[0002] The keyboards of notebook computers usually adopt fixed or detachable structural designs. In the detachable structural design, the keyboard is usually fixed by screws or a clamping structure is arranged around the keyboard (corresponding clamping structures are arranged around the keyboard and on the main body of the notebook computer). In the latter case, in order to firmly fix the keyboard to the main body of the notebook computer, screw fixation is usually supplemented. The aforementioned clamping structure is usually a fixed hook and a clamping groove, and the engagement between the two needs to be achieved through a slight elastic deformation of the structure. Repeated disassembly and assembly will inevitably cause structural damage to the hook or the clamping groove, affecting the bonding stability of the clamping structure. In addition, the aforementioned screw fixation requires tools and is quite time-consuming for disassembly and assembly. Summary of the Utility Model

[0037] To further understand the purpose, structure, features, and functions of the present utility model, the following is a detailed description in conjunction with the embodiments.

[0038] Please refer to Figure 1 and Figure 2 , Figure 1 is a schematic diagram of the keyboard module fixing structure according to the first embodiment; Figure 2 isFigure 1 Exploded schematic view of the fixing structure of the middle keyboard module. The fixing structure 1 of the keyboard module according to the first embodiment includes a keyboard module 12, a keyboard base 14, and a decorative cover 16. The keyboard module 12 is detachably connected to the keyboard base 14. The decorative cover 16 is also detachably connected to the keyboard base 14 and is disposed adjacent to the keyboard module 12. The keyboard module 12 includes a bottom plate 122, a plurality of keycaps 124 (alternatively marked in the figure), and a switch circuit board 126. The plurality of keycaps 124 are movably disposed on the bottom plate 122, for example, supported on the bottom plate 122 by other structures. The switch circuit board 126 is disposed between the bottom plate 122 and the plurality of keycaps 124. The keycap 124 can be pressed to move towards the bottom plate 122 to trigger the corresponding switch on the switch circuit board 126, for example, trigger the corresponding switch through an elastic round protrusion (directly disposed on the corresponding switch or all the elastic round protrusions are integrated into a single elastic structure layer). The keyboard module 12 further includes a circuit board tail 18, for example, but not limited to, formed by extending the switch circuit board 126. After the keyboard module 12 is installed on the keyboard base 14, the circuit board tail 18 can be inserted into the inside of the keyboard base 14 (through the opening 14a) and connected to the processing module 15 (represented by a dotted square) disposed inside the keyboard base 14. Thereby, the processing module 15 can receive the user input signal via the keyboard module 12 and can also selectively control the operation of the keyboard module 12. Figure 1 in the figure), whereby the processing module 15 can receive the user input signal via the keyboard module 12 and can also selectively control the operation of the keyboard module 12.

[0039] Please continue to refer to Figures 2 to 5 , Figure 3 is Figure 1 a schematic view of the keyboard module in another perspective in the figure; Figure 4 is Figure 2 an enlarged schematic view of circle A in the figure; Figure 5 is Figure 3 an enlarged schematic view of circle B in the figure. The bottom plate 122 of the keyboard module 12 has a first connection portion 1222. The keyboard base 14 has a second connection portion 142 corresponding to the first connection portion 1222. By detachably connecting the first connection portion 1222 and the second connection portion 142, the keyboard module 12 is detachably installed on the keyboard base 14. Among them, as Figure 2 and Figure 4 shown, the keyboard base 14 has a receiving groove 144 for receiving the keyboard module 12. The opening 14a is also located inside the receiving groove 144 for the circuit board tail 18 to pass through. The second connection portion 142 is located at the bottom of the receiving groove 144. As Figure 4As shown, the second connecting portion 142 is a through-hole structure, which has a large hole portion 142a and a small hole portion 142b. The large hole portion 142a and the small hole portion 142b are arranged in sequence in the first direction D1 (indicated by an arrow in the figure) and are in communication with each other. The large hole portion 142a serves as the opening of this through-hole, and the small hole portion 142b serves as the engaging portion of this through-hole. In the first embodiment, the contour of this through-hole is in a gourd shape, but it is not limited to this in practical applications. As Figure 3 and Figure 5 shown, the first connecting portion 1222 is a column with a hook portion 1222a. Generally speaking, the first connecting portion 1222 is a T-shaped column, and is fixedly arranged on the bottom plate 122 body by, for example but not limited to, riveting. As Figure 6 shown, Figure 6 is a cross-sectional schematic view of the engagement between the first connecting portion of the bottom plate of the keyboard module and the second connecting portion of the keyboard base, and the cross-sectional position thereof corresponds to Figure 4 the center line X-X. The first connecting portion 1222 and the second connecting portion 142 enter the engaging portion in the second direction D2 (indicated by an arrow in the figure) through the opening (i.e., the large hole portion 142a) via the column and the hook portion 1222a holds the engaging portion (i.e., the small hole portion 142b) to achieve engagement. Among them, the second direction D2 is opposite to the first direction D1.

