintain a stable movement track during the entire pressing and rebounding process, and provides a good operation feeling for the user. At the same time, it effectively avoids the key failure caused by the shaking or deviation of the pressing piece 1, and improves the reliability and service life of the key structure.

[0062] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can easily think of various equivalent modifications or replacements within the technical range disclosed by the present application, and these modifications or replacements should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
