As shown in Fig. 3B, the surface of the fixing member 124 is provided with three bumps 1244 and the above-mentioned bumps 1244 are on the center line of the fixing member 124 in the direction of the straight line B-B'. In this manner, the suspension member 122 can be swung to the left and right of the fixing member 124 along the center line of the straight line B-B' by the bumps 1244, that is, the user can press the touch unit 120 along the assembly direction of the touch unit 120. Since the two push switches 129 are located below the suspension 122, when the touch unit 120 is pressed, the corresponding push switch 129 can be triggered by the suspension 122. However, the present invention does not limit the position of the push switch 129. In addition, the two push switches 129 are equivalent to the left and right buttons around the touch area of the existing notebook computer. In other words, the movable touch module 12 provided in this embodiment combines the functions of the left and right buttons.

4A-4D are schematic diagrams showing the operation of a movable touch module according to a preferred embodiment of the present invention. Please refer to FIG. 2, FIG. 4A to FIG. 4D.

In this embodiment, as shown in FIG. 4A, the suspension member 122 is in an initial position (ie, the touch unit 120 is not activated). At this time, the receiving portion 1226 of the suspension member 122 does not contact the four-direction sensing element 126, and the rotation triggering portion 1228 does not contact any of the rotation sensing elements 128. The resilient portion 1224 of the suspension member 122 abuts against the stop wall 1004 of the housing 100 to maintain the suspension 122 in balance.

In this embodiment, when the user operates the touch unit 120 to move up and down or left and right along the bottom surface of the accommodating area 1000 of the housing 100 or rotate on the bottom surface of the accommodating area 1000, the touch unit 120 is fixed to the suspension unit. 122. Therefore, the suspension member 122 moves up and down and left and right with respect to the main body 10 along the plane of the fixing member 124 or rotates on the plane of the fixing member 124.

Specifically, when the user operates the touch unit 120 to move to the right along the bottom surface of the accommodating area 1000 of the housing 100, as shown in FIG. 4B, the suspension member 122 moves to the right along the plane of the fixing member 124. The left side wall of the receiving portion 1226 of the member 122 contacts and triggers the four-way sensing element 126 to the right, thereby controlling the electronic device to perform a corresponding function (eg, shifting the picture to the right or turning the page to the right). At this time, the elastic portion 1224 on the right side of the suspension member 122 is pressed against the stopper wall 1004 of the casing 100 on the right side thereof. Subsequently, when the user releases the touch unit 120, the elastic portion 1224 on the right side of the suspension member 122 pushes the suspension member 122 back to the initial position by its own resilience. Further, since the elastic portion 1224 on the left side of the suspension member 122 also has a certain elastic force, it is possible to ensure that the suspension member 122 does not deviate from the initial position due to being pushed by the right elastic portion 1224.

For example, in a practical application, when the display screen of the notebook computer is not large enough, the user can move the touch unit 120 to the right to control the screen display page to move to the right correspondingly. When the user releases the touch unit 120, the page stops moving, and the screen displays the corresponding portion of the page. In this way, the user only needs to move the touch unit 120 in different directions to conveniently browse the page.

In addition, in the embodiment, when the user operates the touch unit 120 to move to the left along the bottom surface of the accommodating area 1000 of the housing 100, the suspension member 122 moves to the left along the plane of the fixing member 124, and the suspension member The right side wall of the receiving portion 1226 of 122 contacts and triggers the four-way sensing element 126 to the left, thereby controlling the electronic device to perform a corresponding function (eg, shifting the picture to the left or turning the page to the left). At this time, the elastic portion 1224 on the left side of the suspension member 122 is pressed against the stopper wall 1004 of the casing 100 on the left side thereof. Subsequently, when the user releases the touch unit 120, the elastic portion 1224 on the left side of the suspension member 122 pushes the suspension member 122 back to the initial position by its own resilience.