[0040] In addition, in the first embodiment, as Figure 2 and Figure 3 , the bottom plate 122 further has a plurality of third connecting portions 1224 (one of which is marked in the figure), and the keyboard base 14 correspondingly has a plurality of fourth connecting portions 146 (one of which is marked in the figure). The third connecting portion 1224 has the same structure as the first connecting portion 1222, and the fourth connecting portion 146 has the same structure as the second connecting portion 142, so they will not be described in detail; but it is not limited to this in practical applications. Therefore, the keyboard module 12 is fixed to the keyboard base 14 by the first connecting portion 1222 and the plurality of third connecting portions 1224 correspondingly engaging with the second connecting portion 142 and the plurality of fourth connecting portions 146. In an embodiment, the number of the first connecting portion 1222 and the third connecting portion 1224 can be determined according to actual needs.

[0041] In addition, in this embodiment, as Figure 7 shown, Figure 7It is a bottom view schematic diagram of the keyboard module. The bottom plate 122 of the keyboard module 12 extends along the third direction D3 (indicated by an arrow in the figure) and is strip-shaped. Among them, the third direction D3 is perpendicular to the first direction D1 (or the second direction D2). The connecting parts on the bottom plate 122 (including the first connecting part 1222 and the plurality of third connecting parts 1224) are distributed in a non-uniform manner. When four areas that are roughly equal in area and connected are defined along the third direction D3 on the bottom plate 122, and the four areas are the first area 122a, the second area 122b, the third area 122c, and the fourth area 122d (separated by vertical chain lines), the number of connecting parts provided on the bottom plate 122 in the first area 122a is greater than the number provided in the second area 122b or the third area 122c, and the number of connecting parts provided on the bottom plate 122 in the fourth area 122d is also greater than the number provided in the second area 122b or the third area 122c. In other words, the number of connecting parts provided on the left and right sides of the bottom plate 122 (in terms of Figure 7 viewpoint) is greater than the number of connecting parts provided on the inner side of the bottom plate 122. This distribution of connecting parts helps to fix both sides of the keyboard module 12. Among them, the first area 122a is the area on the bottom plate 122 close to the outside along the third direction D3. Generally speaking, some long keys of the keyboard module 12 (such as the backward key, the input key, the shift key, and the capital key, etc.) are provided corresponding to the first area 122a and the fourth area 122d (can be compared simultaneously Figure 2 and Figure 7 ), so the aforementioned distribution of connecting parts helps the actuation stability of these long keys.

