Shortwave communication device

A shortwave communication device includes first and second carriers, a processing unit, first and second transmission units and a flexible connecting portion, and the first and second transmission units are installed on the first and second carriers respectively, and the first transmission unit is coupled to the processing unit, and the flexible connecting portion is coupled between the first and second carriers, and the flexible connecting portion has a connected line for constituting an electric connection between the processing unit and the second transmission unit. With the flexible connecting portion, relative position of the first and second carriers can be changed freely to expand the transmission range and enhance the transmission effect.

FIELD OF THE INVENTION

The present invention relates to a shortwave communication device, in particular to the shortwave communication device capable of expanding the transmission range and enhancing the transmission effect.

BACKGROUND OF THE INVENTION

As science and technology advance, modern consumption pattern is changed. For convenience, plastic money has become increasingly more popular and used extensively in our daily life. For example, electronic purse is used extensively in public transportation electronic fee collection systems, and the electronic purse comes with a card structure and contains a non-contact sensor chip (such as a near-field communication chip) capable of registering the monetary value purchased by users. When use, the electronic purse is placed near a sensing area, and an electromagnetic induction effect produced by the sensing area will magnetically induce the non-contact sensor chip of the electronic purse and re-compile the data in the non-contact sensor chip such as increasing the monetary value (which is an operation of adding value), decreasing the monetary value (which is an operation of making a payment), or adding a remark for recording the number of transactions. Therefore, consumers no longer need to make payment by cash or credit card, so as to improve the convenience of consumption.

In general, users generally place the electronic purse with their personal belongings (such as a handbag) when using the electronic purse, and the handbag may contain many articles, particularly those made of metal or conductive materials (such as a mobile phone or a flat PC) which will shield the electronic purse easily. As a result, the transmission performance of the electronic purse may be affected adversely.

SUMMARY OF THE INVENTION

Therefore, it is a primary objective of the present invention to provide a shortwave communication device capable of expanding the transmission range and enhancing the transmission effect.

To achieve the foregoing objective, the present invention provides a shortwave communication device comprising: a first carrier, a second carrier, a processing unit, a first transmission unit, a second transmission unit and a flexible connecting portion, wherein the first and second transmission units are disposed on the first and second carriers respectively, and the first transmission unit is coupled to the processing unit, and the flexible connecting portion is coupled between the first and second carriers, and the flexible connecting portion has a connected line for constituting an electric connection between the processing unit and the second transmission unit.

With the flexible connecting portion, relative position of the first and second carriers can be changed freely to expand the transmission range and enhance the transmission effect.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

The technical characteristics of the present invention will become apparent with the detailed description of the preferred embodiments accompanied with the illustration of related drawings as follows.

With reference toFIGS. 1 and 2for a perspective view and a schematic block diagram of a shortwave communication device of the present invention respectively, the shortwave communication device1comprises a first carrier10, a second carrier20, a processing unit30, a first transmission unit40, a second transmission unit50and a flexible connecting portion60.

The processing unit30and the first transmission unit40are installed on first carrier10; the first transmission unit40is coupled to the processing unit30; the processing unit30is a non-contact sensor chip; the second transmission unit50is installed on the second carrier20; the first transmission unit has a first antenna coil; and the second transmission unit50has a second antenna coil.

The flexible connecting portion60is coupled between the first and second carriers10,20, and the flexible connecting portion60has a connected line61for constituting an electric connection between the processing unit30and the second transmission unit50, wherein the flexible connecting portion60is a flexible flat cable.

When use, the flexible connecting portion60can be used for changing the relative positions of the first and second carriers10,20freely as shown inFIGS. 3 and 4, and the first and second carriers10,20are arranged with an interval apart from each other, and an electronic appliance70can be disposed between the first and second carriers10,20, and the flexible connecting portion60is provided for situating the first carrier10on a surface of the electronic appliance70, and the second carrier20on the other opposite surface of the electronic appliance70. When a user uses the shortwave communication device1for e-Commerce, the first and second transmission units40,50disposed on both surfaces of the electronic appliance70respectively can be used to expand the transmission range to both sides of the electronic appliance70without creating a shielding effect to the electronic appliance70or affecting the transmission effect. Of course, the aforementioned electronic appliance can be a mobile power supply or a portable electronic device.

Further, a positioning structure can be installed between the electronic appliance and the first and second carriers in accordance with a preferred embodiment as shown inFIG. 5, and the positioning structure can be a slot71formed on a surface of the electronic appliance70and provided for inserting and positioning the first and second carriers10,20; or the positioning structure can be an attaching unit in accordance with another preferred embodiment as shown inFIG. 6, wherein the attaching unit comprises a main body72and an attaching portion73disposed separately on both opposite surfaces of the main body72, and each attaching portion73is provided for attaching and positioning onto surfaces of the electronic appliance70and first and second carriers10,20, so as to achieve the fixing effect.

In addition, the shortwave communication device1can be installed in the electronic appliance70as shown inFIG. 7. Similarly, the flexible connecting portion60can be used for changing the relative positions of the first and second carriers10,20, so that the first and second carriers10,20can be disposed on opposite upper and lower sides in the electronic appliance70respectively.

In summation of the description above, the present invention improves over the prior art and complies with the patent application requirements, and thus is duly filed for patent application. It is noteworthy that while the invention has been described by way of example and in terms of a preferred embodiment, it is to be understood that the invention is not limited thereto. To the contrary, it is intended to cover various modifications and similar arrangements and procedures, and the scope of the appended claims therefore should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements and procedures.
