The first magnetic element 20 is, for example, disposed on a maintenance fixture (not The electronic device 10 is adapted to be housed in a maintenance fixture. When the electronic device 10 is placed in the maintenance jig, the first magnetic element 20 can be adjacent to the electronic device 10 near the position of the second magnetic element 140 for maintenance and assembly. However, the present invention does not limit the structure and arrangement of the first magnetic element 20 herein.

In the embodiment, the second engaging portion 130 is attracted to the first magnetic element 20 by the second magnetic element 140. The second magnetic element 140 includes a metal or a magnet. In other words, the second engaging portion 130 is, for example, a plastic injection molded hook, and a magnet is embedded on the second engaging portion 130 such that when the first magnetic element 20 (shown in FIG. 2A ) is close to the electronic At the time of the device 10, the second engaging portion 130 can be attracted to rotate. In other embodiments not shown in the present invention, the second engaging portion may also be formed of a metal member that can be magnetically attracted. The present invention does not limit the composition relationship of the second engaging portion and the second magnetic attraction member herein.

2B is a schematic diagram of the electronic device of FIG. 1B. In FIG. 2B, the structure of the second engaging portion 130 is clearly shown, and some parts of the electronic device 10 are omitted. Referring to FIG. 2B , when the second engaging portion 130 is reset to the first position, the first body 12 includes the stopping portion 13 . The stopping portion 13 is for restricting the second engaging portion 130 from staying at the first position. In other words, the stopper portion 13 can prevent the second engaging portion 130 from being continuously pushed to a position beyond the first position after the elastic member 120 releases the elastic potential energy. When the second body 14 is to be assembled again, the first engaging portion 110 can no longer re-engage with the second engaging portion 130.

In this embodiment, the second body 14 is assembled back to the side of the first body 12. For example, the first magnetic element 20 can be brought close to the second magnetic element 140 by the above method, so that the second engaging portion 130 is in the second position shown in FIG. 2A, and then the second body 14 is assembled. However, the invention is not limited to this assembly. The following is a description of the assembly method.

In detail, when the second body 14 is assembled back to the first body 12, the first engaging portion 110 on the second body 14 is in contact with the second engaging portion 130 stopped at the first position (as shown in FIG. 3A). Show). In FIG. 3B , the first inclined surface 112 of the first engaging portion 110 and the second inclined surface 132 of the second engaging portion 130 abut each other, such that the first inclined surface 112 pushes the second inclined surface 132 to drive the second engaging portion 130 . Rotation with respect to the first body 12 until the second engaging portion 130 reaches the second position (as shown in FIG. 3C).

During the rotation of the second engaging portion 130 (as shown in FIGS. 3B and 3C), the elastic member 120 accumulates elastic potential energy. After the first slope 112 is separated from the second slope 132, there is no longer a component that interferes with the first engagement portion 110 in the assembly path of the first engagement portion 110. The head portion 134 of the second engaging portion 130 and the head portion 114 of the first engaging portion 110 abut each other until the second body 14 is reassembled back onto the first body 12, and the head of the first engaging portion 110 The portion 114 no longer abuts the head 134 of the second engaging portion 130. second The engaging portion 130 can be returned to the first position by releasing the elastic potential energy by the elastic member 120. To constitute a structural interference as shown in FIG. 1B.

In summary, the electronic device of the present invention has a snap structure capable of attracting the first magnetic member by the second magnetic element, so that the second engaging portion moves between the first position and the second position, Changing the engagement state of the second body and the first body. When the second engaging portion is in the first position, the second engaging portion and the first engaging portion constitute structural interference. When the second engaging portion is located at the second position, the second engaging portion is disengaged from the first engaging portion. Therefore, in the present invention, the engaging structure can prevent damage of the component due to improper application when the second body of the electronic device is detached from the first body. In addition, the second engaging portion is locked to the first engaging portion by pivoting, and the requirement of the second engaging portion for the elastic arm is reduced, so that the height of the second engaging portion can also be reduced. The electronic device with the snap structure can reduce the thickness. In addition, a blocking portion may be further disposed on the first body of the electronic device to limit the second card when the second body is detached from the first body and the second engaging portion is reset from the second position. The joint stays in the first position for subsequent assembly.
