[Second Embodiment]

Please refer to FIG. 6 to FIG. 10 , which shows an electronic device 100a according to a second embodiment of the present invention. The main difference from the first embodiment is that this embodiment is provided with two connectors 30a. The connecting piece 30a is slidably disposed on the bottom surface of the cover 10a, and can be located in a locking position or an unlocking position, so that the cover 10a is fixed to the housing 20a in a snap-on manner after assembly. However, the present invention is not limited thereto. The number of connectors may be more than one, depending on the shape and size of the cover 10 .

As shown in FIG. 6 , each connecting member 30a includes a plate-shaped body 34 and a plurality of sliding hooks 31 . A plurality of sliding hooks 31 are provided on the plate-shaped body 34 . The connector 30a in this embodiment may be a metal plate that is stamped or injection molded from plastic. The plurality of sliding hooks 31 are integrally formed on the plate-shaped body 34 through stamping.

Corresponding to the two connectors 30a, the two sides of the assembly wall 22 of the housing 20a each include a plurality of sliding holes 221a, 222a. When the connector 30a is in the locking position, the sliding hook 31 is correspondingly engaged with the sliding hole. Contact holes 221a, 222a.

Regarding the manner in which the connecting member 30a is slidably disposed on the cover 10a, specifically, the plate-shaped body 34 of each connecting member 30a has two elongated through holes 33. In this embodiment, the retaining member S is used to pass through each elongated through hole 33 and be fixed to the cover plate 10 , thereby restricting the connecting member 30 from sliding relative to the cover plate 10 within the elongated through hole 33 . In this embodiment, the retaining member S may be a screw. Correspondingly, the plate-shaped body 34 forms a screw-connecting portion 15 similar to a nut for the retaining member S to be screwed to the plate-shaped body 34 . However, the present invention is not limited thereto. For example, the holding member may be a hot melt column.

In addition, the connecting piece 30a also has a plurality of elastic parts 32. The elastic parts 32 are integrally formed on the plate-shaped body 34. Both sides of the elastic part 32 are hollow-shaped. The elastic parts 32 protrude toward the cover 10 and are slightly V-shaped. and abuts against the cover 10 . Thereby, the connecting piece 30a can contact the cover 10 urgently to avoid accidental sliding.

As shown in FIG. 6 , the method of moving the connecting member 30a in this embodiment is specifically described as follows. The connecting member 30a forms a force applying part 37, and the force applying part 37 may be a small round hole. The assembly wall 22 of the cover plate 10a forms a hollow operation hole 227. The length of the operation hole 227 is greater than the length of the force application part 37. The orthographic projection of the force application part 37 onto the assembly wall 22 overlaps the operation hole 227. However, the present invention is not limited thereto. The force-applying portion 37 can be a component protruding from the operating hole 227 and can allow the operator to move the connecting member 30a.

After the electronic device 100a of this embodiment is assembled, it is shown in FIG. 7 and FIG. 8 . The cover 10a is fixedly assembled to the casing 20a, and the assembly structure between the cover 10a and the casing 20a is completely hidden inside the electronic device 100a. The appearance of the electronic device 100a does not expose any fixed components.

As shown in FIG. 9 and FIG. 9A , the connecting member 30a of this embodiment is shown in the unlocking position. At this time, the force applying part 37 is adjacent to one end of the operating hole 227 (please also refer to the dotted line at the bottom of Figure 8 to indicate the position of the force applying part 37 when unlocking, which is close to the left end of the operating hole 227). At the same time, the sliding hook 31 is only located in the sliding hole (221a, 222a) and is not engaged. The operator can use a moving tool from the inside of the housing 20 to push the force applying part 37 in the operating hole 227 , see the moving direction D1 in FIG. 8 . This allows the connecting piece 30a to be moved.

As shown in FIG. 10 and FIG. 10A , by applying force to the other end of the force applying part 37 adjacent to the operation hole 227 , the connector 30 a is moved to the locking position (please also refer to FIG. 8 , the force applying part is represented by the solid line). 37, near the right end of operating hole 227). At this time, the sliding hook 31 slides and engages in the sliding holes (221a, 222a). Thereby, the connecting member 30a securely assembles the cover 10a to the housing 20a. In addition, this embodiment uses the elastic force provided by the elastic portion 32 of the connecting member 30a to make the sliding hook 31 of the connecting member 30a press against the periphery of the sliding holes (221a, 222a). Through friction, the connecting member 30a cannot Will loosen and slide.

Supplementary explanation, the assembly wall 22 forms two shallow accommodation grooves 225 , the positions of the two shallow accommodation grooves 225 correspond to the positions of the two connectors 30 a , and the length of the shallow accommodation grooves 225 is greater than the length of the plate-shaped body 34 , the plate-shaped body 34 can slide in the shallow accommodation groove 225 .

The advantage of this embodiment is that the operator can move the connecting member 30a from the locked state in Figure 10 to the unlocked state in Figure 9, and the cover 10a can be detached from the housing 20a.

[Beneficial effects of the embodiment]

One of the beneficial effects of the present invention is that the electronic device provided by the present invention can use "the plurality of fixed hooks of the cover plate to correspond to the plurality of engagement holes of the housing" and The structure of "at least one connector disposed between the assembly wall and the cover to fix the cover to the housing" can completely hide the assembly structure inside the electronic device 100 to improve the electronics The aesthetics of the device 100.
