Effect.

Please refer to FIG. 5B and FIG. 6B at the same time. In this embodiment, the fixing seat 141 of the pulley module 140 has two slide grooves 141 - 1 extending along the Z axis. The two movable pulleys 144 are respectively slid on the two chute 141-1, wherein the two chute 141-1 has a length LD in the direction of the Z axis, and the length LD is the stroke of the two movable pulleys 144 moving on the fixed seat 141 .

As mentioned above, since the two movable pulleys 144 are pivotally connected to the sliding member 142, and the sliding direction of the two movable pulleys 144 (ie, the direction parallel to the Z-axis) is parallel to the stretching direction of the first elastic member 146 (ie, the direction parallel to the Z-axis) , when the first elastic member 146 stretches and stretches, the sliding member 142 can pass through the two movable pulleys 144 and slide in parallel along the two sliding slots 141-1 in the Z-axis direction, so as to be able to move up and down stably.

Please refer to FIG. 5A to FIG. 6B at the same time. In this embodiment, the electronic device 100 further includes a turning pulley 147 and a fixing member 148 . The diverting pulley 147 and the fixing member 148 are disposed on the fixing base 141 , and the fixed pulley 143 is located between the diverting pulley 147 and the fixing member 148 along the Y-axis direction. The pull cord 145 includes opposite ends E1, E2. one end E1 is fixed on the fixing base 141 through the fixing member 148 , and the other end E2 is connected to the display unit 120 . The pull cord 145 winds around the two movable pulleys 144 and the fixed pulley 143 to the diverting pulley 147 from one end E1 to change the direction of the pull cord 145 so as to smoothly pass through the device main body 110 and connect the other end E2 to the display unit 120 .

As shown in FIG. 5B , when the display unit 120 is at the initial position SP, there is a first distance D1 between the other end E2 of the pull cord 145 and the diverting pulley 147 . As shown in FIG. 6B , when the display unit 120 moves to the raised position FP ( FIG. 6A ), there is a second distance D2 between the other end E2 of the pull cord 145 and the diverting pulley 147 . The first distance D1 is greater than the second distance D2, and the difference between the first distance D1 and the second distance D2 is the travel distance for the display unit 120 to move from the initial position SP to the raised position FP.

Here, it should be noted that, according to the mechanical characteristics of the movable pulley 144, when the stroke of the display unit 120 from the initial position SP to the raised position FP is the difference between the first distance D1 and the second distance D2, each time the pulley 145 is wound around a movable pulley 144, which can shorten the moving stroke of the stay rope 145 in the pulley module 140 to one-half of the original moving stroke (ie the difference between the first distance D1 and the second distance D2). In other words, the stroke of the display unit 120 moving from the initial position SP to the raised position FP is twice the stroke of a movable pulley 144 moving on the fixed seat 141 .

Therefore, in the present embodiment, since each pulley module 140 includes two movable pulleys 144, the travel of the two movable pulleys 144 moving on the fixed seat 141 (that is, the length LD of the chute 141-1) can be shortened to the original moving 1/4 of the stroke (that is, the difference between the first distance D1 and the second distance D2 ), and at the same time, the stretching amount of the first elastic member 146 is shortened to 1/4 of the original moving stroke.

For example, the rising stroke (along the Z axis) of the display unit 120 moving from the starting position SP to the lifting position FP in this embodiment is, for example, 80 mm, and the descending stroke (along -Z axis) of the two movable pulleys 144 on the fixed seat 141 Axial direction) is, for example, 20 mm, and the stretching amount of the first elastic member 146 is, for example, 20 mm. In other embodiments, the lifting and falling strokes and the stretching amount of the elastic member can be adjusted according to requirements, and are not limited thereto.

As mentioned above, in the electronic device 100 of this embodiment, the pulley module 140 can shorten the moving stroke of the pull cord 145 in the pulley module 140 by setting the movable pulley 144, and at the same time shorten the pulling force of the first elastic member 146. stretch.

Compared with the conventional electronic device, the elastic member is directly used to drive the display unit to move relative to the main body of the device to the raised position, so that the elastic member needs a longer pre-stretch to achieve the above action. The electronic device 100 of this embodiment can adjust the number of movable pulleys 144, that is, shorten the moving stroke of the pull cord 145 and the stretching amount of the first elastic member 146, so as to reduce the required space of the pulley module 140 in the device main body 110 , so as to reduce the restrictions on the external dimensions of the device main body 110 caused by the lifting action.

In addition, please refer to FIG. 5A to FIG. 6B , in this embodiment, the electronic device 100 further includes four damping elements 149 . In each pulley module 140 , two damping elements 149 are disposed between the fixing seat 141 and the sliding element 142 along the Z-axis direction, and the first elastic element 146 is located between the two damping elements 149 along the Y-axis direction. In this way, the setting of the damping member 149 can reduce the speed at which the first elastic member 146 shrinks and returns, and at the same time reduce the speed at which the display unit 120 moves to the raised position FP relative to the device main body 110, so as to prevent the electronic device 100 from being lifted too fast due to the display unit 120 being raised. Fast and produce impact and noise.

To sum up, in the electronic device of the present invention, through the fastener and the fixed The snapping and positioning relationship of the positioning part, the snapping relationship between the main body of the device and the display unit is selected, and after the snapping and positioning of the snapping part and the positioning part are released, the pulley module drives the display unit to move relative to the main body of the device to the raised position , so as to increase the height of the display unit, so that the user can view the display unit at a more comfortable height. Moreover, the pulley module of the present invention can shorten the moving stroke of the stay rope in the pulley module by setting the movable pulley, and at the same time shorten the stretching amount of the first elastic member. Accordingly, the electronic device of the present invention can adjust the number of movable pulleys, that is, shorten the moving stroke of the pull cord and the stretching amount of the first elastic member, so as to reduce the space required for the pulley module in the main body of the device, thereby reducing the above-mentioned Lifting action limits the size of the electronic device.

Although the present invention has been disclosed above with the embodiments, it is not intended to limit the present invention. Anyone with ordinary knowledge in the technical field may make some changes and modifications without departing from the spirit and scope of the present invention. The scope of protection of the present invention should be defined by the scope of the appended patent application.
