[0002] A visual keyboard is an input device that combines visual display and keyboard functionality. By adding visual elements to the keyboard, it provides an intuitive way to operate a computer or other electronic device. This keyboard not only provides the input functions of a traditional keyboard, but also adds visual display elements such as LED indicators, LCD screens, or touchscreen technology, allowing users to more intuitively see the information on the keyboard, thereby improving operational efficiency and user experience.

[0003] The current method of fixing the keys of a visual keyboard usually uses adhesive backing to fix the key combination. The key combination is generally an integrated keycap and key. Due to the adhesive force of the adhesive backing, the key combination is difficult to design for positioning. The key combination cannot be positioned on the active surface during the assembly process, which can easily cause the overall key to be off-center and irreversible, affecting the appearance of the product. Utility Model Content

[0004] The purpose of the present invention is to provide a visual keyboard structure to solve the problems in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is to provide a visual keyboard key structure, including a front shell, a key assembly, a circuit board assembly, a display screen assembly and a rear shell, the front shell is provided with a plurality of clearance holes, adjacent clearance holes are arranged at intervals, and a positioning assembly is provided on the front shell; the key assembly is arranged below the front shell, including a key silica gel and a key cap, the key cap is arranged on the key silica gel, the key cap partially protrudes from the clearance hole, an adapter assembly is provided on the key silica gel, and the adapter assembly is positioned and connected to the positioning assembly; the circuit board assembly is arranged below the key silica gel and fits with the key silica gel, and the circuit board assembly is provided with a light-transmitting hole corresponding to the key cap; the display screen assembly is arranged below the circuit board assembly and is electrically connected to the circuit board assembly; the rear shell is arranged below the display screen assembly, is buckled and connected with the front shell, and a accommodating chamber is formed between the two.

[0006] Furthermore, the positioning component adopts a positioning column, the adapter component adopts a positioning hole, and the positioning column is inserted into the positioning hole.

[0007] Furthermore, there are multiple positioning holes, the button silicone has a square structure, and the positioning holes are provided at least at the corners of the button silicone. The positioning columns are the same in number as the positioning holes and are arranged correspondingly.

[0008] Furthermore, the plurality of the clearance holes are arranged in a matrix, the front shell is provided with support ribs, the support ribs separate the plurality of the clearance holes into a matrix arrangement, and the width of the support ribs provided between adjacent clearance holes is less than 1.2 mm.

[0009] Furthermore, the button silica gel includes a mounting body, the mounting body is provided with a button hole, the button hole is provided with a reset button drag, the reset button drag is provided with the button cap, and the supporting rib abuts against the mounting body.

[0010] Furthermore, the reset button is made of elastic material.

[0011] Furthermore, a touch portion is provided at the bottom of the reset button drag, and the touch portion can abut against the display screen assembly.

[0012] Furthermore, an exhaust groove is provided at the bottom of the mounting body, and the exhaust groove is communicated with the button hole.

[0013] Furthermore, the button cap is fully transparent or semi-transparent.

[0014] Furthermore, the circuit board assembly is provided with a positioning hanger, the display screen assembly is provided with a connecting piece, and the positioning hanger is adapted to the connecting piece.

[0015] The beneficial effects of the present invention are:

[0016] 1. In this application, by removing the adhesive backing, the phenomenon of the key assembly being irreversibly offset after being attached is avoided. A positioning component is provided on the front shell, and an adapter is provided on the key silicone. The adapter and positioning components are positioned and connected. This allows the key assembly to be adjusted and accurately positioned during assembly, facilitating installation of the key assembly while ensuring consistency in the appearance of the gap between the key assembly and the front shell after assembly.

[0017] 2. In the prior art, due to the adhesive backing, the effective bonding width of the adhesive backing must be greater than 1.2mm, otherwise it is easy to cause debonding. This results in excessive key spacing, which easily affects the expansion requirements of the product's refined and delicate appearance. In this application, by removing the adhesive backing, the width of the support ribs between adjacent clearance holes can be reduced to less than 1.2mm, and the minimum can be 0.5mm, which can significantly reduce the key spacing and allow the keyboard to be more refined and delicate.

[0018] 3. Since the width of the support ribs between adjacent clearance holes is less than 1.2mm, the distance between the support ribs and the reset button can be larger, ensuring that the reset button is not easily deformed and scratched against the side walls of the clearance holes in the front shell, thereby affecting the feel of pressing the button.

