7 to 9 are partial schematic views showing the operation of the electronic device inserted into the docking station, and FIG. 11 is a schematic view showing the second pushing portion 314c restricting the hook 318a. Referring to FIG. 6 , FIG. 7 and FIG. 11 simultaneously, in a state in which the electronic device 400 is not fully inserted into the docking station 300 and combined with the docking station 300 , the push top 316 a of the rotating member 316 protrudes from the first housing 312 . The top surface 312j, while the moving member 314 is in an unlocked position, and the second pushing portion 314c of the moving member 314 interferes with the hook 318a, and the hook 318a is restrained by the second pushing portion 314c, thus being in a lying state. .

Incidentally, in other embodiments not shown, in the case where the electronic device 400 is not fully inserted into the docking station 300 and coupled with the docking station 300 (the moving member 314 is in the unlocking position), the hook 318a may also be Upright, and the height of the hook 318a protruding from the top surface 312j of the first housing 312 in the first opening 312a may be higher than the height of the top surface 312j of the rotating member 316 protruding from the top surface 312j of the first housing 312 ( The push top 316a can only protrude slightly at the top surface 312j of the first housing 312, and the top surface of the hook 318a needs to be a slope, so before the electronic device 400 contacts the push top 316a of the rotating member 316. Upon contact with the hook 318a, the downward insertion of the electronic device 400 exerts a force to cause the hook 318a to be displaced to rotate downward from the upright state, so that the electronic device 400 can continue to move downward to engage the docking station 300.

10 is a schematic illustration of the shifting member 314 of the latching device translated to the right relative to the first housing 312. Referring to FIG. 4, FIG. 8 and FIG. 10 simultaneously, when the electronic device 400 continues to be inserted downward into the docking station 300, the electronic device 400 first contacts the push top 316a of the rotating member 316, and is received at the push top 316a. When the electronic device 400 is applied, the rotating member 316 rotates counterclockwise with its pivot shaft 316c as the axis, and the pushing top 316a gradually falls into the second opening 312b (ie, the top end of the pushing top 316a is lower than the first housing). The top surface 312j of 312 is shown in FIG. At this time, because of the rotation of the rotating member 316, the limit between the first limiting structure 316b of the rotating member 316 and a second limiting structure 314g of the moving member 314 is released, and the first limit of the embodiment is The structure 316b is a bump and the second limiting structure 314g is a groove, but is not limited thereto. Therefore, the limit of the first limiting structure 316b and the second limiting structure 314g After the position is released, the elastic restoring force of the elastic member 315 moves the moving member 314 to the right relative to the first portion 312c of the first housing 312 to a locked position. At this time, because the rail 314f is engaged with the pivot shaft 316c, the moving member The 314 is movable relative to the rotating member 316, and the limiting portion 314d contacts the first limiting structure 316b to limit the rotation of the rotating member 316. The moving distance of the moving member 314 can be determined by the length of the guide rail 314f or the distance of the limiting portion 314d against the pushing top 316a of the rotating member 316.

At the same time, the movement of the moving member 314 causes the second pushing portion 314c to release the hook 318a, and the torsion of the first torsion spring 318b causes the hook 318a to rotate in an upright state in a clockwise direction as shown in FIG. 12, and the hook 318a further The electronic device 400 is buckled, and the electronic device 400 is smoothly assembled on the docking station 300, as shown in FIG. Incidentally, at this time, the first guiding slope 314e of the first pushing portion 314b of the moving member 314 pushes the second guiding slope 319a of the button 319, and the button 319 protrudes from the button receiving hole 312g.

