Detailed Description
In order to further understand the objects, structures, features and functions of the present invention, the following embodiments are described in detail.
Referring to fig. 1 to 4, fig. 1 is a perspective view of an electronic device 1 according to an embodiment of the invention, fig. 2 is a perspective view of a fixed member 122, a connecting member 124, a rotating member 126 and a torsion spring 128 in fig. 1, fig. 3 is a perspective view of the rotating member 126 in fig. 2 from another perspective, and fig. 4 is an exploded view of the fixed member 122, the connecting member 124, the rotating member 126 and the torsion spring 128 in fig. 2.
As shown in fig. 1, the electronic device 1 includes an electronic unit 10 and a supporting frame 12. The electronic unit 10 is disposed on the supporting frame 12, so that the electronic unit 10 is supported on the supporting frame 12 for a user to see. In practical applications, the electronic unit 10 may be a liquid crystal display, a plasma display, or other electronic devices that can be supported on the supporting frame 12. It should be noted that other objects can be disposed on the supporting frame 12 according to practical applications, and the electronic unit is not limited to be disposed.
As shown in fig. 2 to 4, the supporting frame 12 includes a frame body 120, a fixing member 122, a connecting member 124, a rotating member 126 and a torsion spring 128. The electronic unit 10 is disposed on the rotating member 126. The fixing member 122 is disposed on the frame body 120. In this embodiment, the frame 120 may include a hinge shaft 1200 and a base 1202. The fixing member 122 can be connected to the hinge shaft 1200, so that the electronic unit 10 can be turned up and down by the hinge shaft 1200.
The fixing element 122 includes a first hinge shaft 1220, and the connecting element 124 is pivotally connected to the first hinge shaft 1220. The connecting member 124 includes a first stopping portion 1240, a second stopping portion 1242, a third stopping portion 1244 and a second hinge shaft 1246. The connecting member 124 can rotate relative to the fixing member 122 via the first hinge shaft 1220, so that the first stopping portion 1240 or the second stopping portion 1242 abuts against the fixing member 122 to limit the rotation angle of the connecting member 124. As shown in fig. 1 and fig. 2, when the electronic unit 10 is in the landscape mode, the first stopping portion 1240 of the connecting member 124 abuts against the upper side edge of the fixing member 122. In addition, the two ends of the torsion spring 128 are respectively connected to the fixing member 122 and the connecting member 124. In this embodiment, the torsion spring 128 is disposed on the first hinge shaft 1220.
The rotating member 126 is pivotally connected to the second hinge shaft 1246 of the connecting member 124, and the rotating member 126 includes an arc-shaped slot 1260. As shown in fig. 2 and fig. 3, when the rotating member 126 is pivotally connected to the second pivot shaft 1246 of the connecting member 124, the third stopping portion 1244 of the connecting member 124 is located in the arc-shaped slot 1260 of the rotating member 126. The rotating member 126 can rotate relative to the connecting member 124 via the second hinge shaft 1246, so that the third stopping portion 1244 abuts against one of the two end portions 1262, 1264 of the arc-shaped slot 1260 to limit the rotating angle of the rotating member 126. As shown in fig. 1 and 3, when the electronic unit 10 is in the landscape mode, the third stopping portion 1244 of the connecting member 124 abuts against the end portion 1262 of the arc-shaped slot 1260.
Referring to fig. 5 to 10, fig. 5 is a perspective view of the electronic unit 10 in fig. 1 during rotation, fig. 6 is a perspective view of the fixed member 122, the connecting member 124, the rotating member 126 and the torsion spring 128 in fig. 5, fig. 7 is a perspective view of the rotating member 126 in fig. 5 at another angle, fig. 8 is a perspective view of the electronic unit 10 in fig. 1 after rotating ninety degrees, fig. 9 is a perspective view of the fixed member 122, the connecting member 124, the rotating member 126 and the torsion spring 128 in fig. 8, and fig. 10 is a perspective view of the rotating member 126 in fig. 8 at another angle.
When the user wants to switch the electronic unit 10 from the landscape mode (shown in fig. 1) to the portrait mode (shown in fig. 8), the user can rotate the electronic unit 10 of fig. 1 in the first direction a1, so that the rotating member 126 rotates along with the electronic unit 10 in the first direction a 1. In this embodiment, when the connecting member 124 rotates relative to the fixing member 122 in the first direction a1, the torsion spring 128 reduces the torsion of the first hinge shaft 1220, so that the torsion of the first hinge shaft 1220 is smaller than the torsion of the second hinge shaft 1246. Therefore, when the user rotates the electronic unit 10 in fig. 1 to the position shown in fig. 5 in the first direction a1, the rotating member 126 and the connecting member 124 are rotated together with the first hinge shaft 1220 with respect to the fixing member 122, i.e., the rotating member 126 and the connecting member 124 are not moved. As shown in fig. 7, since the rotating member 126 rotates together with the connecting member 124 relative to the fixed member 122, the third stopping portion 1244 of the connecting member 124 still abuts against the end portion 1262 of the arc-shaped slot 1260. In addition, as shown in fig. 6, after the rotating element 126 and the connecting element 124 rotate relative to the fixed element 122, the second stopping portion 1242 of the connecting element 124 abuts against the lower edge of the fixed element 122, so that the connecting element 124 cannot rotate in the first direction a1 to limit the rotation angle of the connecting element 124. Therefore, when the user continues to rotate the electronic unit 10 in fig. 5 in the first direction a1, the rotating member 126 is rotated to the position shown in fig. 8 in the first direction a1 relative to the connecting member 124 by the second hinge 1246. As shown in fig. 10, after the rotating member 126 rotates relative to the connecting member 124, the third stopping portion 1244 of the connecting member 124 abuts against the end portion 1264 of the arc-shaped slot 1260, so as to limit the rotating angle of the rotating member 126. Thereby, the electronic unit 10 can be stably maintained in the portrait mode shown in fig. 8. Thus, the rotating piece 126 and the connecting piece 124 rotate together relative to the fixing piece 122 according to the first pivot shaft 1220, so that the height of the rotating piece relative to the frame body changes when the rotating piece rotates, the supporting frame has a lifting function when the rotating piece rotates, and the switching requirements of the user for watching transverse screens and watching vertical screens are met.