[0019] 4. By providing an exhaust groove at the bottom of the mounting body, the gas generated when the key cap is pressed is discharged out of the mounting body through the exhaust groove, thereby preventing the key cap from being unable to return to the mounting body due to air pressure when it returns to the mounting body.

[0030] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] Reference Figures 1 to 4 , as an embodiment of the present invention, a visual keyboard key structure is provided, which includes a front shell 1, a key assembly 2, a circuit board assembly 3, a display screen assembly 4 and a rear shell 5. The front shell 1 is provided with a plurality of makeshift holes 11, and adjacent makeshift holes 11 are arranged at intervals. A positioning assembly is provided on the front shell 1; the key assembly 2 is arranged at the bottom of the front shell 1, and includes a key silica gel 21 and a key cap 22. The key cap 22 is arranged on the key silica gel 21, and the key cap 22 partially protrudes from the makeshift hole 11. An adapter assembly is provided on the key silica gel 21, and the adapter assembly is positioned and connected with the positioning assembly; the circuit board assembly 3 is arranged below the key silica gel 21 and fits with the key silica gel 21. The circuit board assembly 3 is provided with a light-transmitting hole 31 corresponding to the key cap 22; the display screen assembly 4 is arranged below the circuit board assembly 3 and is electrically connected to the circuit board assembly 3; the rear shell 5 is arranged below the display screen assembly 4, is buckled and connected with the front shell 1, and a accommodating chamber 6 is formed between the two.

[0032] In this embodiment, by removing the adhesive backing, the phenomenon of the key assembly 2 being irreversibly attached after being tilted is avoided. A positioning assembly is provided on the front housing 1, and an adapter is provided on the key silicone rubber 21. The adapter and positioning assemblies are positioned and connected, allowing the key assembly 2 to be adjusted and accurately positioned during assembly. This facilitates installation of the key assembly 2 while also ensuring a consistent appearance gap between the key assembly 2 and the front housing 1 after assembly.

[0033] Specifically, the front shell 1 and the back shell 5 are both made of hard plastic material. The positioning component uses a positioning column 12, and the adapter component uses a positioning hole 23, and the positioning column 12 is inserted into the positioning hole 23. There are multiple positioning holes 23, and the key silicone 21 includes a mounting body 211, a key hole 212 is provided on the mounting body 211, a reset key drag 213 is provided on the key hole 212, and a key cap 22 is provided on the reset key drag 213. The mounting body 211 is a square structure, and positioning holes 23 are provided at least at the corners of the mounting body 211. The positioning columns 12 and the positioning holes 23 are the same in number and are arranged correspondingly. At this time, the mounting body 211 can achieve precise positioning and installation with the front shell 1. In this embodiment, the key assembly 2 is directly positioned and fixed on the front shell 1 through the connection between the positioning column 12 and the positioning hole 23, eliminating the need for adhesive bonding and fixing, and avoiding the phenomenon that the key assembly 2 is irreversible after being attached as a whole.

[0034] As a variable embodiment, the positions of the positioning post 12 and the positioning hole 23 can be interchanged, that is, the positioning component adopts the positioning hole 23 , the adapter component adopts the positioning post 12 , and the positioning post 12 is inserted into the positioning hole 23 .

[0035] Furthermore, a plurality of clearance holes 11 are arranged in a matrix, and the front shell 1 is provided with support ribs 13, which separate the plurality of clearance holes 11 into a matrix arrangement. The width of the support ribs 13 provided between adjacent clearance holes 11 is D1, and the width D1 of the support ribs 13 is less than 1.2 mm.

[0036] Specifically, in the prior art, due to the adhesive backing, the effective fitting size of the adhesive width must be ensured to be greater than 1.2mm, otherwise it is easy to cause debonding. At this time, the key spacing is too large, which easily affects the expansion requirements of the product appearance to be exquisite and fine. In this application, by removing the adhesive backing, the width D1 of the support rib 13 provided between adjacent clearance holes 11 can be made less than 1.2mm, and the minimum can be 0.5mm, which can greatly reduce the key spacing and allow the keyboard to be expanded to be more exquisite and fine. The key silica gel 21 includes a mounting body 211, a key hole 212 is provided on the mounting body 211, a reset key drag 213 is provided on the key hole 212, a key cap 22 is provided on the reset key drag 213, and the support rib 13 abuts the mounting body 211. The reset key drag 213 is made of elastic material. The distance L1 between the support rib 13 and the reset button 213 is 1. Because the width D1 of the support rib 13 between adjacent clearance holes 11 is less than 1.2 mm, the distance L1 between the support rib 13 and the reset button 213 can be made larger, ensuring that the reset button 213 is not easily deformed and scratched against the side wall of the clearance hole 11 of the front shell 1, thereby affecting the key pressing feel.

