DETAILED DESCRIPTION OF DISCLOSED EMBODIMENTS


FIG. 1 is a three-dimensional view of an electronic device according to an embodiment of the invention. FIG. 2 is a partial exploded view of the electronic device of FIG. 1. FIG. 3 is a three-dimensional view of a cover and an assembling structure of the electronic device of FIG. 1. Referring to FIG. 1 to FIG. 3, the electronic device 100 of the present embodiment is, for example, networked attached storage (NAS) equipment and includes a main body 110, a cover 120 and an assembling structure 130. The main body 110 has at least one first positioning structure 112a (two first positioning structures 112a are illustrated) and at least one first positioning structure 112b (two first positioning structures 112b are illustrated), and the first positioning structures 112a and the first positioning structures 112b are, for example, positioning holes. The assembling structure 130 is disposed on the cover 120, and the main body 110 and the cover 120 can be assembled through the assembling structure 130.


In detail, the assembling structure 130 includes a sliding component 132a, a sliding component 132b, at least one second positioning structure 134a (two second positioning structures 134a are illustrated) and at least one second positioning structure 134b (two second positioning structures 134b are illustrated), an elastic component 136a and an elastic component 136b. The sliding component 132a is slidably disposed on the cover 120 along a first axis A1 and has a pressing portion P, the sliding component 132b is slidably disposed on the cover 120 along a first axis A1′ and has a pressing portion P′. The second positioning structures 134a and the second positioning structures 134b are respectively connected to the sliding component 132a and the sliding component 132b and are respectively aligned to the first positioning structures 112a and the first positioning structures 112b. The second positioning structures 134a and the second positioning structures 134b are, for example, positioning posts adapted to be inserted into the corresponding positioning holes. The elastic component 136a and the elastic component 136b are connected to the cover 120 and are respectively connected to the sliding component 132a and the sliding component 132b.



FIG. 4A illustrates a situation that the second positioning structures of FIG. 2 are positioned at the first positioning structures. FIG. 4B illustrates a situation that the second positioning structures of FIG. 2 are moved away from the first positioning structures. As shown in FIG. 4A, when the cover 120 is assembled to the main body 110, the second positioning structures 134a are positioned at the corresponding first positioning structures 112a by an elastic force of the corresponding elastic component 136a, and the second positioning structures 134b are positioned at the corresponding first positioning structures 112b by an elastic force of the corresponding elastic component 136b, so as to stop the cover 120 separating from the main body 110. As shown in FIG. 4B, when the pressing portion P and the pressing portion P′ bear forces at the same time to drive the second positioning structures 134a and the second positioning structures 134b to respectively move away from the first positioning structures 112a and the first positioning structures 112b, the cover 120 is adapted to separate from the main body 110 along a second axis A2 perpendicular to the first axis A1 and the first axis A1′ shown in FIG. 2.


Under the above configuration, the user can respectively move the second positioning structures 134a and the second positioning structures 134b away from the first positioning structures 112a and the first positioning structures 112b by only pressing the pressing portion P on the sliding component 132a and the pressing portion P′ on the sliding component 132b at the same time, so as to conveniently disassemble the cover 120. When the user unintentionally presses the pressing portion P, only the second positioning structures 134a are moved away from the corresponding first positioning structures 112a without moving the second positioning structures 134b away from the corresponding first positioning structures 112b. Similarly, when the user unintentionally presses the pressing portion P′, only the second positioning structures 134b are moved away from the corresponding first positioning structures 112b without moving the second positioning structures 134a away from the corresponding first positioning structures 112a. In this way, the cover 120 is effectively prevented from being unexpectedly dissembled to cause danger.

The first rib plate 138a of the present embodiment has an orientation slot T shown in FIG. 7, where the orientation slot T is connected to the first opening H1, and the sliding component 132a has an orientation ridge R shown in FIG. 6. When the sliding component 132a penetrates through the first opening H1 of the first rib plate 138a along the first axis A1 as that shown in FIG. 3, the orientation ridge R is engaged to the orientation slot T to prevent unexpected rotation of the sliding component 132a along the first axis A1. Moreover, unexpected rotation of the sliding component 132b along the first axis A1′ can be prevented through a similar structure and method, which is not repeated.


A method for assembling the sliding component 132a shown in FIG. 6 to the cover 120 shown in FIG. 5 is described below with reference of figures. FIG. 8 is a flowchart illustrating an assembling method for assembling the sliding component of FIG. 6 to the cover of FIG. 5. FIG. 9A to FIG. 9D illustrates assembling steps of FIG. 8.

In this way, it is guaranteed that the sliding component 132a is not assembled in a wrong way by penetrating through the second section h2. Moreover, it is also guaranteed that the sliding component 132b is not assembled in the wrong way according to a similar structure and method, which is not repeated.


In summary, in the electronic device of the invention, the main body has two first positioning structures, the assembling structure has two second positioning structures, and the two second positioning structures are adapted to be simultaneously positioned at the two first positioning structures to assemble the cover to the main body. The user is capable of moving the two second positioning structures away from the two first positioning structures by only pressing the two pressing portions on the two sliding components at the same time, so as to conveniently disassemble the cover. Moreover, when the user unintentionally presses one of the two pressing portions, only one of the two second positioning structures is moved away from the corresponding first positioning structure without moving the other second positioning structure away from the corresponding first positioning structure, by which the cover is effectively prevented from being unexpectedly dissembled to cause danger.