14 and 15 are schematic views of the movement of the button 319 in the button receiving hole 312g, and FIG. 16 is a schematic view of the moving member 314 of the latching device being translated to the left relative to the first housing 312. Referring to FIG. 14 , FIG. 15 and FIG. 16 simultaneously, when the electronic device 400 is removed from the docking station 300, the user can press the button 319, and the button receiving hole 312g limits the button 319 to the second pushing portion 314c. The normal direction N1 (shown in Figure 4) moves. The movement of the button 319 causes the second guiding slope 319a to move the first guiding slope 314e of the first pushing portion 314b of the moving member 314, and the moving member 314 is translated from the locked position to the left to an unlocked position. With the movement of the moving member 314, the second pushing portion 314c of the moving member 314 pushes the hook 318a, so that The hook 318a is pushed to a flat state (as shown in FIG. 18) in an upright state (as shown in FIG. 17), and the original rotating member 316 is rotated by the first limiting structure 316b being restricted by the bottom surface of the moving member 314. The member 316 cannot be rotated about its pivot axis 316c. At this time, the movement of the moving member 314 releases the restriction of the first limiting structure 316b (shown in FIG. 19), and the second torsion spring 317 is removed. The torque provided is such that the rotating member 316 rotates clockwise with its pivot axis as an axis, and the first limiting structure 316b (shown in FIG. 19) is engaged in the second limiting structure 314g (shown in FIG. 19) of the moving member 314. And pushing the top 316a to eject the electronic device 400 (as shown in FIG. 19), the user can conveniently and labor-savingly remove the electronic device 400 from the docking station 300 (as shown in FIG. 20).

Figure 21 is a schematic view of a latch device according to another embodiment of the present invention, and Figure 22 is a schematic view showing the use of the docking station of the latch device of Figure 21 to release the electronic device. Referring to FIG. 21 and FIG. 22 simultaneously, this embodiment is substantially the same as the above embodiment, except that the hooking portions 318c of the two hooks 318a of the present embodiment are disposed in opposite directions. The arrangement and connection relationship of the hook 318a and other components and the manner of operation are substantially the same as those of the above embodiment, and therefore will not be described herein. The two hooks 318a hook the electronic device 400 in opposite directions, and the two hooks 318a apply the opposite force to the electronic device 400, so that the connection between the electronic device 400 and the docking station can be further improved. Tight and not easy to separate.

In summary, the latching device of the embodiment of the present invention and the docking station using the latching device have the following advantages or differences from the conventional ones:

1. In contrast to allowing the user to apply a sliding force in a parallel direction to move the moving member in parallel, because the electronic device is assembled in the docking station, the electronic The whole of the device and the docking station is not easy for the user to hold by hand, so the force applied by the user has a component force in other directions, which causes the user to use a relatively large force to move in parallel. In contrast, in the present invention, when the button is engaged with the button accommodating hole, the user presses the button in the vertical direction, and there is no component force generated in other directions, so the user can drive the moving member to move with less force.

2. The moving member is provided with a first guiding inclined surface, and the first guiding inclined surface cooperates with the second guiding inclined surface disposed on the button, so the movement of the button after the force is transferred in the vertical direction is transferred to make the moving member parallel The movement of the direction causes the moving member to release the limit of the rotating member or to push the hook and rotate the hook to release the limit of the hook to the electronic device.

3. Pressing the push button to release the hook, and pushing the electronic component to the top of the electronic device ensures that the electronic device is removed from the docking station in the fully released state. In this way, it can be avoided that the electronic device and the docking station are damaged due to the incomplete removal of the electronic device by the hook and the strong removal of the electronic device from the docking station.

4. After the electronic device is inserted into the docking station, the rotating member rotates to release the limit of the moving member, and the elastic restoring force of the elastic member moves the moving member relative to the first housing and releases the limit of the hook, and the torsion spring drives The hook is rotated to the engaged state. This design allows the electronic device to be inserted into the docking station without the need for other manual forces or operations. The change in the angle of the rotating member will cause the pulling force of the hook bracket spring to be generated, thereby adjusting the hook to the engaged position.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention, and any one of ordinary skill in the art does not deviate. In the spirit and scope of the present invention, the scope of protection of the present invention is defined by the scope of the appended claims.