[0042] In addition, when three areas that are roughly equal in area and connected are defined along the first direction D1 on the bottom plate 122, and the three areas are the fifth area 122e, the sixth area 122f, and the seventh area 122g (separated by horizontal chain lines), the number of connecting parts provided on the bottom plate 122 in the seventh area 122g is greater than the number provided in the fifth area 122e or the sixth area 122f. In other words, the number of connecting parts provided on the upper side of the bottom plate 122 (or the side away from the tail 18 of the circuit board, when the keyboard module 12 is applied to a notebook computer, it is the side of the bottom plate 122 close to the display) is the largest. In other words, this distribution of connecting parts helps to fix the upper side of the keyboard module 12 (in terms of Figure 7 viewpoint). In the first embodiment, one side of the bottom plate 122 in the second direction D2 (or the side close to the processing module 15) has a plurality of first tongues 1226, and the keyboard base 14 correspondingly has a plurality of openings 14b inside the receiving groove 144 (refer to Figure 2)。After the keyboard module 12 is fixed to the keyboard base 14, the plurality of first tongue pieces 1226 are inserted (via the opening 14b) into the inner side of the keyboard base 14, which helps to fix the lower side of the keyboard module 12 on the keyboard base 14. In addition, in this embodiment, the first tongue piece 1226 has a through hole 1226a (alternatively marked in the figure). After the keyboard module 12 is fixed to the keyboard base 14, a screw can pass through the through hole 1226a to be locked into the keyboard base 14, thereby enhancing the fixing effect of the keyboard module 12. Additionally, in the first embodiment, as Figure 2 and Figure 3 shown, one side of the bottom plate 122 in the first direction D1 (when the keyboard module 12 is applied to a laptop computer, it is the side of the bottom plate 122 close to the display) has a plurality of second tongue pieces 1228, and the second tongue pieces 1228 have through holes 1228a. After the keyboard module 12 is fixed to the keyboard base 14, a screw can pass through the through hole 1228a to be locked into the keyboard base 14, which can also enhance the fixing effect of the keyboard module 12.

[0043] During the actual process of assembling the keyboard module 12 to the keyboard base 14, in principle, first align the columns on the bottom plate 122 (i.e., the first connecting portion 1222 and the third connecting portion 1224) with the large hole portions 142a of the corresponding through holes (i.e., the second connecting portion 142 and the fourth connecting portion 146) at the bottom of the receiving groove 144, and then engage the first connecting portion 1222 and the third connecting portion 1224 with the second connecting portion 142 and the fourth connecting portion 146. In the first embodiment, as Figure 2As shown, the keyboard base 14 has two positioning portions 148, which are respectively located at the bottom of the receiving slot 144. Further, in the third direction D3, the two positioning portions 148 can be respectively adjacent to both ends of the receiving slot 144. During the aforementioned installation process, the user can tilt the keyboard module 12 into the receiving slot 144, and then move the keyboard module 12 relative to the keyboard base 14 while maintaining the tilt in the first direction D1 until the structural edge 122h of the bottom plate 122 of the keyboard module 12 abuts against the positioning portion 148. Then, place the keyboard module 12 flat on the keyboard base 14 (or the bottom of the receiving slot 144) so that the columns (i.e., the first connecting portion 1222 and the third connecting portion 1224) on the bottom plate 122 are aligned with the large hole portions 142a (i.e., the openings of the through holes) of the corresponding through holes (i.e., the second connecting portion 142 and the fourth connecting portion 146) on the bottom of the receiving slot 144. Then, move the keyboard module 12 relative to the keyboard base 14 in the second direction D2 (i.e., opposite to the first direction D1) so that all the columns slide into the small hole portions 142b (i.e., the engaging portions of the through holes) of the corresponding through holes, thus completing the engagement of the first connecting portion 1222 and the third connecting portion 1224 with the second connecting portion 142 and the fourth connecting portion 146. At this time, the structural edge 122h leaves the positioning portion 148. In addition, during the movement in the second direction D2, the first tongue 1226 of the bottom plate 122 will also be inserted into the opening 14b; then the first tongue 1226 can be fixed to the inner side of the keyboard base 14 by using screws passing through the through hole 1226a, thereby enhancing the fixing effect of the keyboard module 12. In addition, before the aforementioned movement of the keyboard module 12 in the second direction D2, the tail portion 18 of the circuit board can be passed through the opening 14a to enter the inner side of the keyboard base 14, and after the aforementioned connection portions are engaged, the tail portion 18 of the circuit board is connected to the processing module 15 (see Figure 1 ).

[0044] In practical applications, when the keyboard module 12 is tilted into the receiving slot 144, both sides of the receiving slot 144 (in the third direction D3) also provide structural limits to the keyboard module 12. Therefore, after the structural edge 122h of the bottom plate 122 of the keyboard module 12 abuts against the positioning portion 148, when the keyboard module 12 is placed flat, all the columns can automatically align with the large hole portions 142a of the corresponding through holes. This structural design facilitates assembly. In addition, in the first embodiment, the positioning portion 148 is a protrusion (such as, but not limited to, a column), which is provided on the bottom of the receiving slot 144. In practical applications, the side wall of the receiving slot 144 can also be directly used as the positioning portion 148.

