And achieve its assembly effect. In addition to allowing the radiator body of the antenna module to partially protrude through the opening and protrude beyond the shielding case, the structural features allow the user to disassemble the antenna module without stepping through the pieces. Therefore, the antenna module of the present invention and the electronic device using the same can effectively improve the disassembly and assembly efficiency thereof.

The above described features and advantages of the present invention will be more apparent from the following description.

1 is a schematic diagram of an electronic device in accordance with an embodiment of the invention. Figure 2 is a cross-sectional view of the electronic device of Figure 1 taken along the plane A1. Referring to FIG. 1 and FIG. 2 simultaneously, in the embodiment, the electronic device 100 is, for example, an all-in-one computer, which includes an antenna module 110, a circuit board module 120, and a display module. 130 and a casing 140. However, the present invention is not limited thereto. In other embodiments not shown, the electronic device may be other related devices having the antenna module 110.

In this embodiment, the display module 130 is, for example, a liquid crystal display, which is assembled to the casing 140 and can be opened relative to the casing 140 to facilitate maintenance by relevant personnel. When the display module 130 is closed relative to the casing 140, the two form an accommodating space R1 for accommodating the circuit board module 120 and the antenna module 110. Furthermore, the antenna module 110 includes a shielding housing 112 and an antenna 114. The shielding housing 112 has an opening 112a communicating with the first side S1 and the second side S2, and the circuit board module 120 is, for example, an integrated computer. The motherboard is disposed in the shielding housing 112 and is located on the first side S1.

The antenna 114 is, for example, a Planar Inverted F Antenna (PIFA) or a Dipole Antenna, which is electrically connected to the circuit board module 120. The antenna 114 includes a base 114a and a radiator 114b. It should be noted here that the pedestal 114a is detachably assembled into the shielding case 112 from the same first side S1 as the circuit board module 120, so that the radiator 114b disposed on the pedestal 114a passes through the opening 112a. And worn out of the shielding shell 112. In other words, the pedestal 114a is assembled to the shielding case 112 in a direction D1, and is assembled with the circuit board module 120 at the first side S1 of the shielding case 112 after assembly (ie, the circuit board module 120 is also This direction D1 is assembled to the shield housing 112), whereby a portion of the radiator 114b is allowed to pass through the opening 112a to be positioned on a second side S2 of the shield housing 112. This allows the antenna 114 to function properly as the radiator 114b protrudes out of the shield housing 112.

In detail, in the embodiment, the material of the shielding shell 112 is substantially metal, which is used for electromagnetic shielding effect on the circuit board module 120 disposed therein to prevent external electromagnetic waves from interfering with the normality of the circuit board module 120. Operation. However, in order to prevent the antenna 114 from being shielded by the shielding case 112, it is necessary to partially protrude the radiator 114b of the antenna 114 outside the shielding case 112 without affecting its normal operation. However, in the assembly process of the conventional electronic device, the antenna 114 is directly assembled from the second side S2 on the shielding case 112. Although the assembled structure can prevent the antenna 114 from being shielded, the antenna 114 is repaired or When the replacement is made, the assembly structure is required to be disassembled from the first side S1 by the circuit board module 120 and the shielding housing 112 relative to the casing 140, and then can be removed from the second side S2 of the shielding housing 112. The antenna 114 is mounted, which causes considerable inconvenience.

Therefore, the antenna module 110 of the present invention forms the opening 112a on the shielding case 112, so that when the base 114a of the antenna 114 is assembled to the shielding case 112, the radiator 114b of the antenna 114 can partially pass through the opening 112a. Projecting to the second side S2 of the shield housing 112. Since the material of the casing 140 of the present embodiment is plastic, the electromagnetic wave energy emitted by the antenna 114 of the present embodiment is generally not affected by the shielding effect of the shielding casing 112 as in the conventional structure, and thus the antenna 114 is assembled. The disassembly and assembly mode can be performed from the first side S1 of the shielding housing 112. Therefore, when the display module 130 is opened relative to the casing 140 (ie, the display module 130 is opened relative to the shielding housing 112), the user can The antenna 114 is directly attached and detached by visual observation, thereby improving the detaching efficiency of the electronic device 100.

On the other hand, in the embodiment, the base 114a of the antenna 114 is a circuit board having a metal layer M1, and is assembled on the shielding case 112 by screws 116 (in another embodiment, the base is also Can be a metal plate). This allows the metal layer M1 of the pedestal 114a to be used as the grounding end of the radiator 114b. When the pedestal 114a is assembled to the shielding housing 112, the metal layer M1 can still close the opening 112a of the shielding housing 112, thereby perfecting The shielding effect of the shield housing 112 on the circuit board module 120 therein is shielded.

In addition, in the embodiment, the material of the casing 140 is non-metal, which is only used as an appearance component of the electronic device 100. In another embodiment of the present invention, the electronic device can also be shielded. The housing is used as its exterior member, that is, the display module is directly releasably assembled to the shielding housing, but the radiator still needs to protrude from the first side S1 outside the shielding housing to enable the antenna to operate normally.

In summary, in the above embodiment of the present invention, the electronic device is configured by shielding the opening of the housing and assembling the base of the antenna module from the same side of the circuit board module to the shielding housing. And achieve its assembly effect. In addition to allowing the radiator of the antenna module to protrude through the opening and protruding beyond the shielding case, the structural features allow the user to disassemble the antenna module without stepping through the pieces. Therefore, the antenna module of the present invention and the electronic device using the same can effectively shorten the disassembly and assembly steps and improve the efficiency of the assembly process.
