[0029] The utility model provides the following description with reference to the accompanying drawings to help fully understand the various embodiments of the utility model as defined by the claims and their equivalents. The description includes various specific details to help understanding, but these details should be regarded as exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the utility model.

[0030] In the description of the present invention, descriptions of orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0031] It will be understood that when one element (eg, a first element) is “connected” to another element (eg, a second element), the element may be directly connected to the other element or an intervening element (eg, a third element) may be present between the element and the other element.

[0032] The embodiment of the utility model provides a positioning plate of a keyboard, such as Figure 1-3 As shown, it includes a positioning plate body 100, which is provided with a plurality of positioning holes 110 penetrating the body, and the shaft body is used to pass through the positioning holes 110 to position the shaft body through the positioning holes 110. The bottom surface of the positioning plate body 100 is provided with a buckle 200 extending downward.

[0033] When installing the positioning plate of this embodiment, align the positioning plate body 100 with the PCB board, and then directly insert the positioning plate body 100 downward so that the snap-fit ​​parts 200 can be snap-fitted with the snap-fit ​​holes reserved on the PCB board to complete the installation of the positioning plate. The entire process does not require the use of screws, which saves the step of screwing, facilitates the quick installation of the positioning plate, reduces installation time, and improves production efficiency.

[0034] In some embodiments, the clip 200 includes two connecting rods 210 extending downward and two undercuts 220 respectively disposed at the lower ends of the two connecting rods 210. During the installation of the positioning plate, the connecting rods 210 and the undercuts 220 can be inserted into the clip holes on the PCB board. After the undercuts 220 pass through the clip holes, the undercuts 220 will be buckled on the bottom surface of the PCB board to limit the clip 200 from being disengaged from the clip holes upward, thereby installing the positioning plate body 100 in place.

[0035] Further, the two undercuts 220 can be arranged relative to each other, and the outer side surfaces 221 of the two undercuts 220 that are away from each other are all inclined. In the direction of downward extension, the outer side surfaces 221 of the two undercuts 220 that are away from each other gradually approach each other, so that the spacing between the lower ends of the outer side surfaces 221 of the two undercuts 220 is smaller than the spacing between the upper ends of the outer side surfaces 221 of the two undercuts 220. The lower end of the undercut 220 is easy to be inserted into the buckle hole of the PCB board, and the upper edge of the buckle hole will abut the outer side surfaces 221 of the two undercuts 220. As the undercut 220 goes deeper, the upper edge of the buckle hole gradually pushes the two undercuts 220, so that the connecting rod 210 undergoes a certain deformation, and the spacing between the two undercuts 220 is reduced, so that the connecting rod 210 can pass through the buckle hole; after the undercut 220 passes through the buckle hole, the connecting rod 210 is reset under the action of the deformation restoring force, and the spacing between the two undercuts 220 returns to the initial spacing, and the undercut 220 can be buckled on the bottom surface of the PCB board.

[0036] In some embodiments, positioning blocks 230 are provided on both sides of the fastener 200, the upper ends of the positioning blocks 230 are connected to the positioning plate body 100, and the lower ends extend downward. When installing the positioning plate, the two positioning blocks 230 can be inserted into the perforations reserved on the pad, so that the lateral movement of the positioning plate body 100 can be limited, and the positioning plate body 100 can be firmly installed in place.

[0037] Furthermore, the outer side surface of the positioning block 230 can be set to an arc structure, so that the positioning block 230 can be close to the inner wall of the perforation on the pad, which has a better limiting effect on the positioning plate body 100 and ensures that the positioning plate body 100 can be firmly installed in place.

[0038] In some embodiments, the positioning plate body 100 and the buckle 200 are integrally connected, which facilitates overall manufacturing and helps to enhance the connection strength between the positioning plate body 100 and the buckle 200. Specifically, the positioning plate body 100 and the buckle 200 can be made of plastic material, and the two can be integrally manufactured by injection molding.

[0039] Furthermore, the positioning plate body 100 is provided with avoidance holes 120 penetrating the positioning plate body 100 on both sides of the latch 200 , and the avoidance holes 120 allow inserts to pass through, so as to facilitate molding of the latch 200 by a mold, which can reduce the difficulty of molding.

