Referring to FIG. 4A and with reference to FIG. 2, the back plate 70 has a first side 71 (second drawing) and a second side 72 facing each other. The first side 71 has a hook 711 (Fig. 2), and the second side 72 of the back plate 70 includes two mounting sleeves 721, 725. The two mounting sleeves 721, 725 are located at the second side 72. On both sides, the two mounting sleeves 721, 725 respectively have a through hole 722, 726, wherein the through holes 722, 726 have different structural forms.

In one embodiment, the shaft 60 and the backing plate 70 and the two cover members 80 are assembled and then coupled to the base 10 (Fig. 2). The manner in which the rotating shaft 60 connects the back plate 70 and the two covering members 80 is as follows: First, as shown in FIG. 4A, one end 63 of the rotating shaft 60 is inserted into the through hole 726, and the other end 61 of the rotating shaft 60 is inserted into the through hole. In 722, the rotating shaft 60 is clamped in the two mounting sleeves 721, 725. It should be noted that since the through hole 726 has an asymmetrical structural form, the rotating shaft 60 can be inserted therein in a skewed manner, which facilitates assembly of the rotating shaft 60 and the backing plate 70. Then, as shown in FIG. 4B, two cover members 80 are covered on the outer sides of the two mounting sleeves 721 and 725, wherein the two cover members 80 respectively have a convex shaft 801, and the cover member 80 covers the two covers 80.

Figure 4B).

The operation mode of the electronic device support base 1 of this embodiment is explained as follows. As shown in FIG. 6, the backing plate 70 is superposed on the base 10 when the backing plate 70 is in the first position. At this time, as shown in FIG. 7, the second engaging structure 207 of the coupling member 20 is engaged with the hook 711 of the backing plate 70. Moreover, as shown in FIG. 5, the first engaging structure 205 of the coupling member 20 is engaged in one of the grooves 607. It should be noted that since the depth extending direction of the groove 507 of the rotating shaft 60 is not perpendicular to the outer side surface 601a of the rotating shaft 60, the first engaging structure 205 of the bonding member 20 is clamped in the groove 607.

Please refer to Figure 3A again, with reference to Figures 5, 7, and 8. When the electronic device support 1 is used to support the portable electronic device, the two control components 40 are pressed, and the drive coupling 20 is moved in a predetermined direction X to release the back plate 70 and the rotating shaft 60. In detail, when the second end 43 of the two control assemblies 40 is pressed by an external force, the two control assemblies 40 begin to move toward the beveled structure 209 of the coupling member 20 and abut against the first end 41. With the control assembly 40 abutting, the coupling member 20 begins to move in a predetermined direction X, the first engaging structure 205 of the coupling member 20 is separated from one of the grooves 607 (Fig. 5), and the second card of the coupling member 20 is caused. The joint structure 207 is separated from the hook 711 of the backing plate 70 (Fig. 7).

Since the rotating shaft 60 is not limited by the first engaging structure 205 of the coupling member 20, the backing plate 70 can be pivoted relative to the base 10 and adjusted to an appropriate second position to form an angle between the backing plate 40 and the base 10. Between, as shown in Figure 8. After determining the support angle between the backing plate 40 and the base 10, the two control assemblies 70 are released. At this time, the two control assemblies 70 are respectively moved in the direction away from the bevel structure 209 by the restoring force provided by the two second elastic members 50, and the coupling member 20 is biased toward the rotating shaft 60 by the restoring force provided by the first elastic member 30. The direction moves and re-engages the groove 607 of the shaft 60, thereby defining the rotation of the shaft 60. Therefore, a pre-adjusted support angle is maintained between the backboard 70 and the base 10 to stably support the portable electronic device.

Referring to FIG. 8 , in some embodiments, the electronic device support 1 further includes a connector 90 for signal-connecting the portable electronic device. The connecting hooks 90 are pivotally mounted on the pair of carrying brackets 113 of the base 10 and electrically connected to a circuit board (not shown) disposed inside the base 10 for power transmission or signal transmission. For example, the portable electronic device can be further expanded by a USB slot, an HDMI slot, an E-sata slot, an audio slot or a power socket on the electronic device support base 1. In other embodiments, the electronic device support 1 further includes a weight (not shown) disposed inside the base 10 to maintain the balance of the electronic device support 1 . When the electronic device support 1 supports the portable electronic device, it does not fall.

The electronic device support base of the invention can enter between the storage state and the use state The line adjustment is carried out when the portable electronic device needs to be supported, and has the advantages of small size and easy storage compared with the conventional electronic device support. In one embodiment, the electronic device support of the present invention has a size of 130*50*11 mm. In addition, the electronic device support can quickly adjust the support angle of the electronic device support by two control components to meet the viewing angle requirements of different portable electronic devices.
