Description

Technical Field

[0001] This utility model relates to the field of keyboard technology, and in particular to a quick-release keyboard structure. Background Technology

[0002] In the current computer and electronic device market, the keyboard, as an important input device, has always been a focus for both manufacturers and users in terms of ease of design, maintainability, and production cost. With continuous technological advancements and increasing user demands for personalized and modular devices, quick-release keyboard designs are gradually becoming a new market trend. However, existing quick-release keyboard technologies have many shortcomings, especially in the method of removing the cover, which urgently needs improvement.

[0003] Existing quick-release keyboard designs typically involve removing the entire cover at once. While this design achieves the goal of rapid disassembly to some extent, it also introduces significant problems. Specifically, there are multiple contact surfaces between the cover and the main body. To ensure structural stability and durability, these contact surfaces often need to be designed to be relatively wide and thick, thus increasing the overall volume of the cover.

[0004] The increased size of the keyboard cover not only hinders the keyboard's slim and lightweight design, significantly compromising its portability and aesthetics, but also directly leads to increased production costs. On one hand, a larger cover requires more raw materials, increasing material costs; on the other hand, it necessitates more processes and more complex techniques during processing and assembly, further driving up manufacturing costs. Furthermore, the larger cover occupies more space during transportation and storage, increasing logistics and management costs.

[0005] Therefore, existing quick-release keyboard structures have not yet achieved an ideal balance between convenience, maintainability, and production costs. The market urgently needs a new type of quick-release keyboard structure that can achieve rapid and convenient disassembly while maintaining a slim and lightweight keyboard design, and simultaneously reduce production costs to meet users' demands for high-performance, low-cost electronic devices.

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a quick-release keyboard structure.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] This utility model provides a keyboard quick-release structure, including: a main body and a PCBA board, the main body having a connecting component on at least one side, the connecting component being detachably connected to a cover, the cover being used to fix the PCBA board to the main body.

[0009] In one specific embodiment, the connecting component includes at least one set of connecting portions, and the cover is provided with a snap-fit ​​portion corresponding to the connecting portions.

[0010] In one specific embodiment, the connecting part includes a lower contact ball groove and a male contact ball, the male contact ball being installed in the lower contact ball groove, and the snap-fit ​​part includes an upper contact ball groove and a female contact ball, the female contact ball being installed in the upper contact ball groove, and the female contact ball being detachably connected to the male contact ball.

[0011] In one specific embodiment, the upper end of the PCBA board is provided with a plurality of mounting protrusions, and the main body is located on the same horizontal line as the connecting part and is provided with mounting grooves corresponding to the mounting protrusions.

[0012] In one specific embodiment, the lower end of the PCBA board is further provided with a plurality of insertion protrusions, and the main body is provided with insertion slots corresponding to the insertion protrusions.

[0013] In one specific embodiment, the number of connecting parts is two sets.

[0014] In one specific embodiment, the main body is square-shaped, the connecting component is arranged along the length direction of the upper end of the main body, and the cover is strip-shaped.

[0015] In one specific embodiment, textured layers are also provided on both sides of the main body.

[0016] In one specific embodiment, the PCBA board is also connected to keycaps.

[0017] In one specific embodiment, both the main body and the cover are made of metal or plastic.

[0018] The advantages of this quick-release keyboard structure compared to existing technologies are as follows: by having the cover contact only one side of the main body, this design reduces the size of the cover, making the keyboard thinner and more compact while maintaining its original functionality.

[0033] See Figures 1 to 5 The specific embodiment shown in this utility model discloses a keyboard quick-release structure, including: a main body 10 and a PCBA board 20. The main body 10 is provided with a connecting component on at least one side. The connecting component is detachably connected to a cover 30. The cover 30 is used to fix the PCBA board 20 to the main body 10.

