Referring to FIG. 2, the release mechanism 112 includes a sliding member 116, a linkage assembly 118 and a return member 146, and a release mechanism 112 coupled to the locking mechanism 102. The release mechanism 112 and the input unit 106 are both disposed on the first slide rail 110. The locking mechanism 102, the release mechanism 112, and the input unit 106 (the input unit 106 is illustrated in FIG. 1) slides inside and outside the frame 172 as the first slide rail 110 slides.

The second elastic member 152 connects the first slide rail 110 and the linkage assembly 118 to provide an elastic restoring force of the linkage assembly 118. The third elastic member 166 connects the first slide rail 110 and the sliding member 116 to provide a resilient restoring force of the sliding member 116.

The locking mechanism 102 includes a rotatable lever or cam for being driven to be in a first locked state (as shown in Figure 2), in a second locked state (as shown in Figure 7) or in a released state (e.g. Figure 4). The first locked state of the lock mechanism 102 is the tilted state as shown in FIG. The second locked state of the locking mechanism 102 is as shown in Fig. 8, which will be described later in detail. The release state of the lock mechanism 102 is as shown in Fig. 4, which will be described in detail later.

As shown in FIG. 2, the sliding member 116 is movably disposed on the first sliding rail 110, connected to the locking mechanism 102, and has a first sliding slot 120 and a second sliding slot 122 connected thereto. The first chute 120 is substantially perpendicular to one of the sliding directions D1 of the first rail 110 (extending along the z direction) and the second chute 122 is substantially parallel to the sliding direction D1 (extending along the x direction). The first chute 120 and the second chute 122 form an L-shaped chute. The first chute 120 is defined as a first locking position P1 at one end 134 in the z direction, and the second chute 122 is defined as a first locking position P1. The right slot end 170 of the x direction (shown in FIG. 7) is defined as a second locking position P2, and the junction of the first chute 120 and the second chute 122 (the turning point of the L-shaped chute) is defined. For a release position P3.

Referring to FIG. 2, the linkage assembly 118 is, for example, a linkage mechanism including a first link 160, a second link 162, and a first slider 124. The first slider 124 is disposed on the second link 162 and slidable between the first locking position P1, the release position P3 and the second locking position P2 of the first sliding slot 120 and the second sliding slot 122. The second link 162 is pivotally connected to the first link 160. The first link 160 is movably disposed on the first slide rail 110 and is driven by the pushing member 114 to drive the second link 162. The second connecting rod 162 is connected to the third sliding slot 164 of the first sliding rail 110 through the second sliding rod 168 , so that the linkage assembly 118 is movably disposed on the first sliding rail 110 . When the display 108 and the input unit 106 are in an open state, the open state is as shown in FIG. 2, in which the first slider 124 is located at one end 134 of the first chute 120 (ie, the first locked position P1). .

As shown in FIG. 2, in the first locking state of the locking mechanism 102, the first slider 124 of the linkage assembly 118 is located at one of the first locking positions P1 of the sliding member 116, and the locking mechanism 102 is limited to the second sliding. Between the first stop portion 140 and the second stop portion 142 of the rail 138, the first slide rail 110 cannot slide relative to the second slide rail 138. In this way, the display unit and the input unit module 100 are not slidably fixed to an operation position outside the frame 172 in the position of FIG. 2, so that the operator can stably open and close the input unit 106 and the display 108. .

Although the linkage assembly 118 of the present embodiment is exemplified by a linkage mechanism, it should be apparent to those skilled in the art that the linkage assembly 118 can be other mechanisms, such as a cam mechanism, a gear mechanism, or other configurations ( Configuration), etc.

With the sliding mechanism 104 described above, when the display 108 is covered by the input unit 106, the pushing element 114 is triggered by the pressing of the display 108, thereby driving the linkage assembly 118 and the sliding member 116 of the release mechanism 112 to slide the sliding member 116. Between a locked position P1, a second locked position P2 and a released position P3, the locking mechanism 102 is thus driven to be in the first locked state, the second locked state or the released state. The following is further explained.

Please refer to FIG. 3A and FIG. 3B at the same time, FIG. 3A is a schematic view showing the pushing element viewed in the direction V3 (-z direction) in FIG. 2, and FIG. 3B is a view showing the direction V2 in the third drawing. A perspective view of the pushing element. As shown in FIG. 3A, the first slide rail 110 has an opening 126. The first elastic member 128 of the sliding mechanism 104 connects the pushing member 114 and the first sliding rail 110, so that the pushing member 114 is movably disposed in the opening 126. . The pushing element 114 has a first inclined surface 130 (for compression triggering by the display 108) and a second inclined surface 132 (for driving the interlocking assembly 118).