[0045] After the first connecting portion 1222 and the third connecting portion 1224 are engaged with the second connecting portion 142 and the fourth connecting portion 146, in principle, the keyboard module 12 is already fixed to the keyboard base 14. There is a gap between the upper side of the keyboard module 12 (i.e., one side in the first direction D1, corresponding to the structural edge 122h) and the side wall of the receiving groove 144. The decorative cover 16 is assembled to the keyboard base 14 to abut against the upper side of the keyboard module 12 and is received in the receiving groove 144, so that the decorative cover 16 and the keyboard module 12 jointly shield the receiving groove 144, enhancing the aesthetics.

[0046] In addition, in the first embodiment, the first connecting portion 1222 and the third connecting portion 1224 are made of columns, and the second connecting portion 142 and the fourth connecting portion 146 are made of through holes; however, this is not limited in actual applications. For example, the first connecting portion 1222 and the third connecting portion 1224 are made of through holes, and the second connecting portion 142 and the fourth connecting portion 146 are made of columns. In actual applications, the first connecting portion 1222 and the third connecting portion 1224 are not limited to the same structure; the same applies to the second connecting portion 142 and the fourth connecting portion 146.

[0047] As described above, in the operation of assembling the keyboard module 12 to the keyboard base 14, in addition to screwing the first tongue piece 1226 and the second tongue piece 1228, in principle, no hand tools are required, which increases the operation convenience and can effectively shorten the assembly time. In the disassembly and assembly operations of the keyboard module 12, the first connecting portion 1222, the second connecting portion 142, the third connecting portion 1224, and the fourth connecting portion 146 can all be not damaged. Therefore, the detachable connection structure formed by the first connecting portion 1222, the second connecting portion 142, the third connecting portion 1224, and the fourth connecting portion 146 is still stable and reliable. In addition, in actual applications, the keyboard module fixing structure 1 can be applied to independent keyboard products (such as external keyboards), or can also be applied to integrated keyboards (such as laptop keyboards).

[0048] In addition, in the first embodiment, the second connecting portion 142 is a simple through hole structure, but this is not limited in actual applications. For example, as Figure 8 shown, Figure 8 is a schematic diagram of a variation of the second connecting portion. The through hole 143 also has a large hole portion 143a and a small hole portion 143b, and the through hole 143 also has a counterbore structure 143c. The counterbore structure 143c can accommodate the hook portion 1222a (shown in dotted lines in the figure), reducing or avoiding the hook portion 1222a protruding from the bottom plate 122.

[0049] In addition, in the first embodiment, the first connecting portion 1222 and the second connecting portion 142 are made of a through-hole and a column with a hook portion, and the connection between the two is achieved by the hook portion being hooked on one side of the through-hole; on the other hand, the combination of the through-hole and the column with a hook portion can logically be regarded as a detachable connection structure between the keyboard module 12 and the keyboard base 14. However, this is not limited in actual applications. For example, please refer to Figure 9 and Figure 10 , Figure 9 which is a schematic diagram of the detachable connection structure according to the second embodiment; Figure 10 is Figure 9 an exploded schematic diagram of the detachable connection structure in Figure 9 . The detachable connection structure according to the second embodiment is used to replace the first connecting portion 1222 and the second connecting portion 142 and is applied to the base plate 122 and the keyboard base 14. The detachable connection structure of the second embodiment includes a through-hole 30, a hook 32, and a engaging member 34. The through-hole 30 is formed in the keyboard base 14, the hook 32 is fixedly arranged on the base plate 122, and the engaging member 34 is a movable member. During the assembly process, first, the hook 32 is passed through the through-hole 30, and then the engaging member 34 is snapped into the space between the hook 32 and the keyboard base 14 (as shown in