In this embodiment, when the user operates the touch unit 120 to move upward along the bottom surface of the accommodating area 1000 of the housing 100, as shown in FIG. 4C, the suspension member 122 moves upward along the plane of the fixing member 124, and is suspended. The lower sidewall of the receiving portion 1226 of the member 122 contacts and upwardly triggers the four-way sensing element 126, thereby controlling the electronic device to perform a corresponding function (eg, moving up the picture or turning up the volume). At this time, the elastic portion 1224 on the upper side of the suspension member 122 is pressed against the stopper wall 1004 of the casing 100 on the upper side thereof. Subsequently, when the user releases the touch unit 120, the elastic portion 1224 on the upper side of the suspension member 122 pushes the suspension member 122 back to the initial position by its own resilience. Further, since the elastic portion 1224 on the lower side of the suspension member 122 also has a certain elastic force, it is possible to ensure that the suspension member 122 does not deviate from the initial position due to being pushed by the upper elastic portion 1224.

In addition, in the embodiment, when the user operates the touch unit 120 to move downward along the bottom surface of the accommodating area 1000 of the housing 100, the suspension member 122 moves downward along the plane of the fixing member 124, and the suspension member The upper side wall of the receiving portion 1226 of the 122 contacts and triggers the four-way sensing element 126 downward, thereby controlling the electronic device to perform a corresponding function (for example, moving down the picture or turning down the volume). At this time, the elastic portion 1224 on the lower side of the suspension member 122 is pressed against the stopper wall 1004 of the casing 100 on the lower side thereof. Subsequently, when the user releases the touch unit 120, the elastic portion 1224 on the lower side of the suspension member 122 pushes the suspension member 122 back to the initial position by its own resilience.

In this embodiment, when the user operates the touch unit 120 to rotate clockwise on the bottom surface of the accommodating area 1000 of the housing 100, as shown in FIG. 4D, the suspension member 122 is disposed on the plane of the fixing member 124. When the hour hand rotates, the rotation triggering portion 1228 on the left side of the suspension member 122 contacts and triggers the left rotation sensing element 128, thereby controlling the electronic device to perform a corresponding function (for example, rotating the picture clockwise or opening a program). At this time, the elastic portion 1224 on the four side walls of the suspension member 122 is pressed against the stopper wall 1004 of the casing 100 around it. Subsequently, when the user releases the touch unit 120, the elastic portion 1224 of the suspension member 122 simultaneously pushes the suspension member 122 back to the initial position by its own resilience. Further, since the elastic portions 1224 are provided on the four side walls of the suspension member 122, the suspension member 122 can be surely returned to the initial position.

In addition, in the embodiment, when the user operates the touch unit 120 to rotate counterclockwise on the bottom surface of the accommodating area 1000 of the housing 100, the suspension member 122 rotates counterclockwise on the plane of the fixing member 124. The rotation triggering portion 1228 on the right side of the member 122 contacts and triggers the right side of the rotation sensing element 128, thereby controlling the electronic device to perform a corresponding function (for example, rotating the picture counterclockwise or closing a program). At this time, the elastic portion 1224 on the four side walls of the suspension member 122 is pressed against the stopper wall 1004 of the casing 100 around it. Subsequently, when the user releases the touch unit 120, the elastic portion 1224 pushes the suspension member 122 back to the initial position by its own elastic force.

In addition, in the embodiment, since the four-direction sensing element 126 is a four-way lever type switch, the rotation sensing element 128 is also a lever type switch. Therefore, when the four-direction sensing element 126 or the rotation sensing element 128 is triggered, The four-way sensing element 126 or the rotational sensing element 128 can be automatically restored.

In addition, in the embodiment, the movable touch module 12 also has the function of left and right buttons. As shown in FIG. 3A, the user can press the touch unit 120 to trigger the push switch 129 that it covers. The touch unit 120 can be restored to the initial position by the elastic action of the push switch 129 itself.

In summary, the suspension of the movable touch module provided in this embodiment is movable relative to the main body on a plane. Moreover, the touch unit is fixed to the suspension. Thereby, the user can realize various functions by operating the touch unit to move the suspension along the plane or rotate on the plane to trigger the four-direction sensing element in different directions or trigger different rotation sensing elements. In addition, the movable touch module provided in this embodiment also incorporates a left and right button function. As such, the movable touch module provided by the embodiment and the electronic device using the same not only provide a novel and unique design but also provide a more convenient and efficient operation mode.