[0040] The embodiment of the utility model provides a keyboard assembly, such as Figure 4-7 As shown, it includes a shaft body 300, a pad 400, a PCB board 500 and a positioning plate of a keyboard in any of the above embodiments. For the specific description of the positioning plate of the keyboard, reference can be made to the above embodiments. The shaft body 300 is inserted into the positioning hole 110. The positioning plate body 100, the pad 400 and the PCB board 500 are arranged sequentially from top to bottom. The pad 400 is used to provide a buffering protection for the PCB board 500. It can be made of soft materials such as silica gel. The PCB board 500 is provided with a corresponding circuit for connecting with the electrode sheet on the shaft body 300. The pad 400 is provided with a through hole 410 corresponding to the snap member 200 and penetrating itself, and the PCB board 500 is provided with a snap hole 510 adapted to the snap member 200. When assembling the whole, the pad 400 can be aligned with the PCB board first, and then inserted into the positioning plate body 100, and the buckle 200 will pass through the through hole 410 and engage with the buckle hole 510 to assemble the positioning plate body 100, the pad 400 and the PCB board 500 together. The whole process does not require the use of screws, which saves the step of screwing, facilitates the overall quick assembly, reduces the time required for assembly, and improves production efficiency.

[0041] In some embodiments, the clip 200 includes two connecting rods extending downward and two undercuts respectively disposed at the lower ends of the two connecting rods. During the assembly process, the connecting rods and the undercuts can be inserted into the clip holes 510 on the PCB board 500. After the undercuts pass through the clip holes 510, the undercuts will be buckled on the bottom surface of the PCB board 500 to restrict the clip 200 from being disengaged from the clip holes 510 upward, thereby completing the assembly.

[0042] Further, the two undercuts can be arranged relative to each other, and the outer sides of the two undercuts that are away from each other are inclined, and in the direction of downward extension, the outer sides of the two undercuts that are away from each other gradually approach each other, so that the spacing between the lower ends of the outer sides of the two undercuts is smaller than the spacing between the upper ends of the outer sides of the two undercuts. The lower end of the undercut is easy to be inserted into the buckle hole 510 of the PCB board 500, and the upper edge of the buckle hole 510 will abut the outer sides of the two undercuts. As the undercut goes deeper, the upper edge of the buckle hole 510 gradually pushes the two undercuts, so that the connecting rod undergoes a certain deformation, and the spacing between the two undercuts is reduced, so that the undercut can pass through the buckle hole 510; after the undercut passes through the buckle hole 510, the connecting rod is reset under the action of the deformation reset force, and the spacing between the two undercuts returns to the initial spacing, and the undercut can be buckled on the bottom surface of the PCB board 500.

[0043] In some embodiments, positioning blocks are provided on both sides of the clip 200, the upper ends of the positioning blocks are connected to the positioning plate body 100, and the lower ends extend downward. During assembly, the two positioning blocks are inserted into the through holes 410 reserved on the backing plate 400, so that the lateral movement of the positioning plate body 100 can be limited, and the positioning plate body 100 can be firmly installed in place.

[0044] Furthermore, the outer side surface of the positioning block can be set to an arc structure, so that the positioning block can be close to the inner wall of the through hole 410 on the pad 400, which has a better limiting effect on the positioning plate body 100 and ensures that the positioning plate body 100 can be firmly installed in place.

[0045] In some embodiments, a downwardly extending positioning column 310 is provided at the bottom of the shaft body 300, and the PCB board 500 is provided with a docking hole 520 adapted to the positioning column 310. The positioning column 310 passes through the pad 400 and is inserted into the docking hole 520, so that the shaking of the shaft body 300 can be limited, so that the shaft body 300 remains stable.

[0046] In some embodiments, the shaft body 300 is fixed in the positioning hole 110, and the shaft body 300 can remain stable. The shaft body 300 can be inserted into the positioning hole 110 first, and then the positioning plate body 100, the backing plate 400 and the PCB board 500 are assembled together. Specifically, the shaft body 300 can be fixed by interference fit, or a corresponding buckle structure can be provided on the shaft body 300 to buckle the shaft body 300 in the positioning hole 110 by using the buckle structure.

[0047] In some embodiments, a lamp bead 530 is fixed on the PCB board 500, and the shaft body 300 is provided with a light-transmitting hole 320 for light emitted by the lamp bead 530 to pass through. When the lamp bead 530 emits light, the light shines onto the keycap of the shaft body 300 through the light-transmitting hole 320 to light up the corresponding key.

[0048] In some embodiments, a receiving groove 420 may be provided on the top surface of the pad 400 , and a portion of the shaft 300 is embedded in the receiving groove 420 to prevent the bottom of the shaft 300 from directly abutting against the PCB board 500 .
