The present invention relates to an electronic device, and in particular to a portable electronic device.

Tablet computers are common portable electronic devices that can provide larger display screens or operation screens, and have become an important tool for modern people in work or life. Generally speaking, the common operation method of tablet computers is handheld operation, but over a long period of time, it causes a great burden to the user. Therefore, a design of integrating a stand into a tablet computer has been proposed. In detail, the user must manually flip the stand to unfold the stand relative to the tablet computer so that the tablet computer can stand on the work surface through the stand. In addition, the user can only increase or decrease the unfolding angle between the tablet computer and the stand to adjust the viewing angle of the tablet computer, and cannot adjust the viewing height of the tablet computer. In other words, the design of the stand commonly integrated into the tablet computer is relatively insufficient in terms of operational mobility and convenience.

The present invention provides a portable electronic device with excellent operational mobility and convenience.

The present invention proposes a portable electronic device, including a display body, a base, a bracket and a first torsion spring.

FIG. 3C is a cross-sectional schematic diagram of FIG. 3B switching to the third operation mode. Referring to FIG. 2A and FIG. 3A, in this embodiment, the bracket 130 is disposed between the base 120 and the display body 110, and has a first end 131 pivotally connected to the base 120 and a second end 132 pivotally connected to the display body 110. In the first operation mode, the back surface 112 of the display body 110 contacts or adheres to the base surface 121 of the base 120, and the base hook 122 is engaged with the body hook 113, so that the bracket 130 is positioned between the base 120 and the display body 110.

Specifically, the portable electronic device 100 further includes a first torsion spring 140 disposed corresponding to the first end 131, and the two ends of the first torsion spring 140 are respectively connected to the base 120 and the bracket 130. In the first operation mode, the first torsion spring 140 is squeezed by the base 120 and the bracket 130. Once the engagement relationship between the display body 110 and the base 120 is released, the elastic force of the first torsion spring 140 can drive the base 120 to rotate and unfold relative to the bracket 130 and the display body 110, as shown in FIG. 2B, FIG. 2C and FIG. 3B.

Please refer to FIG. 1A, FIG. 2A and FIG. 2B. In this embodiment, the portable electronic device 100 further includes a control element 150 disposed on the base 120, wherein the control element 150 is coupled to the base hook 122 and is used to drive the base hook 122 to rotate. Specifically, the control element 150 includes a switch key 151 and a control circuit 152 coupled to the switch key 151, and the switch key 151 is disposed on the side 124 of the base 120. In addition, the control circuit 152 is disposed in the base 120 and coupled to the base hook 122 to drive the base hook 122 to rotate.

As shown in FIG. 1A and FIG. 2B , when the user touches or presses the switch button 151, the control circuit 152 is energized to drive the base hook 122 to rotate around the first rotation direction R1. As shown in FIG. 2B , FIG. 2C and FIG. 3B , after the engagement relationship between the display body 110 and the base 120 is released, the base 120 can automatically rotate and unfold relative to the display body 110. For the user, the portable electronic device 100 is not only easy to operate, but also has excellent operational mobility.

Afterwards, as shown in FIG. 1A , FIG. 2B and FIG. 2C , the user may stop touching or pressing the switch button 151 and stop energizing the control circuit 152 . Once the control circuit 152 is de-energized, the base hook 122 may rotate back around the second rotation direction R2 , as shown in FIG. 2C . For example, in the process of returning from the second operation mode to the first operation mode, the back surface 112 of the display body 110 is brought close to the base surface 121 of the base 120 , and the body hook 113 contacts the base hook 122 and pushes the base hook 122 to rotate around the first rotation direction R1 , so that the body hook 113 smoothly moves through the base hook 122 and is inserted into the base slot 123 , as shown in FIG. 2A to FIG. 2C . When the body hook 113 is inserted into the base slot 123, the base hook 122 is inserted into the body slot 114 and rotates back around the second rotation direction R2 to engage with the body hook 113.

As shown in FIG. 3A and FIG. 3B , the display body 110 further has a body magnetic part 115, and the bracket 130 further has a bracket magnetic part 133 arranged corresponding to the body magnetic part 115.

In the first operating mode and the second operating mode, the bracket magnetic part 133 is magnetically attracted to the body magnetic part 115, so that the bracket 130 is attached to the display body 110. On the other hand, the portable electronic device 100 further includes a second torsion spring 160 arranged corresponding to the second end 132, and the two ends of the second torsion spring 160 are respectively connected to the display body 110 and the bracket 130. In the first operation mode and the second operation mode, the second torsion spring 160 is squeezed by the body 110 and the bracket 130, and the elastic force of the second torsion spring 160 is smaller than the magnetic attraction between the bracket magnetic part 133 and the body magnetic part 115.

As shown in FIG. 3B and FIG. 3C , when the bracket 130 is separated from the display body 110 , the magnetic attraction between the bracket magnetic part 133 and the body magnetic part 115 is weakened and is smaller than the elastic force of the second torsion spring 160 , so that the display body 110 is driven by the second torsion spring 160 to rotate and unfold relative to the bracket 130 .

Please refer to FIG. 1D and FIG. 3A to FIG. 3C. In this embodiment, the display body 110 also has a groove 116 located on the back surface 112 and used to accommodate a portion of the bracket 130. In addition, the base 120 also has a groove 125 located on the base surface 121 and used to accommodate another portion of the bracket 130.
