[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-7 As shown, this technical solution provides a multi-layered keyboard positioning plate, including a front panel 1 and a back panel 2. Through a unique structural design, it enables flexible applications: the front panel 1 can be used alone to adapt to membrane keys, and the front panel 1 and back panel 2 can be combined to adapt to mechanical keys. The front panel 1 and back panel 2 are detachably connected via a specific connection structure. A locking piece 3 is used to lock the back panel 2 onto the front panel 1 when the front panel 1 and back panel 2 are combined, ensuring the stability of the overall structure. Two embodiments are described below:

[0027] Example 1: Panel 1 uses adapter membrane buttons alone

[0028] When the keyboard positioning plate of the present invention needs to be applied to a membrane keyboard, only the panel 1 portion is needed. The panel 1 has a plurality of keycap holes 103, the number, position and size of which are designed according to the layout and specifications of the membrane keyboard to accurately fit the keycaps of the membrane keyboard.

[0029] During actual installation, the operator only needs to insert the membrane keycaps into the corresponding keycap holes 103 on panel 1. Since the keycap holes 103 match the size of the membrane keycaps, the keycaps are securely fixed in the holes 103, thus achieving accurate positioning of the membrane keys on the keyboard. This structure is simple and convenient, requiring no additional assembly steps, greatly improving the assembly efficiency of membrane keyboards.

[0030] Example 2: Panel 1 and base plate 2 are combined to use compatible mechanical buttons.

[0031] The panel 1 and the base plate 2 are connected by a detachable structure to meet different applications. For easy assembly, the bottom of the panel 1 has a pre-set groove 101, within which a positioning rod 102 is installed. The base plate 2 has positioning slots 204 that cooperate with the positioning rods 102; the number and position of the positioning slots 204 correspond to the positioning rods 102. During installation, the positioning slots 204 on the base plate 2 are aligned with the positioning rods 102 on the panel 1, allowing the positioning rods 102 to insert into the positioning slots 204, thus achieving initial positioning of the base plate 2 on the panel 1. This positioning method ensures accurate installation of the base plate 2 on the panel 1, avoiding installation deviations that could lead to difficulties in subsequent key installation or affect the normal use of the keyboard.

[0032] The bottom of panel 1 is provided with several rotatable locking plates 3, which are connected by a rotating shaft 4. After the base plate 2 is initially positioned, the operator rotates the locking plates 3, causing them to rotate along the axis of the rotating shaft 4 from the first recess 104 to above the groove 101, and further to the second recess 205 at the bottom of the base plate 2. At this time, the locking plates 3 firmly press the base plate 2 into the groove 101 of panel 1, achieving reliable locking of the base plate 2 on panel 1, ensuring the overall structural stability of the combined panel 1 and base plate 2, and enabling it to withstand the force generated by the mechanical buttons during pressing.

[0033] The base plate 2 has multiple first protrusions 201 that are interference-fitted with the keycap holes 103 of the panel 1. The number and position of the first protrusions 201 correspond to the keycap holes 103. A second protrusion 202 protruding upwards from the center of each first protrusion 201 is provided, and the second protrusion 202 has a shaft hole 203 that communicates with the bottom of the base plate 2. After the panel 1 and base plate 2 are assembled, the mechanical key's shaft is inserted into the shaft hole 203 of the second protrusion 202. Because the shaft hole 203 matches the size of the mechanical key's shaft, the shaft can be precisely supported and fixed within the shaft hole 203. Simultaneously, the outer side of the second protrusion 202 has an inclined surface 206 whose diameter gradually increases from top to bottom. This design helps improve the stability and firmness of the second protrusion 202, and when the key is pressed, the inclined surface 206 provides some support, improving the key's lifespan and pressing feel.

[0034] The panel 1 has several notches 105 and mounting screw holes 106 arranged circumferentially for positioning and installation. The notches 105 are distributed along the outer edge of the panel 1 and communicate with the outer surface of the panel 1. In practical applications, these notches 105 and mounting screw holes 106 can be used to position and install the entire keyboard positioning plate onto the keyboard housing or other supporting structures. For example, when installing the keyboard positioning plate onto the keyboard housing, the keyboard housing has positioning posts that match the notches 105 of the panel 1 and threaded holes that correspond to the mounting screw holes 106. By aligning the notches 105 of the panel 1 with the positioning posts of the keyboard housing, initial positioning is achieved. Then, screws are passed through the mounting screw holes 106 of the panel 1 and screwed into the threaded holes of the keyboard housing to securely install the keyboard positioning plate onto the keyboard housing, ensuring the stability and reliability of the overall keyboard structure.

[0035] Through the above embodiments, the multi-layered keyboard positioning plate provided by this technical solution enables flexible applications: panel 1 can be used alone to adapt to membrane keys, and panel 1 and base plate 2 can be used together to adapt to mechanical keys. In actual production and use, panel 1 alone or panel 1 combined with base plate 2 can be flexibly selected according to different product requirements, eliminating the need to develop multiple different positioning plates, greatly reducing production costs and management difficulty. At the same time, the keyboard positioning plate has a reasonable structural design, is easy to install, and provides accurate positioning, effectively improving keyboard assembly efficiency and product quality, and has good market application prospects.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