[0034] Specifically, the main body 10 is the basic frame of the keyboard, used to support and mount various keyboard components. The PCBA board 20 is the keyboard's circuit board assembly, integrating the keyboard's circuitry and electronic components. The cover 30 protects the PCBA board 20 and secures it to the main body 10. Connecting components are provided on at least one side of the main body 10; these components can be clips, bolts, slots, or any structure that enables a detachable connection. The cover 30 is detachably connected to the main body 10 via these connecting components. Crucially, the cover 30 only contacts one side of the main body 10, rather than multiple sides as in traditional designs. This design simplifies the structure of the cover 30, requiring only the fixation of the PCBA board 20 to one side of the main body 10.

[0035] In other words, by having the cover 30 contact only one side of the main body 10, this design reduces the size of the cover 30, making the keyboard thinner and more compact while maintaining its original functionality. This reduction in the size of the cover 30 not only improves the keyboard's portability and aesthetics but also significantly reduces production costs. Specifically, the smaller size of the cover 30 means less raw material is required, directly lowering material costs. Simultaneously, the simplified structure of the cover 30 makes the processing and assembly process simpler and more efficient, reducing the complexity of procedures and processes, further lowering manufacturing costs. More importantly, this quick-release structure still maintains the keyboard's maintainability. When the keyboard needs repair or component replacement, users can quickly remove the cover 30 with simple operations to easily access and replace internal components such as the PCBA board 20. This design improves repair efficiency and extends the keyboard's lifespan.

[0036] More specifically, one of the four sides of the main body 10 may be provided with a connecting component.

[0037] In other embodiments, connecting components may be provided on two corresponding sides of the four sides of the main body 10, that is, the number of cover 30 is 2.

[0038] See Figures 2 to 4 As shown, in one embodiment, the connecting component includes at least one set of connecting portions 11, and the cover 30 is provided with a snap-fit ​​portion 31 corresponding to the connecting portions 11.

[0039] Specifically, at least one set of connecting portions 11 is provided on at least one side (e.g., top, bottom, left, or right) of the keyboard body 10. Each connecting portion 11 includes a protruding structure, which can be cylindrical, square, or other regular or irregular shapes. The height of the protruding structure is determined according to actual needs, generally between 2-5 mm. Guide slopes with an angle of 30-60° can be provided on one or both sides of the protruding structure to allow the locking portion 31 to slide smoothly into and engage with the protruding structure. The locking portion 31 is provided on the cover 30 at a position corresponding to the connecting portion 11. The locking portion 31 has a groove structure that matches the protruding structure of the connecting portion 11. The depth of the groove is slightly greater than the height of the protruding structure of the connecting portion 11 by 0.5-1 mm to ensure the stability of the engagement. An inclined surface that mates with the guide slope of the connecting portion 11 can be provided at the entrance of the groove to facilitate the mating of the locking portion 31 with the connecting portion 11. Small elastic protrusions can be set inside the groove. These elastic protrusions can be made of elastic materials such as rubber or silicone to increase the friction of the snap-fit ​​and prevent the cover 30 from loosening during use.

[0040] In other words, the protruding structure of the connecting part 11 matches the groove structure of the snap-fit ​​part 31, enabling precise snap-fit. This precise snap-fit ​​method ensures accurate connection between the cover 30 and the main body 10, avoiding problems such as loosening or deformation of the cover 30 due to connection position deviation. For example, during keyboard use, frequent key presses generate vibration and impact; the precise snap-fit ​​connection effectively resists these external forces, ensuring a stable connection between the cover 30 and the main body 10. Furthermore, the elastic protrusion inside the groove of the snap-fit ​​part 31 increases the friction of the snap-fit, making the connection between the cover 30 and the main body 10 even stronger. Even under significant external force during use, the cover 30 is not easily loosened or detached. For example, when carrying the keyboard out, collisions or drops may occur; the additional friction provided by the elastic protrusion prevents the cover 30 from separating from the main body 10 due to vibration, protecting components such as the PCBA board 20 inside the keyboard.

[0041] See Figures 2 to 5 As shown, in one embodiment, the connecting part 11 includes a lower ball groove 111 and a male ball 112, the male ball 112 being installed in the lower ball groove 111. The snap-fit ​​part 31 includes an upper ball groove 311 and a female ball 312, the female ball 312 being installed in the upper ball groove 311, and the female ball 312 being detachably connected to the male ball 112.

