[0018] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0019] See also Figures 1 to 4 , the embodiments of the present utility model include:

[0020] A notebook keyboard module that is easy to disassemble, the notebook keyboard module includes a keyboard 1, a backlight panel 2, a positioning frame 3 and a base plate 4. The front of the positioning frame 3 is provided with a mounting groove, and the keyboard 1 and the backlight panel 2 are sequentially installed in the mounting groove from top to bottom. A plurality of positioning columns 5 are provided on the back of the positioning frame 3, and slide holes 6 are provided on the base plate 4 at positions corresponding to the positioning columns 5. The positioning frame 3 and the base plate 4 are detachably connected together through the positioning columns 5 and the slide holes 6.

[0021] The positioning column 5 includes a column cap 501 and a column body 502. The cross-sectional diameter of the column cap 501 is larger than the cross-sectional diameter of the column body 502. In actual design, it is generally 1.2 times the cross-sectional diameter of the column body 502. The height of the column body 502 is the same as the thickness of the base plate 4. The slide slot hole 6 includes a cap hole 601, a column hole 603 and a neck groove 602 connecting the cap hole 601 and the column hole 603. The inner diameter of the cap hole 601 is 1.1 times the outer diameter of the column cap 501. The inner diameter of the column hole 603 is matched with the outer diameter of the column body 502 with a positive tolerance. The notch of the connecting end of the neck groove 502 and the cap hole 601 is larger than the diameter of the column body 502. The notch of the connecting end of the neck groove 602 and the column hole 603 is smaller than the diameter of the column body 502, generally 0.8 to 0.95 times the diameter of the column 502. In actual production, the coefficient is generally selected as 0.85 times. Through this structure, during actual installation, it is only necessary to align one cap hole 601 with the column cap 501, and all the cap holes 601 will be aligned with the corresponding column cap 501. In this way, the whole is pressed down so that the column cap 501 just reaches the other side of the base plate 4, and then the entire positioning frame 3 is pushed to make the column 502 squeeze into the column hole 603 from the neck groove 602. Since the base plate 4 is made of plastic material and has a certain elasticity, the column 502 can be easily squeezed into the column hole 603 when pushed hard, and then the groove rebounds to clamp the column 502, and the column cap 501 clamps the base plate 4 from the other side of the base plate 4, and the base plate 4 and the positioning frame 3 are assembled together. When disassembling, you only need to apply force in the opposite direction to quickly complete the disassembly requirements.

[0022] The positioning frame 3 is provided with avoidance grids corresponding to the key positions of the keyboard 1, and the positioning posts 5 are all arranged at the intersections of the outer frames of the avoidance grids. The avoidance grids are provided because the backlight panel 2 is a soft board, and when the keyboard 1 is pressed, the backlight panel will be impacted. The avoidance grids can just avoid the direct impact of the pressing, preventing the circuit of the backlight panel 2 from being damaged by the force. The intersections of the outer frames of the avoidance grids are relatively strong, which can improve the stability of the positioning posts 5 after being subjected to force, and prevent the positioning posts 5 from being damaged during the pushing process.

[0023] The plurality of positioning posts 5 are divided into at least three groups, and are arranged in the left, right, and middle areas of the bottom of the positioning frame 3, respectively. Each group of positioning posts has no fewer than two posts, at least one of which is located near the top of the positioning frame 3 and at least one near the bottom of the positioning frame 3. In the present application, there are a total of six positioning posts, divided into three groups, each with two posts, one near the top of the positioning frame 3 and the other near the bottom of the positioning frame 3. This allows for the simultaneous action of multiple points to improve the stability of the base plate 4 and the positioning frame 3 after assembly.

[0024] In this application, the base plate 4 of the notebook keyboard module is connected to the positioning frame 3 in this way. On the one hand, when the base plate 4 and the positioning frame 3 are assembled together, the connection structure is stable and reliable. On the other hand, this connection structure is easy to disassemble and assemble without complicated disassembly actions. It is not only convenient for manual disassembly and assembly, but also convenient for matching with automated production lines. Using automated equipment to complete disassembly and assembly can significantly improve overall production efficiency.

[0025] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
