Wireless communication device

The present invention relates to a wireless communication device, and more particularly to a wireless communication device that transmits and receives signals using a fixed device.

At present, the communication mode of the general public has slowly entered the era of wireless communication, so the use rate of wireless communication devices in various occasions is getting higher and higher, such as mobile phones, smart phones, multimedia playback. Various small wireless communication devices have been gradually developed and become electronic products that people must have in their daily lives.

Generally, the way in which the wireless communication device receives and processes the signal is usually after receiving the signal through the antenna, then transmitting the signal received by the antenna to the circuit, and then starting a series of signals received by the antenna. deal with. For example, taking the internal view of the conventional wireless communication device illustrated in FIG. 1 as an example, the conventional wireless communication device 100 includes a lower case 110, a substrate 120, a screw 130, an antenna 140, an impedance matching circuit 150, and a transceiver 160. The antenna 140, the impedance matching circuit 150 and the transceiver 160 are disposed on the substrate 120.

Looking further at the structure of the conventional wireless communication device 100, a conductive hole 121 is formed at a corner of the substrate 120, and the lower housing 110 has a nut 111 corresponding to the conductive hole 121. The screw 130 is used to penetrate the guide hole 121 and is locked in the nut 111 to fix the lower casing 110 and the base plate 120. It should be noted that the screw 130 must be disposed at the corner of the substrate 120 on the premise of miniaturization of the conventional wireless communication device 100. Furthermore, in order to avoid the influence of the handheld effect on the antenna 140, the antenna 140 may also be disposed at the periphery of the substrate 120.

However, when the antenna 140 and the screw 130 are disposed at the corner of the substrate 120 at the same time, the ability of the antenna 140 to transmit and receive electromagnetic signals is affected by the screw 130. Here, in order to improve the transceiving capability of the antenna 140, the antenna 140 must be disposed at a specific distance (for example, 1 mm) or more from the screw 130. In other words, the conventional wireless communication device 100 must consume more hardware space to improve the transceiving capability of the antenna 140.

The present invention provides a wireless communication device that uses a body portion of an antenna to fix a substrate and a housing, thereby reducing the hardware space of the wireless communication device.

The invention provides a wireless communication device comprising a casing, a substrate and an antenna. The substrate and the antenna are disposed in the housing, and the antenna includes a body portion. In overall operation, the antenna receives or transmits an electromagnetic signal using its body portion. In addition, in view of the structure of the wireless communication device, the body portion of the antenna has a recess corresponding to the side of the substrate. On the other hand, since the body portion of the antenna is locked to the housing, the substrate can be fixed in the housing through the antenna. In other words, the above-mentioned antenna not only can transmit and receive electromagnetic signals, but also has the function of fixing the substrate.

In an embodiment of the invention, the body portion includes a first component and a second component. Wherein, the first component is used to form a groove with the side shape of the substrate, and the second component is used for connecting the first component and being fixed to the casing.

The impedance matching circuit 240 and the transceiver 250 are disposed on the substrate 220.

In overall operation, the antenna 230 receives or transmits an electromagnetic signal using the body portion 231. Since the impedance matching circuit 240 is coupled to the transceiver 250 and the antenna 230, the electromagnetic signal received or transmitted by the antenna 230 will flow between the transceiver 250 and the antenna 230 through the impedance matching circuit 240. Here, the impedance matching circuit 240 is used to cause the impedance of the antenna 230 to match the impedance of the transceiver 250, so that the energy loss formed when the electromagnetic signal flows between the transceiver 250 and the antenna 230 can be reduced.

Here, the extension portion 232 is coupled to the body portion 231 through the metal film 222, so that the antenna 230 can further receive or emit electromagnetic signals by using the extension portion 232.

It should be noted that those skilled in the art should know that as long as the extension portion 232 and the body portion 231 are coupled to each other, the antenna 230 can use the extension portion 232 to transmit and receive electromagnetic signals. Therefore, for the manner of coupling the extension portion 232 and the body portion 231, the embodiment is merely an example that can be implemented. However, the skilled person can arbitrarily change the coupling between the extension portion 232 and the body portion 231 as required by the design. the way.

In addition, the body portion 231 and the extension portion 232 of the present embodiment are made of a metal material, and the metal material constituting the body portion includes aluminum, steel, stainless steel, iron, copper, phosphor bronze, beryllium copper, and the like. On the surface of metal, it can also be coated with metal, such as nickel, zinc, etc. It should be noted that the body portion 231 of the embodiment may be a screw, and the extension portion 232 may be a metal wire. Therefore, for the design of the antenna 230, those skilled in the art can change the frequency range in which the antenna 230 transmits and receives electromagnetic signals by changing the length of the screw or the length of the wire of the metal wire.

With continued reference to FIG. 2, in this embodiment, the housing 210 includes a lock 211, an upper housing 212, and a lower housing 213. The upper casing 212 and the lower casing 213 are stacked on each other, and a cavity is formed to receive the substrate 220 and the antenna 230. In addition, the locking member 211 is disposed in the cavity formed by the upper casing 212 and the lower casing 213, and the locking member 211 is fixed to the lower casing 213 at a position corresponding to the guiding hole 221, so that the body portion 231 is locked. It is paid in the lock firmware 211.

It should be noted that, in this embodiment, a locking manner has been exemplified, so that the substrate 220 is fixed in the housing 210 through the body portion 231. It should be understood by those skilled in the art that the locking manner of the body portion 231 and the locking member 211 includes a plurality of types. Therefore, as long as the body portion 231 of the antenna 230 is used to fix the substrate 220 to the housing 210, it is already It is in line with the spirit of the present invention. For example, an exploded view of the housing and the substrate illustrated in FIG. 3 is taken as an example. Referring to FIG. 3, when the upper casing 212 has a guide hole 241 corresponding to the lock 211, the body portion 231 can be locked into the lock 211 through the guide hole 241. In other words, the body portion 231 at this time is fixed in the locking member 211 through the guiding holes 241 and 221 at the same time, so that the substrate 220 is more stable in the housing 210.

In addition, since the body portion 231 is locked in the locking member 211, that is, the body portion 231 and the locking member 211 are coupled to each other, when the material of the locking member 211 is a metal material, the antenna 230 is further utilized. The firmware 211 receives or transmits electromagnetic signals. It should be noted that the lock 211 listed in this embodiment may be a nut or a self-tapping.