[0042] Specifically, a lower strike plate groove 111 is formed on a selected side (such as the top or bottom) of the keyboard body 10 using injection molding, stamping, or other processes. The male strike plate 112 is made of metal (such as stainless steel) and has a certain degree of elasticity and hardness. The male strike plate 112 is placed in the lower strike plate groove 111, and its bottom is fixed to the bottom of the groove 111 with screws to ensure that it will not easily fall off. The top of the male strike plate 112 is a snap-fit ​​block for engaging with the female strike plate 312. An upper strike plate groove 311 is formed on the cover 30 in the same manner at the position corresponding to the connecting part 11. The female strike plate 312 is also made of metal, and its interior has a groove that matches the snap-fit ​​block on the top of the male strike plate 112. The groove has protrusions on both sides. The female contact ball 312 is placed into the upper contact ball groove 311 and fixed in the upper contact ball groove 311 by screws to ensure the stability and reliability of the female contact ball 312.

[0043] More specifically, pick up the cover 30 and align the snap-fit ​​portion 31 on the cover 30 with the connecting portion 11 on the main body 10. As the female contact bead 312 and the male contact bead 112 gradually approach each other, the protrusion in the groove of the female contact bead 312 is squeezed by the snap-fit ​​block on top of the male contact bead 112, resulting in a certain elastic deformation. As the cover 30 continues to be pressed down, the protrusion and the snap-fit ​​block engage, at which point a slight "click" sound will be heard, indicating that the cover 30 and the main body 10 have been successfully connected. Conversely, simply pull the cover 30 upwards to disassemble it.

[0044] See Figures 2 to 3 As shown, in one embodiment, the upper end of the PCBA board 20 is provided with a plurality of mounting protrusions, and the main body 10 is located on the same horizontal line as the connecting part 11 and is provided with mounting grooves 12 corresponding to the mounting protrusions.

[0045] Specifically, pick up the fabricated PCBA board 20 and align the mounting protrusions at its upper end with the mounting slots 12 on the main body 10. Gently place the PCBA board 20 on the main body 10, allowing the mounting protrusions to gradually insert into the mounting slots 12. During insertion, pay attention to the correspondence between the mounting protrusions and the mounting slots 12, ensuring that each mounting protrusion is accurately inserted into its corresponding mounting slot 12. Once all the mounting protrusions of the PCBA board 20 are inserted into the mounting slots 12, pick up the cover 30 and align the snap-fit ​​portion 31 on the cover 30 with the connecting portion 11 on the main body 10, causing the cover 30 to snap into the main body 10. During the snap-fit ​​process, the cover 30 will gradually press down on the mounting protrusions on the PCBA board 20, making the mounting protrusions more firmly fixed in the mounting slots 12, thereby fixing the PCBA board 20 to the main body 10.

[0046] In other words, the PCBA board 20 is doubly secured by the fitting of the mounting protrusion with the mounting groove 12 and the pressing action of the cover 30. The fitting of the mounting protrusion with the mounting groove 12 provides basic positioning and fixation, preventing the PCBA board 20 from moving horizontally; the pressing action of the cover 30 further increases the stability of the PCBA board 20 in the vertical direction, preventing it from loosening or falling off due to vibration or external force. For example, during keyboard use, frequent key presses by the user will generate vibration; the doubly securing mechanism can effectively resist this vibration, ensuring the stable fixation of the PCBA board 20.

[0047] See Figures 2 to 3 As shown, in one embodiment, the lower end of the PCBA board 20 is provided with a plurality of insertion protrusions 21, and the main body 10 is provided with insertion slots corresponding to the insertion protrusions 21.

