The connection makes part of the linkage mechanism module 2 covered by the casing 3.

When the expansion base 1 is in a hook state, as shown in FIGS. 3 and 4, the electronic device is disposed on the first surface 31 (not shown), the switch 23 is located at a first position P1, and the switch 23 is protruding.于 第一 表面 31。 The first surface 31. The hook member 21 is located at a buckling position P2, that is, the hook member 21 extends from the first opening 321 and is hooked to the electronic device, and because the hook member 21 extends forward toward the first opening 321, The first elastic member 246 is not pressed, so an elastic restoring force of the first elastic member 246 at this time is the smallest. In addition, the second end portion 2412 of the driving member 241 presses the third end portion 2431 of the driven member 243 to maximize the distance between the fifth end portion 2211 of the swinging member 221 and the first hook portion 2453, thereby stretching When the second elastic member 247 and the second elastic member 247 are in the hook state, the second elastic restoring force generated is the largest, and the abutting member 22 is located in a sinking position P3, that is, the abutting unit 222 is located below the first surface 31 .

5 and 6 show that the expansion base 1 is in a lifted state, and when the expansion base 1 is to enter a ceiling state from the hook state (change from the state of FIG. 4 to the state of FIG. 6), the switch 23 is pressed by The first position P1 is moved to a second position P4, so that the switch 23 is located below the first surface 31, which drives the first shaft 242 to rotate, and then the first shaft 242 drives the driving member 241 to rotate until the second end of the driving member 241 The part 2412 is located in the recessed part 2433. The hook member 21 is driven by the driving member 241 to be located in a trip position P5 and hidden in the shielding portion 32. Therefore, the electronic device releases the hook relationship with the hook member 21, first The elastic member 246 is twisted due to the movement of the hook member 21 to generate a first elastic restoring force. The driven member 243 rotates without being pressed by the driving member 241, which drives the second shaft 244 to rotate, and the second shaft 244 drives the swinging member 221 to rotate. At this time, the second elastic member 247 provides a second elastic restoring force The abutting member 22 is moved from the sinking position P3 to the lifting position P6, that is, the abutting unit 222 extends from the second opening 311 and is located on the first surface 31, and resists the electronic device to be raised to a certain height, thereby expanding The seat 1 is completely in a raised state. In this state, the distance between the fifth end portion 2211 and the first hook portion 2453 is the smallest, and the force provided by the second elastic member 247 is also the smallest. The first elastic force is the largest, and in the raised state, the user must easily reach into the space between the electronic device and the first surface 31 to separate the electronic device from the expansion base 1.

When the expansion base 1 is to re-enter the hook state from the raised state (transitioned from the state of FIG. 6 to the state of FIG. 4), the switch 23 will be moved from the second position P4 to the first position P1. At this time, the first shaft 242 is rotated again, and the first elastic member 246 provides a first elastic restoring force to provide force to move the hook member 21 from the unlocking position P5 to the hook position, and the second end portion 2412 of the driving member 241 is re-set from the recessed portion 2433. Moved to the third end portion 2431 of the depressing follower 243, the follower 243 is thus rotated to drive the abutment member 22 from the lifting position P6 to the sinking position P3, and the fifth end portion 2211 is far from the first hook portion 2453, The second elastic member 247 is stretched again to generate the maximum second elastic restoring force, so as to provide a force for the abutting member 22 to enter the lifting state again.

It should be noted that when the first elastic member 246 is provided on the driving member 241 and one of the first platforms 248, and when the second elastic member 247 is provided between the fifth end portion 2211 and the first hook portion 2453, Both the first elastic member 246 and the second elastic member 247 are pre-twisted or pre-tensioned to a certain extent, so as to ensure that the first elastic member 246 and the second elastic member 247 will not be subjected to other untwisted or stretched ones. The component is loose. And again, before the expansion base 1 enters the hook state (in the raised state), the first elastic restoring force provided by the first elastic member 246 is the largest, so the first elastic member 246 will provide a force for the hook member 21 to The trip position P5 moves to the hook position. Before the expansion base 1 enters the lifted state (in the hook state), the second elastic member 247 provides the maximum elastic restoring force, so the second elastic member 247 will provide a force for the abutting member 22 to be lifted from the sinking position P3. Position P6.

In summary, the present invention can effectively simplify the assembly process of the linkage mechanism module after all the components of the linkage mechanism module are set on the fixed seat and then further combined with the housing 3. And through the abutment of the abutment member 22, the electronic device can be easily combined and separated from the expansion base, and the user is more convenient in operation.