When the user wants to switch the electronic unit 10 from the portrait mode (shown in fig. 8) to the landscape mode (shown in fig. 1), the user can rotate the electronic unit 10 in fig. 8 in the second direction a2, such that the rotating member 126 rotates along with the electronic unit 10 in the second direction a 2. In this embodiment, when the connecting member 124 rotates relative to the fixing member 122 in the second direction a2, the torsion spring 128 increases the torsion of the first hinge shaft 1220, such that the torsion of the first hinge shaft 1220 is greater than the torsion of the second hinge shaft 1246. Therefore, when the user rotates the electronic unit 10 in fig. 8 in the second direction a2 to the position shown in fig. 5, the rotating member 126 is first rotated relative to the connecting member 124 by the second hinge shaft 1246. At this time, the connecting member 124 and the fixing member 122 are relatively immovable. As shown in fig. 7, after the rotating member 126 rotates relative to the connecting member 124, the third stopping portion 1244 of the connecting member 124 abuts against the end portion 1262 of the arc-shaped slot 1260 to limit the rotating angle of the rotating member 126. Therefore, when the user continues to rotate the electronic unit 10 of fig. 5 in the second direction a2, the rotating member 126 and the connecting member 124 rotate together along the first hinge shaft 1220 to the position shown in fig. 1 in the second direction a2 with respect to the fixing member 122. At this time, as shown in fig. 2, the first stopping portion 1240 of the connecting member 124 abuts against the upper edge of the fixing member 122, so that the connecting member 124 cannot rotate in the second direction a2 to limit the rotation angle of the connecting member 124. Thus, the electronic unit 10 can be stably maintained in the lateral mode shown in fig. 1.
In this embodiment, the axis of the first hinge shaft 1220 of the fixed member 122 is offset from the center of the rotating member 126.
Therefore, as shown in fig. 5, when the connecting member 124 rotates relative to the fixing member 122 via the first pivot 1220, the electronic unit 10 disposed on the rotating member 126 rotates and moves up and down relative to the frame 120. Since the electronic unit 10 moves up or down simultaneously during the rotation, the electronic unit 10 does not collide with the base 1202 during the rotation. Therefore, the user can easily switch the electronic unit 10 between the horizontal mode (as shown in fig. 1) and the vertical mode (as shown in fig. 8), and the operation is very convenient.
Note that the first direction a1 is opposite to the second direction a 2. For example, when the user faces the electronic device 1, the first direction a1 may be clockwise, and the second direction a2 may be counterclockwise.
Referring to fig. 11 and 12, fig. 11 is a perspective view of a support frame 12 'according to another embodiment of the present invention, and fig. 12 is a partial exploded view of the support frame 12' in fig. 11. The main difference between the support frame 12 'and the support frame 12 is that the first pivot shaft 1220 of the support frame 12' includes a climbing washer 1222, as shown in fig. 11 and 12. In this embodiment, the ramp washer 1222 replaces the torsion spring 128, i.e., the ramp washer 1222 is used to achieve the function of the torsion spring 128. Therefore, when the connecting member 124 rotates relative to the fixing member 122 in the first direction a1, the climbing washer 1222 reduces the torsion of the first hinge shaft 1220, so that the torsion of the first hinge shaft 1220 is smaller than the torsion of the second hinge shaft 1246. When the connecting member 124 rotates relative to the fixing member 122 in the second direction a2, the climbing washer 1222 increases the torsion of the first hinge shaft 1220, such that the torsion of the first hinge shaft 1220 is greater than the torsion of the second hinge shaft 1246.
it should be noted that in the above embodiments, the torsion of the first hinge shaft is increased or decreased by the torsion spring or the climbing washer, so that the torsion of the first hinge shaft is greater or less than the torsion of the second hinge shaft, so that the rotating member 126 and the connecting member 124 rotate relative to the fixed member, and the rotation of the rotating member relative to the connecting member 124 changes sequentially. However, the provision of a torsion spring or a climbing washer is not essential and is merely a preferred embodiment, and in practice, one skilled in the art may choose not to use it. For example, there may be no torsion spring or climbing washer, i.e. there is no need to change the relative magnitude relationship between the torque of the first pivot shaft and the torque of the second pivot shaft, when the user rotates the electronic unit, the electronic unit will lift relative to the frame body when rotating by the cooperation of the rotating member, the connecting member, the fixing member, the first pivot shaft and the second pivot shaft.
In summary, the electronic unit (e.g., the display) can be disposed on the rotating member of the supporting frame. When the user rotates the electronic unit, the electronic unit can generate lifting action relative to the frame body during rotation by the mutual matching of the rotating part, the connecting part, the fixing part, the first pivot rotating shaft and the second pivot rotating shaft. In other words, the support frame of the invention can provide a lifting function when rotating, and the operation is quite convenient. It should be noted that the present invention can also be applied to other objects disposed on the rotating member according to practical applications, and is not limited to disposing the electronic unit.
The present invention has been described in relation to the above embodiments, which are only exemplary of the implementation of the present invention. It should be noted that the disclosed embodiments do not limit the scope of the invention. Rather, it is intended that all such modifications and variations be included within the spirit and scope of this invention.