[0048] Specifically, the engagement of the insertion protrusion 21 with the insertion slot creates an additional limiting and fixing point at the lower end of the PCBA board 20. Combined with the fit between the upper mounting protrusion and the mounting slot 12, and the pressing action of the cover 30, multi-dimensional fixation of the PCBA board 20 is achieved. This multi-dimensional fixing method greatly enhances the stability of the PCBA board 20, effectively preventing its movement in the horizontal and vertical directions. For example, when the keyboard is subjected to a large external impact, the multi-dimensional fixing structure can better resist the external force, maintain the stability of the PCBA board 20, and avoid circuit failures caused by the movement of the PCBA board 20.

[0049] See Figures 2 to 4 As shown, in one embodiment, the number of connecting parts 11 is two sets.

[0050] Specifically, there are two sets of connecting parts 11, forming two connection points between the cover 30 and the main body 10. These two connection points distribute the connecting force between the cover 30 and the main body 10 to two different locations. Compared to a single connection point, the force borne by each connection point is relatively reduced, thereby lowering the risk of damage to a single connection point due to excessive force. For example, when the keyboard is subjected to external pressure or impact, the two connection points can jointly withstand the external force, making the connection between the cover 30 and the main body 10 more robust.

[0051] See Figures 2 to 5 As shown, in one embodiment, the main body 10 is square, the connecting component is arranged along the length direction of the upper end of the main body 10, and the cover 30 is strip-shaped.

[0052] Specifically, the connecting components arranged along the length of the upper end of the main body 10 ensure a uniform distribution of the connection force between the cover 30 and the main body 10. Furthermore, the square-shaped main body 10 and the strip-shaped cover 30 structure, combined with the rational layout of the connecting components, effectively prevent deformation of the cover 30 and the main body 10 under stress. The clamping action of the connecting components restricts the relative displacement between the cover 30 and the main body 10, making the entire keyboard structure more robust and durable. In addition, the combination of the strip-shaped cover 30 and the square-shaped main body 10, along with the connecting components arranged along the length, provides clear guidance for installation. Operators can easily align the cover 30 with the main body 10 and quickly complete the installation according to the layout of the connecting components. Compared to other complex connection methods, this design significantly shortens installation time and improves production efficiency.

[0053] See Figures 1 to 4 As shown, in one embodiment, textured layers 13 are also provided on both sides of the main body 10.

[0054] Specifically, regular geometric textures, such as stripes, diamonds, or grids, can be used. Taking stripes as an example, the direction of the texture can be perpendicular to the length of the main body 10. This way, when picking up and placing the keyboard, the contact surface between the fingers and the texture generates greater friction in the vertical direction, preventing the keyboard from slipping.

[0055] In other words, the presence of the textured layer 13 significantly increases the roughness of the surface of the main body 10, thereby increasing the friction between the fingers and the main body 10. When picking up and putting down the keyboard, the fingers can grip the main body 10 better, making it less likely to slip and improving safety during use. For example, on a smooth desktop, a keyboard with the textured layer 13 is easier to pick up steadily than a keyboard without the textured layer 13.

[0056] See Figures 1 to 3 As shown, in one embodiment, the PCBA board 20 is also connected to a keycap 40.

[0057] Specifically, the keycap 40 and the PCBA board 20 can be connected by mechanical or electrical means, both of which use existing publicly available technologies and will not be elaborated on here.

[0058] In one embodiment, both the main body 10 and the cover 30 are made of metal or plastic.

[0059] Specifically, metal materials possess high strength and hardness, enabling them to withstand significant external impacts and wear, thus making the keyboard body 10 and cover 30 more durable. For example, keyboards made of stainless steel can maintain good performance and appearance even in harsh environments, such as industrial settings. Furthermore, metal has excellent thermal conductivity, allowing it to quickly dissipate heat generated inside the keyboard, improving its stability and lifespan. This heat dissipation advantage is particularly pronounced during prolonged use or high-intensity operations.

[0060] The low density of plastic makes keyboards lightweight, making them easy to carry and use. Furthermore, the relatively low cost of raw materials and simple processing techniques of plastic reduce production costs. Additionally, plastic's good plasticity allows for the creation of complex shapes through injection molding, extrusion, and other processes, meeting diverse design requirements.

[0061] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