[0050] ). Figure 11 and Figure 12 , Figure 11 which is a schematic diagram of the detachable connection structure according to the third embodiment; Figure 12 is Figure 11 an exploded schematic diagram of the detachable connection structure in Figure 11 . The detachable connection structure according to the third embodiment is used to replace the first connecting portion 1222 and the second connecting portion 142 and is applied to the base plate 122 and the keyboard base 14. The detachable connection structure of the third embodiment includes a through-hole 40 and a hook 42. The through-hole 40 is formed in the keyboard base 14, and the hook 42 is fixedly arranged on the base plate 122. The through-hole 40 has an interference portion 402 that protrudes toward the center of the through-hole 40. During the assembly operation, it is achieved by directly snapping the hook 42 into the through-hole 40, as shown in Figure 11 . Among them, the hook 42 and / or the interference portion 402 has a certain elasticity. When the hook 42 enters the through-hole 40, the hook 42 will have a structural interference with the interference portion 402, and finally hook the interference portion 402. The end of the hook 42 may have a chamfer structure 422, and the chamfer structure 422 has a structural interference with the interference portion 402. As shown in Figure 12 , the length 422a of the chamfer structure 422 is greater than the length 402a of the interference portion 402, which can reduce the degree of structural interference during the assembly process and extend the service life of this detachable connection structure.

[0051] For another example, please refer to Figures 13 to 15 , Figure 13Schematic diagram of a detachable connection structure according to the fourth embodiment; Figure 14 is Figure 13 exploded schematic diagram of the detachable connection structure in; Figure 15 is Figure 13 schematic diagram of the retaining member installed with a tool in. The detachable connection structure according to the fourth embodiment is used to replace the first connection portion 1222 and the second connection portion 142 and is applied to the bottom plate 122 and the keyboard base 14. The detachable connection structure of the fourth embodiment includes a through hole 50, a column 52, and a retaining member 54. The through hole 50 is formed in the keyboard base 14, the column 52 is fixedly disposed on the bottom plate 122, and the retaining member 54 is a movable member. The retaining member 54 is integrally annular, and includes an annular body 542, a plurality of first abutting feet 544 protruding obliquely downward from the outer edge of the annular body 542, and second abutting feet 546 protruding obliquely upward from the inner edge of the annular body 542. During the assembly process, first, the column 52 is passed through the through hole 50, and then the retaining member 54 is sleeved on the column 52 so that the second abutting feet 546 tightly abut against the column 52; then, a tool 56 (such as a handheld tool having a groove 562) is used to sleeve the retaining member 54 and move the retaining member 54 downward (or towards the keyboard base 14) (as Figure 15 shown), until the retaining member 54 tightly abuts against the keyboard base 14, thereby completing the connection (as Figure 14 shown). After the connection, the retaining member 54 applies a force to the keyboard base 14 via the first abutting feet 544, and applies a force to the column 52 via the second abutting feet 546, so that the retaining member 54 assembles the bottom plate 122 and the keyboard base 14 together.

[0052] In summary, the keyboard module fixing structure of the present invention includes a keyboard module and a keyboard base. The keyboard module has a bottom plate, and the bottom plate has a first connection portion and a structural edge. The keyboard base has a second connection portion and a positioning portion, and the second connection portion corresponds to the first connection portion. Among them, during the process of fixing the keyboard module to the keyboard base, the keyboard module is tilted and moved relative to the keyboard base in a first direction until the structural edge abuts against the positioning portion. Then, the keyboard module is placed flat on the keyboard base to align the first connection portion with the second connection portion, and the keyboard module is then moved relative to the keyboard base in a second direction opposite to the first direction to engage the first connection portion with the second connection portion. Thereby, the keyboard module can engage the first connection portion with the second connection portion through a simple sliding operation, and is thus fixed to the keyboard base. The design of this sliding operation can effectively improve the disassembly and assembly efficiency of the keyboard module. In addition, in practical applications, this sliding operation can be performed without using tools, greatly reducing the disassembly and assembly time; and the engagement process of the first connection portion of the keyboard module and the second connection portion of the keyboard base does not involve structural deformation, and the combined stability of the first connection portion and the second connection portion can be maintained well, and the structural service life of the first connection portion and the second connection portion can be extended.