[0037] Furthermore, a touch portion is provided at the bottom of the reset button 213 , and the touch portion can abut against the display screen assembly 4 .

[0038] Specifically, the key cap 22 is set in the key hole 212 through the reset key tray. When the key cap 22 sinks due to external pressure, the key cap 22 transfers the pressure to the reset key tray, and the reset key tray is deformed and sinks synchronously. At this time, the touch portion set at the bottom of the reset key tray is driven by the reset key tray to sink, contact the display screen assembly 4 below, and transfer the pressure to the display screen assembly 4. The display screen assembly 4 controls the display screen assembly 4 to display relevant information within the range through the algorithm preset in the circuit board assembly 3. The relevant information displayed can be one or more, which enhances the user experience. Among them, the key cap 22 is fully transparent or translucent. The present invention is preferably fully transparent. The transparent property of the key cap 22 allows the user to clearly observe the content displayed on the display screen assembly 4 below when pressing the key cap 22, which is convenient for the user to identify. The material of the key cap 22 includes but is not limited to ABS, PC, glass, acrylic and other materials.

[0039] Furthermore, an exhaust groove 214 is provided at the bottom of the mounting body 211, and the exhaust groove 214 is connected to the key hole 212. By providing the exhaust groove 214 at the bottom of the mounting body 211, when the key cap 22 is pressed, the gas generated is discharged out of the mounting body 211 through the exhaust groove 214, thereby preventing the key cap 22 from being unable to return to its original position due to air pressure and being adsorbed on the mounting body 211 when the key cap 22 is released.

[0040] Specifically, a plurality of longitudinal exhaust grooves 214 and a plurality of transverse exhaust grooves 214 are provided at the bottom of the mounting body 211, and the longitudinal exhaust grooves 214 and the transverse exhaust grooves 214 respectively pass through the key hole 212. Through the longitudinal exhaust grooves 214 and the transverse exhaust grooves 214, when the key cap 22 is pressed, the gas generated is discharged to the outside of the mounting body 211 through the longitudinal exhaust grooves 214 and the transverse exhaust grooves 214, so as to avoid the key cap 22 being unable to rise due to air pressure when it rises and being adsorbed on the mounting body 211. In order to facilitate the installation of the circuit board assembly 3 on the display screen assembly 4, a positioning hanger 32 is provided on the circuit board assembly 3, and a connecting member 41 is provided on the display screen assembly 4, and the positioning hanger 32 is adapted to the connecting member 41. In this embodiment, as Figure 2 As shown, the positioning hanger 32 is a hook, and the connecting member 41 is a hanging groove. After the hook is hung on the display assembly 4, it is inserted into the hanging groove, thereby achieving a fixed connection between the circuit board assembly 3 and the display assembly 4. In order to prevent interference with the hook, a clearance groove is provided on the bottom shell to cooperate with the hook.

[0041] As a variable embodiment, the circuit board assembly 3 and the display screen assembly 4 may also be connected by magnetic fixation or snap fixation, which is not specifically limited here.

[0042] In this embodiment, the front shell 1 and the back shell 5 are both made of hard plastic material. The back shell 5 is snap-fitted to the front shell 1 and a accommodating chamber 6 is formed between the two. The snap-fitting method can be a snap-fit connection or an interference fit plug-in fixation. The key assembly 2, the circuit board assembly 3 and the display assembly 4 are all located in the accommodating chamber 6. A number of clearance holes 11 adapted to the key caps 22 are provided on the front shell 1, and the key caps 22 are exposed outside the front shell 1 through the clearance holes 11. Compared with the prior art, the technical solution of this embodiment removes the back glue, and a positioning column 12 is provided on the front shell 1, and a positioning hole 23 is provided on the key silicone 21, so as to avoid the phenomenon that the key assembly 2 is irreversibly attached after being offset. The positioning connection method of the positioning column 12 and the positioning hole 23 allows the key assembly 2 to be adjusted and accurately positioned during the assembly process, which facilitates the installation of the key assembly 2 while also ensuring the consistency of the appearance gap between the key assembly 2 and the front shell 1 after assembly.

[0043] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