As shown in FIG. 3B, during the process of the display 108 being covered by the input unit 106, the display 108 pushes the first inclined surface 130 in the closing direction D3 (-z direction), thereby driving the pushing member 114 to the pushing direction D4 (+y direction). The sliding causes the second inclined surface 132 to push the first link 160 of the linkage assembly 118 (the linkage assembly 118 and the first link 160 are shown in FIG. 3A) to move in the sliding direction D1. When the interlocking assembly 118 moves in the sliding direction D1 (+x direction), the locking mechanism 102 can be brought into a released state.

As shown in Fig. 4, it is a schematic view showing the locking mechanism of Fig. 2 in a released state. When the linkage assembly 118 moves in the sliding direction D1 (+x direction), the first slider 124 of the linkage assembly 118 slides from the one end 134 of the first sliding slot 120 (the first locking position P1) to the first sliding slot 120. A junction 136 (release position P3) is connected to one of the second chutes 122, and the second slider 168 is slid to the other end of the third chute 164. During the pushing of the interlocking assembly 118 by the pushing member 114, the first slider 124 of the linking assembly 118 slides from the first locking position P1 shown in FIG. 2 to the releasing position P3 shown in FIG. 4, thereby driving the sliding. Element 116. The sliding member 116 is simultaneously driven by the interlocking member 118 to slide in the slide-out direction D1 (+x direction).

During the sliding of the first slider 124 of the interlocking assembly 118 from the first locking position P1 to the releasing position P3, the sliding member 116 drives the locking mechanism 102 to change from the locked state shown in FIG. 2 to the fourth embodiment. Release status. The release state of the lock mechanism 102 is the horizontal state shown in FIG. In this released state, the locking mechanism 102 is no longer blocked by the first stop portion 140 and the second stop portion 142, so the first slide rail 110 can slide relative to the second slide rail 138. Thereby, the first slide rail 110 can be slid in the opposite direction of the slide-out direction D1 (+x direction), so that the display and the input unit module 100 can be returned to the inside of the rack 172 and stored.

Further, as shown in FIG. 4, when the first slider 124 of the interlocking assembly 118 is at the release position P3, although the elastic restoring force of the third elastic member 166 is intended to pull the sliding member 116 back to the first unlocking position P1. However, the second protrusion 150 of the restoring element 146 stops the first protrusion 144 of the sliding element 116, so that the sliding element 116 can be prevented from being driven by the third elastic element 166 in the opposite direction of the sliding direction D1 (+x direction). The lock mechanism 102 is held in the released state shown in FIG.

The following is a further description of the detailed structure of the return member 146, the process of sliding the first slider 124 of the interlocking assembly 118 from the first locked position P1 of FIG. 2 to the release position P3 of FIG. 4, and the sliding process of the sliding member 116. The relative positional relationship of the return member 146 and the first protrusion 144 of the sliding member 116.

Please refer to FIG. 5 and FIG. 6 simultaneously. FIG. 5 is an enlarged perspective view of a portion A in FIG. 2, and FIG. 6 is an enlarged perspective view showing a portion B in FIG. 4. As shown in FIG. 5, the returning member 146 is fixed to the first sliding rail 110 and includes an elastic cantilever 148, a third protruding portion 156 and the second protruding portion 150. The second projection 150 is coupled to one of the free ends 154 of the resilient cantilever 148. The third projection 156 is disposed between the free end 154 and one of the fixed ends 158 of the resilient cantilever 148.

During the sliding of the first slider 124 of the linkage assembly 118 from the first locked position P1 of FIG. 2 to the release position P3 of FIG. 4, the sliding member 116 will be driven in the +x direction, causing the sliding member 116 to be moved. The first protrusion 144 pushes the second protrusion 150 of the return member 146. Then, the elastic cantilever 148 is warped and deformed by being pushed by the first protruding portion 144 of the sliding member 116 until the first protruding portion 144 passes through the second protruding portion 150 due to the sliding of the sliding member 116 in the +x direction. As shown in Figures 4 and 6, the elastic cantilever 148 springs back to the free state as shown in Figures 5 and 6. In the state of Fig. 6, the second projecting portion 150 can stop the first projecting portion 144, and prevent the sliding member 116 from sliding in the sliding direction D2 (-x direction) by the pulling force of the third elastic member 166.

