When the second connection portion 220 of the support 200 is moved close to the frame 100 by a force, the elastic arm 130A is pressed by the rod 300, such that the second fastening portion 330A is detached from the first fastening portion 120A to release the movable portion 325. Thus, the inclination of the support 200 relative to the frame 100 is adjustable.
In this embodiment, the fix ends 131 of the elastic arms 130A, 130B are closer to the first end 111A of the groove 111 than the movable ends 132 of the elastic arms 130A, 130B. Thus, it is favorable for the movable portion 325 to be guided by the elastic arm 130A or 130B to slide from the second end 111B back to the first end 111A of the groove 111.
In this embodiment, the second fastening portions 330A, 330B are two slots, and the first fastening portions 120A, 120B are two blocks, but the disclosure is not limited thereto. Further, each of the first fastening portions 120A, 120B has a stopping surface 121, and a normal line N of the stopping surface 121 is parallel to the extension axis A1 of the groove 111.
Moreover, in this embodiment, each of the second fastening portions 330A, 330B has a pressing surface 331. An angle θ2 between one of the pressing surfaces 331 and an extension axis A2 of the bar portion 310 is different from an angle θ2′ between the other of the pressing surfaces 331 and the extension axis A2. The two pressing surfaces 331 respectively correspond to the two stopping surfaces 121. Please refer to FIG. 6 in advance, when the second fastening portion 330A is fastened with the first fastening portion 120A, there is an angle θ1 between the extension axis A1 of the groove 111 and the extension axis A2 of the bar portion 310, and there is the angle θ2 between the pressing surface 331 and the extension axis A2. A sum of the angles θ1 and θ2 (θ1+θ2) can be equal to 90 degrees. In this embodiment, take the quantity of the second fastening portions 330A, 330B to be two for further explanation. As shown in FIG. 6, when the second fastening portion 330A is fastened with the first fastening portion 120A, the angle θ1 can be 70 degrees, and the angle θ2 can be 20 degrees. Please refer to FIG. 8 in advance, when the second fastening portion 330B is fastened with the first fastening portion 120B, the angle θ1′ can be 47.5 degrees, and the angle θ2′ can be 42.5 degrees.
As shown in FIG. 6, each of the rods 300 can includes two third fastening portions 340A, 340B. The third fastening portions 340A, 340B and the second fastening portions 330A 330B are all located on the same end of the rod 300. The second fastening portions 330A 330B and the third fastening portions 340A, 340B are symmetrical about the extension axis A2 of the bar portion 310. An advantage of the rod 300 including the second fastening portions 330A, 330B and the third fastening portions 340A, 340B is that the rod can have better commonality; that is, the rod 300 is applicable no matter which side of the frame 220 does the rod 300 is disposed, and it is also favorable for assembling the rod 300 without considering assembling direction so as to improve the assembling efficiency.
Please refer to FIG. 5 through FIG. 10, which are schematic views of using the portable electronic device in FIG. 1. In this embodiment, a user is able to fully open the support 200 by one hand.
As shown in FIG. 4B, FIG. 5 and FIG. 6, when the support 200 is fully opened, the rod 300 is pressed by the elastic arm 130A such that the second fastening portion 330A is fastened with the first fastening portion 120A. At this state, the movable portion 325 is fixed to the second end 111B of the groove 111, and there is an inclination Φ between the body 100 and a supporting surface (its reference number is omitted). The inclination Φ is, for example, 115 degrees. Furthermore, since the angle θ1 (70 degrees) and the angle θ2 (20 degrees) are complementary angles, it is favorable for the stopping surface 121 of the first fastening portion 120A to be firmly abutted against the pressing surface 331 of the second fastening portion 330A, thereby stopping the movement of the support 200 to improve stability.
As shown in FIG. 4B, FIG. 7 and FIG. 8, the user is able to apply a force F to press a side of the second connection portion 220 away from the frame 100. In this embodiment, the force F can be greater than 7.7 gw and less than 1 kgw. When the second connection portion 220 is pressed by the force F, the second connection portion 220 is moved to drive the rod 300 to press the elastic arm 130A, such that an empty space in the groove 111 is generated. Therefore, the second fastening portion 330A is detached from the first fastening portion 120A, and the movable portion 325 of the rod 300 can be slid in the empty space to move toward the first end 111A of the groove 111. Thus, the second connection portion 220 of the support 200 is moved close to the frame 100, and the second fastening portion 330B is fastened with the first fastening portion 120B. At this state, an inclination Φ′ is between the body 100 and the supporting surface. The inclination Φ′ is, for example, 114.5 degrees. Furthermore, since the angle θ1′ (47.5 degrees) and the angle θ2′ (42.5 degrees) are complementary angles, it is favorable for the stopping surface 121 of the first fastening portion 120B to be firmly abutted against the pressing surface 331 of the second fastening portion 330B, thereby stopping the movement of the support 200 to improve stability.
As shown in FIG. 4B, FIG. 7, FIG. 9 and FIG. 10, the user is able to apply a force (shown by the arrow F) again by one hand to press the side of the second connection portion 220 away from the frame 100. When the second connection portion 220 is pressed, the second connection portion 220 is moved to drive the rod 300 to press the elastic arm 130B, such that the empty space in the groove 111 is generated. Therefore, the second fastening portion 330B is detached from the first fastening portion 120B, and the movable portion 325 of the rod 300 can be slid in the empty space to further move toward the first end 111A. Thus, the second connection portion 220 is further moved close to the frame 100, such that the support 200 is fully closed.
In this embodiment, for the configuration of one rod 300 with one groove 111, the first fastening portion, the elastic arm and the second fastening portion are all two in quantity, but the disclosure is not limited thereto. In some other embodiments, the first fastening portion, the elastic arm and the second fastening portion can be one in quantity for the configuration of one rod with one groove.
The frame 100 and the case 12 of the body 10 are two independent pieces in the aforementioned embodiment, but the disclosure is not limited thereto. Please refer to FIG. 11, which is a perspective view of a portable electronic device according to another embodiment. Since this embodiment is similar to the aforementioned embodiment, only the differences will be illustrated hereafter.
The frame 100 of the portable electronic device 1 in this embodiment is integral with the case 12 of the body 10 in the aforementioned embodiment, and the electronic member 14 is disposed in the frame 100. Thus, the frame 100 is favorable for being assembled with the support 200, and protecting the electronic member 14.
According to the disclosure, the second fastening portion can be fastened with the first fastening portion to fix the position of the support, and the second fastening portion is detachable from the first fastening portion to release the support when the elastic arm is pressed. Therefore, the user is able to open, position and close the support by one hand, and thereby the operation for standing the electronic device is simplified. Also, the electronic device is capable of standing on the supporting surface more stably by the interaction among the first fastening portion, the second fastening portion and the elastic arm.
