DETAILED DESCRIPTION
Please refer to FIG. 1 and FIG. 2. FIG. 1 and FIG. 2 are exploded diagrams of a detachable combining device 10 in different views according to an embodiment of the present invention. The detachable combining device 10 includes a first casing 12 and a second casing 14. The first casing 12 includes two engaging portions 121. The first casing 12 and the second casing 14 are for covering an electronic module. For example, the first casing 12 and the second casing 14 of the detachable combining device 10 of the present invention can cover a panel module or a host module of the notebook computer for protection. The detachable combining device 10 further includes two buckling components 16 pivotably disposed on the second casing 14. As shown in FIG. 1 and FIG. 2, the buckling component 16 can be a T-shaped structure, and the T-shaped structure includes a supporting part and an engaging part. The buckling component 16 can pivot to the second casing 14 via the supporting part, and be fixed on the first casing 12 via the engaging part. Therefore, each buckling component 16 is for engaging with the corresponding engaging portion 121 of the first casing 12, so as to constrain a movement between the first casing 12 and the second casing 14.
In addition, the buckling component 16 can include an inclined structure 161 disposed on top of the engaging part. When the engaging portion 121 slides relative to the inclined structure 161, the buckling component 16 can pivot relative to the second casing 14 and be far away from the first casing 12 by the engaging portion 121, so as to prevent the first casing 12 and the second casing 14 from disassembly due to structural interference. The detachable combining device 10 further includes a latch 18 slidably disposed on the second casing 14. The latch 18 can include a main body 181, and two protrusions 183 disposed on two edges of the main body 181. The latch 18 can slide relative to the second casing 14 along a first direction D1 for driving the two protrusions 183 to pivot the buckling components 16 relative to the second casing 14, so as to separate the buckling component 16 from the engaging portion 121.
The detachable combining device 10 can further include two torsional springs 20 respectively disposed on the corresponding buckling component 16 and connected to the second casing 14. Each torsional spring 20 can provide a resilient recovering force for pivoting the buckling component 16 relative to the second casing 14, so as to engage the buckling component 16 with the engaging portion 121 of the first casing 12. The detachable combining device 10 can further include at least one resilient component 22, such as a stretching spring. The resilient component 22 can be disposed between the latch 18 and the second casing 14 for sliding the latch 18 relative to the second casing 14 along a direction opposite to the first direction D1, so as to recover the latch 18 to an initial position. The first casing 12 can include a guiding block 24, and the latch 18 can include a guiding structure 26 disposed on the middle of the main body 181. When the latch 18 slides relative to the second casing 14, the guiding structure 26 slides relative to the guiding block 24 for adjusting a distance between the first casing 12 and the second casing 14, such as pushing the first casing 12 away from the second casing 14 for separating the first casing 12 from the second casing 14. In addition, the latch 18 can include a pressing portion 28 disposed on the middle of the main body 181. The pressing portion 28 can be pushed or pulled for adjusting a position of the latch 18 relative to the second casing 14. Because the pressing portion 28 is disposed on the middle of the main body 181, the main body 181 can uniformly drive the two protrusions 183 to pivot the corresponding buckling component 16 relative to the second casing 14.
For increasing structural stability of an assembly of the first casing 12 and the second casing 14, as shown in FIG. 1 and FIG. 2, the first casing 14 can further include four first jointing structures 30, and the second casing 14 can include four second jointing structures 32. Generally, the first jointing structures 30 can be respectively disposed on four edges of the first casing 12. The second jointing structures 32 can be respectively disposed on four edges of the second casing 14, and position of each second jointing structure 32 can be designed according to the corresponding first jointing structure 30. In the embodiment of the present invention, the first jointing structure 30 can be a polygonal structure, such as an octagon structure. The second jointing structure 32 can be a circular structure, and the polygonal structure can be engaged inside the circular structure in a internally tangent manner. Each first jointing structure 30 can include a plurality of tenons 301 disposed on edges of adjacent lateral surfaces of the polygonal structure. An amount of the tenon 301 corresponds to a shape of the polygonal structure, and depends on design demand. The plurality of tenons 301 can be for engaging inside the corresponding sunken part 321 on the second jointing structure 32 when the first jointing structure 30 is combined with the second jointing structure 32. An assembly of the tenon 301 and the sunken part 321 can be applied for idle proof function. Further, when the first casing 12 is combined with the second casing 14, vibration and sound can be generated due to the assembly of the tenon 301 and the sunken part 321, so as to ensure correct operation of the detachable combining device 10.
It should be mentioned that the two engaging portions 121 of the first casing 12 can respectively be connected to the corresponding first jointing structure 30, and an engaging slot 323 can be further formed on the second jointing structure 32 at a position corresponding to the engaging portions 121 of the first jointing structure 30. When the first jointing structure 30 is engaged with the second jointing structure 32, the engaging portions 121 of the first casing 12 can be simultaneously engaged with the corresponding engaging slot 323 on the second jointing structure 32. The latch 18 can further include a constraining portion 34, and a constraining slot 141 can be formed on an inner surface of the second casing 14. Therefore, the latch 18 can slide on the second casing 14 via an assembly of the constraining portion 34 and the constraining slot 141, so as to correctly slide the latch 18 relative to the second casing 14 along the predetermined track.
