1 is a plan view of a wireless communication module-integrated optical disc drive according to an embodiment of the present invention, FIG. 2 is a side view of the X direction of FIG. 1, and FIG. 3 is a side view of the Y direction of FIG. 1.

Hereinafter, a wireless communication module integrated optical disc drive according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 3.

Referring to FIG. 1, an optical disc drive incorporating a wireless communication module according to an embodiment of the present invention includes an optical disc drive 10, a wireless communication module including an antenna unit 30 and a wireless communication circuit unit 20.

The optical disk drive 10 is a disk drive that uses laser light or electromagnetic waves near the electromagnetic spectrum to read and write data.

In electronic devices such as computers, optical discs are used to store data and can be used to read or write data.

In the case of an optical disc drive, data can be recorded using media such as CD, DVD, Blu-ray Disc. The optical disc drive may also be applied to independent electronic devices such as a CD player, a DVD player, and a DVD recorder.

The optical disk drive rotates the optical disk by a spindle motor mounted therein, and reads the data stored in the optical disk by a pickup lens that reads information from the light reflected by irradiating laser light. The pickup lens may be designed to move the data of the optical disc from the radial direction of the optical disc, from the center where the spindle motor is installed, to the outer edge of the optical disc. By rotating the optical disc, data can be read from the optical disc.

Various components such as a spindle motor, a laser, and a pickup lens used in the optical disk drive according to an embodiment of the present invention may be accommodated in the case 11 and provided. Accordingly, various parts such as a spindle motor, a laser, and a pickup lens are accommodated in the case to implement a single optical disc drive module and protect the parts from the outside.

According to an embodiment of the present invention, the case 11 may be made of metal. In the case of the optical disk drive, the data is processed by using the laser light, so the light between the internal and external environment should be blocked. Spindle motors, lasers, pickup lenses, etc. may use metal casings for precise fixation.

In the metal case, the antenna unit of the wireless communication module may be grounded to function as a ground terminal. Thus, according to one embodiment of the present invention, the metal case can also be used to protect the components of the optical disc drive and also to ground the antenna unit.

According to an embodiment of the present invention, the wireless communication module may be formed of an antenna unit 30 and a wireless communication circuit unit 20.

The antenna unit 30 may be formed to include an antenna pattern 31 and a feeding unit 33.

The antenna pattern 31 may be formed to have a predetermined pattern according to a desired frequency band in order to transmit and receive a signal.

The antenna pattern 31 may be a patch antenna attached to a case. The antenna unit 30 may be formed by attaching the antenna pattern to the case, and the space occupied by the antenna unit 30 may be minimized because the antenna pattern is attached to the case.

In addition, when providing a space for the separate antenna unit 30, the size and shape of the antenna pattern could be limited to the limited space. However, in the case of the present invention, since the entire space of the case surface may be utilized, constraints on the shape and size of the antenna pattern may be reduced.

The feeding unit 33 may connect an antenna unit and a wireless communication circuit unit. A cable may be connected to the feeding unit 33 to transmit a signal received from the antenna unit to the wireless communication circuit unit.

A ground part 35 may be formed in the case 11. A ground part 35 for grounding the antenna unit may be formed in the case 11 made of metal. Accordingly, the antenna unit may be grounded by connecting to the ground portion 35 formed in the case 11 without forming a separate ground terminal.

According to one embodiment of the invention coaxial cable may be used. The ground line may be connected to the ground part 35 and the signal connection line may be connected to the feeding part by using a coaxial cable having a signal connection line and a ground line coaxially formed.

Since the antenna unit is grounded to the case 11 made of metal, the radiation efficiency of the antenna unit can be increased, and the signal reception efficiency can be further increased.

Referring to FIG. 1, the wireless communication circuit unit 20 may include a substrate 21, a circuit unit 23, and an antenna connection unit 25.

The substrate 21 may serve to electrically connect the circuit unit 23 and the antenna connection unit 25 mounted thereon.

The circuit unit 23 may be a circuit for a wireless communication module. The antenna connection unit 25 may be electrically connected to the feeding unit 33 of the antenna unit 30 through a cable 40.

According to an embodiment of the present invention, the wireless communication circuit unit 20 may be fixed to the case 11. The space occupied by the wireless communication circuit unit 20 may be minimized by being fixed to the stepped portion 13 formed in the case 11.

Guide grooves 15 may be formed in the substrate 21. The screw 21 is fastened to the guide groove 15 to fix the substrate 21 to the case 11.

Screwing may affect the space in which the optical disc rotates. Accordingly, according to another embodiment of the present invention, the fixing protrusion may be formed in the case 11 or the stepped portion 13 of the case.

