When the angle between the touch tablet 10 and the connector 11 exceeds 90 degrees, the activation plate 1051 of the activation part 105 of the touch tablet 10 presses against the driving plate 11231 of the driving part 1123 of the interlocking structure 112 of the connector 11. Meanwhile, the activation plate 1051 drives the driving plate 11231 to move towards a first direction I, as shown in FIG. 7B. The driving plate 11231 drives the first linkage 1121 to move towards the first direction I. The first linkage 1121 drives the second pivot end 1122a of the second linkage 1122 to move towards the first direction I. The second linkage 1122 rotates with respect to the first linkage 1121. The third pivot end 1122b of the second linkage 1122 drives the latch body 1131 of the latch 113 to move in a second direction II perpendicular to the first direction I, so that the positioning hook 133 of the positioning member 13 disposed at the keyboard dock 12 can detach from the latch body 1131 of the latch 113. At the same time, the positioning hook 133 comes off from the hole 11163 of the carrying part 1116 of the connector 11 and from the positioning part 1133 of the latch 113 for separating the connector 11 from the positioning member 13 at the keyboard dock 12. Consequently, the touch tablet 10 is detached from the keyboard dock 12, as shown in FIG. 7C.
Furthermore, the connector 11 can rotate an angle with respect to the touch tablet 10. The angle is the angle between the second surface 102 of the touch tablet 10 and the second surface 1112 of the connecting body 111. When the touch tablet 10 is disposed on a plane 3, the connector 11 can support the touch tablet 10 to be placed on the plane 3. The user can adjust the angle between the connector 11 and touch tablet 10 for adjusting the angle for touch controlling and viewing the touch tablet 10, as shown in FIG. 7D.
Please refer to FIG. 8, which shows a three-dimensional view of the connector according to the second embodiment of the present disclosure. As shown in the figure, in order to make the first linkage 1121 of the interlocking structure 112 drive the second pivot end 1122a of the second linkage 1122 to move towards the first direction I, a first limiting structure 117 is further disposed on the second surface 1112 of the connecting body 111. The extension direction of the first limiting structure 117 is parallel with the first direction I. The first pivot end 1121b of the first linkage 1121 pivoted at the interlocking structure 112 and the first pivot member 115 of the second pivot end 1122a of the second linkage 1122 are disposed at the first limiting structure 117. When the first linkage 1121 drives the second pivot end 1122a of the second linkage 1122 to move towards the first directions I, the first pivot member 115 moves on the first limiting structure 117, which confines the second pivot end 1122a of the second linkage 1122 to move in the first direction I.
In addition, a second limiting structure 118 is further disposed on the second surface 1112 of the connecting body 111. The extension direction of the second limiting structure 118 is parallel with the second direction II. The third pivot end 1122b pivoted at the second linkage 1122 and the second pivot member 116 of the pivot plate 1132 of the latch 113 are disposed at the second limiting structure 118. When the first linkage 1121 drives the second pivot end 1122a of the second linkage 1122 to move towards the first directions I, the second linkage 1122 rotates with respect to the first linkage 1121. At this time, the second pivot member 116 moves on the second limiting structure 118, which confines the third pivot end 1122b of the second linkage 1122 to move in the first direction I. Thereby, the third pivot end 1122b of the second linkage 1122 drives the latch 113 to move in the second direction II.
The first and second limiting structures 117, 118 according to the present embodiment comprises two projective bars, respectively. The two projective bars are arranged at intervals and parallel with each other. The extension direction of the two projective bars of the first limiting structure 117 is parallel with the first direction I; the extension direction of the two projective bars of the second limiting structure 118 is parallel with the second direction II. Besides, the first and second pivot members 115, 116 according to the present embodiment are projective pillars, respectively, disposed between the two limiting projective bars of the first limiting structure 117 and the two limiting projective bars of the second limiting structure 118, respectively. Alternatively, the first limiting structure 117, the second limiting structure 118, the first pivot member 115, and the second pivot member 116 can be other structures. The details will not be described further.
Moreover, at least a blocking part 114 is further disposed at the second end 1115 of the connecting body 111 of the connector 11. The blocking part 114 is located above the guiding groove 11162. The latch body 1131 of the latch 113 is located between the carrying part 1116 and the blocking part 114 for blocking the latch body 1131 of the latch 113 disposed in the guiding groove 11162, and thus preventing the latch body 1131 from coming off from the guiding groove 11162 and confining the latch body 1131 to move in the second direction II.
In addition, a recovery member 119 is further disposed between the second linkage 1122, or the latch 113, and the connecting body 111. The recovery member 119 includes a first end 1191 and a second end 1192. The first end 1191 of the recovery member 119 can be fixed to the pivot plate 1132 of the latch 113; the second end 1192 of the recovery member 119 is fixed on the second surface 1112 of the connecting body 111. When the third pivot end 1122b of the second linkage 1122 drives the latch 113 to move towards the second direction II, the recovery member 119 is stretched by the latch 119, generating a recovery force. When the second linkage 1122 stops driving the latch 113 to move towards the second direction II, the recovery force of the recovery member 119 drives the latch 113 to recover to the original position. The recovery member 119 according to the present disclosure is a spring. Alternatively, the recovery member 119 can be an elastic member or other devices having recovery force.
To sum up, the present disclosure provides a detachable touch notebook computer. According to the touch notebook computer of the present disclosure, the touch tablet is detached from the keyboard dock by rotating the touch tablet for driving the interlocking structure of the connector.