When the locking mechanism 102 is in the released state, the first sliding rail 110 can be in the opposite direction of the sliding direction D1 (+x direction), that is, the sliding direction D2 (-x direction) (the sliding direction D2 is shown in FIG. 7). Sliding to return the display and input unit module 100 to the interior of the frame 172 in a stowed position.

Further, please refer to FIG. 7 , which illustrates a schematic diagram of the returning element of FIG. 5 being lifted by the first stopping portion. A third projection 156 of the resilient cantilever 148 is disposed between the free end 154 of the resilient cantilever 148 and one of the fixed ends 158 of the resilient cantilever 148. During the sliding of the first sliding rail 110 relative to the second sliding rail 138 in the sliding direction D2 (−x direction), the third protruding portion 156 is pushed by the first stopping portion 140 of the second sliding rail 138. While the elastic cantilever 148 is warped, as shown in Fig. 7, the interference between the second projection 150 of the restoring member 146 and the first projection 144 of the sliding member 116 is thereby released.

After the interference between the second protrusion 150 of the return member 146 and the first protrusion 144 of the sliding member 116 is released, the second protrusion 150 of the return member 146 no longer stops the first protrusion of the sliding member 116. The portion 144 causes the elastic restoring force of the third elastic member 166 to slide the sliding member 116 in the -x direction, thereby sliding the first slider 124 of the linkage assembly 118 from the release position P3 to the second locking position P2 to drive The locking mechanism 102 is in the second locked state, as shown in Fig. 7. The relationship between the returning element 146 and the sliding element 116 is restored from the state of FIG. 6 to the state of FIG.

The display and input unit module 100 of Fig. 7 are in a storage position. That is, when the user does not use the display and the input unit module 100, the display 108 shown in FIG. 2 can be attached to the input unit 106 (the input unit 106 is shown in FIG. 1), and then slides in the direction. D2 (-x direction) pushes the positions of the first rails 110 to 7 to save space.

When the user wants to use the display and the input unit module 100, the first slide rail 110 can be pulled out in the sliding direction D1 (+x direction), so that the display and the input unit module 100 are operated as shown in FIG. status. Please refer to FIG. 8 , which is a schematic diagram of the first slide rail of FIG. 7 pulled out in the sliding direction D1. When the first slide rail 110 is pulled out from the position shown in FIG. 7 to the slide-out direction D1 (+x direction) to the position shown in FIG. 8, the lock mechanism 102 passes through the first stopper portion 140, Until being restrained between the first stop portion 140 and the second stop portion 142 of the second slide rail 138 to assume the first locked state. The matching design between the locking mechanism 102, the first stopping portion 140 and the second stopping portion 142 can make the locking mechanism 102 pass the first stopping portion 140 and the first state when changing from the seventh figure to the eighth state. The two stopping portions 142 are then engaged between the first stopping portion 140 and the second stopping portion 142.

If the display 108 shown in FIG. 8 is turned over on the input unit 106, the pushing member 114 is no longer blocked by the display 108 and is blocked by the first elastic member 128 (the first elastic member 128 is shown in FIG. 3B). The push direction D4 (-y direction) of Fig. 3B is pushed in the opposite direction. At the same time, since the interlocking assembly 118 is not blocked by the second inclined surface 132 of the pushing member 114, the elastic returning force of the first slider 124 of the interlocking assembly 118 by the second elastic member 152 is from the position shown in FIG. Pulling back causes the first slider 124 of the linkage assembly 118 to move from the second unlocking position P2 to the first locking position P1, as shown in FIG.

The release mechanism, the sliding mechanism and the display and the input unit module disclosed in the above embodiments of the present invention drive the pushing component through the display to drive the linkage component and the sliding component to change the sliding component from the locked position to the release position. The locking mechanism is brought to the released state by the locked state. In this way, the user can push the display and the input unit module to the storage position by sliding the display to the input unit with one hand, without consuming the time for searching for the mark, and no need to use any two hands to pull any mechanism.

In conclusion, the present invention has been disclosed in the above preferred embodiments, and is not intended to limit the present invention. A person skilled in the art can make various changes and modifications without departing from the spirit and scope of the invention. Therefore, the scope of the invention is defined by the scope of the appended claims.