The substrate 21 may be fixed to the case 11 by forming a fixing protrusion corresponding to the guide groove 15 on the substrate and fitting the fixing protrusion to the guide groove 15.

By forming the guide groove 15 in the manner described above and forming and connecting the screw or the fixing protrusion, the coupling between the wireless communication module and the case can be simplified, and the reliability that is not separated by dropping or vibration can be ensured.

Referring to FIG. 2, according to an embodiment of the present disclosure, an optical disk drive connector 17 may be formed in the case 11, and a connector 27 for a wireless communication module is mounted on the board 21. The connector 27 for a wireless communication module can be formed.

The optical disk drive connector 17 can be used to connect an external component and an optical disk drive, and the wireless communication module connector 27 can be used to connect an external component and an optical disk drive.

In the optical communication module integrated optical disc drive of the present invention, a connector for an optical disc drive and a connector for a wireless communication module may be formed to be connected to the optical disc drive and the wireless communication module, respectively.

1 and 3, the cable 40 may be formed to electrically connect the antenna unit 30 and the wireless communication circuit unit 20.

One end of the cable 40 may be connected to the antenna connection 25 of the wireless communication circuit unit 20. The antenna connector 25 may be formed in a terminal form on a substrate so that one end of the cable 40 is soldered onto the antenna connector 25.

The other end of the cable 40 may be connected to the feeding part 33 of the antenna unit 30 and may be connected to the feeding end 33 by soldering. In addition, the antenna unit 30 may be grounded by designating a ground part 35 in a case of a portion adjacent to the antenna unit 30 and soldering a cable to the ground part 35.

The ground part 35 may be formed at various points on the surface of the case formed of metal, thereby improving design freedom of the ground part 35.

The antenna unit 30 should be arranged in consideration of the signal reception rate and the interference effect. For example, the length of the cable 40 becomes long when the circuit unit is disposed separately from the circuit unit, such as a monitor periphery of the notebook. The longer the cable, the worse the performance of the antenna.

However, in the case of the present invention, since the antenna unit 30 and the wireless communication circuit unit 20 are formed simultaneously in the case 11, the length of the cable 40 can be shortened.

Therefore, in the case of the present invention, since the antenna unit 30 and the wireless communication circuit unit 20 are formed at the same time in the case 11, deterioration of antenna performance due to cables can be prevented.

In addition, the longer the cable, the higher the manufacturing cost. However, in the present invention, since the length of the cable is shortened, the manufacturing cost can be lowered.

4 illustrates a wireless communication module-integrated optical disc drive including an antenna unit 30 'having an antenna pattern 31' according to another embodiment of the present invention.

In the case of the present invention, the case 11 having the components for the optical disc drive may be utilized as an antenna unit. In particular, it can be utilized to ground the antenna unit.

The antenna pattern 31 ′ may be changed into various shapes according to the shape of the case 11 or the housing of the electronic device.

The antenna pattern 31 ′ may have various sizes and shapes according to the surrounding environment or the implementation environment.

According to an embodiment of the present invention, the wireless communication module may be a WiFi module, but is not necessarily limited thereto.

In the present invention, since the WiFi module integrated optical disk drive is provided, the wireless device can be wirelessly connected to various devices by mounting it on an electronic device such as a portable computer, and an electronic device capable of using high-speed Internet can be provided.

According to an embodiment of the present invention, the wireless communication module integrated optical disc drive may be applied to an electronic device. The wireless communication module integrated optical disc drive of the present invention can be applied to a housing of an electronic device. The optical disk drive and the wireless communication module may be applied to various electronic devices.

Within an electronic device, an optical disc drive and a wireless communication module can be applied with a minimum of space. Accordingly, it can be very advantageously applied to the miniaturization of electronic devices.

In case of separately applying the wireless communication module and the optical disk drive, the wireless communication module has to go through a complicated and many processes, such as mounting the wireless communication module separately and arranging the cables of the wireless communication module.

However, in the case of the present invention, since the wireless communication module integrated optical disk drive is mounted inside the electronic device only, the wireless communication module and the optical disk drive can be mounted without going through a separate cable arrangement process and antenna installation process. It can be simple.

In addition, the wireless communication module-integrated optical disc drive of the present invention is particularly applicable to portable computers. That is, the wireless communication module integrated optical disc drive may be mounted in the housing of the portable computer.

Accordingly, since a portable computer has a very limited space, it is possible to use a wireless communication module integrated optical disk drive to make the most of the space. And the manufacturing process can be very simple.

In addition, a wireless communication module integrated optical disk drive may be mounted to connect to a wireless access device, and a portable computer having excellent antenna performance may be implemented.
